ADEMCO 678 Digital Communicator ALARM Device Instructions

678 Digital Communicator ALARM Device
Instructions

GENERAL INFORMATION:

The 678 is an 8 channel digital communicator that transmits coded messages over ,the telephone system to a digital receiver located at a central monitoring station. Special leased lines are not required. (There is a 9th channel dedicated to user test and optional low ba=y reporting.)
To accommodate various receivers, the 678 can transmit in three formats: I) Ademco (and Silent Knight), 2) Ademco High Speed or 3) Sescoa/Franklin/DCI.
The 678 consi sts of a printed ci rcuit board chassis Bnd cover that may be in&a I led in any suitable enclosure, such as the Nos. 204 or 205 Cabinets, or the lower section of a No: 1023 or 1024 Alarm Processing Center’s cabinet. (Note: The upper section of a No. 1023 or 1024’s cabinet may be used as well, if the 678 is mounted behind or in lieu of the APC’s normal control chassis.)
The 678 may be powered from a 6 or 12V. DC, filtered rechargeable, source [such as (for 6V): Ademco Nos. 492, 493-j. Caution: The Nos. 89 and 89-12 Energy Packs may not be used, nor may sources containing Ni-Cad batteries such as the Nos. 96, 97, 497. A comnon power supply from a control panel can be used, even with bells connected to the control (No. 1026 or 1028 series Alarm Processing Centers may not be used, as they conta in ‘Ni-Cad standby batteries

1. The 678 may be triggered by: I) Application (or removal) of 6-l2V. DC supplied from any alarm control (or other DC source), 2) Dry contact closure, 3) Dry contact opening.
   The 678 is easily programmed by the insertion of a PROM (Programmable ReadgnlY &emorYj Chip, such as the No. 691. PROM Chips can be programmed bv Ademco or with the No. 690 Programmer) by the i nstal ler.
   The 678 has built-in line seizure and telephone line surge arrestors. Line seizure automatically disconnects all telephones in ttie premises on the same line with the communicator whenever the 678 is activated, to insure transmission without interruption. Surge arrestors help protect the 678 from’voltage surges on the telephone line.

The 678 is compatible with the Ademco family of ancillary communicator accessories, including the following:

OPERATION:

When a channel is activated; transm iss ion to the central monitoring station occurs as follows:

1. After the normal 150 millisecond response time (or I6 seconds delay if so programmed) the 678 executes line seizure and forces .a 1.6 second hang-up to insure a disconnect if an outqoinq call was beina made.
   Note: The 678 has a built-in ACTIVATION LED which lights wh&ever the unit is activated.

2. Next, the 678 checks for dial tone. To shorten the time required for contacting the central monitoring station, the 678 can sense internal dial tone as well as external (telephone company) dial tone’.

3. If dial tone is detected, the 678 immediately and automatically dials the preprogrammed telephone number, which can consist of up to 4 access digits and up to I2 digits in the main (telephone company) number. Two telephone numbers can be programmed and dialed as explained in PROGRAMMING OPTiONS. Furthermore, the 678 can be programmed to dial “touch tone” in I ieu of the slower “pulse dial” method. The probability of immediate dial tone detection is high, but ff a dial tone is not detected within II seconds, (.30 seconds, if so programmed), the 678 wi India I anyway, on the assumption that the connection may be good even though the dial’ tone is not clear.

4. W.hen connection is-made with the central monitoring receiver, a “handshake” tone (acknowledgment) is sent over the telephone lines by the receiver to the 678. This “handshake” confirms, to the 678, that connection has been camp leted to the r’ece i ver. If “handshake” is not received within 30 seconds (60 seconds if so programmed), the communicator will disconnect itself from the telephone line. After waiting long enough (approximately 30 seconds) to disconnect any outgoing or incoming calls which might interfere with diali-ng (“anti-jam” which only works in “called party’ control exchanges), the 678 will reconnect to the telephone I i ne, and again seize the line, check for dial tone and dial as described in Steps I, 2 and 3. If necessary the 678 wi I I make up to a total of 8 attempts* (or “Unl imited Attempts”, if so programmed) to reach the central monitoring station via primary and/or secondary programmed telephone numbers. See PROGRAMMING OPTIONS.

5. Upon receipt of the “handshake” (acknowledgment) tone, the 678 will start transmitting its message(s), each consisting of a subscriber identification number and a I digit alarm code corresponding to the number of the channel that tri ggered. Since faulty phone lines can distort the numbers, the 678 sends each message up to 4 times while the receiver compares each message with the one before it. As soon as the Receiver detects 2 successive identical messages, it considers the transmission “valid” and sends a “kiss-off” code to the Communicator. l f more than one channe I has triggered, the triggered channels will report in order of ‘priority (i.e.: low alarm numbers first) unless subsequent channels trigger while one or more channels have commenced transmission. Each channel message must receive “kisgS~ff” before the next is sent.
   Example:
   If Channels 3 and G of Subscriber 1890 go into alarm, the 678 will respond as follows in conjunction with an Ademco 660 (or Silent Knight; SESCOA, Frahkiin or DCI) Receiver:

890
890
“kiss-off”
890
890
Final “kiss-off”| 3
3
6
6
(No. 678 hangs up)
---|---

Note : Only the last 3 digits of the subscriber identification number will in this case be sent. The full 4 digits will be used in conjunction with an Ademco No. 685 High  Speed Receiver (available soon).
If the 678 does not receive the “kiss-off” code(s) by the time it has sent its message(s) four times, it hangs up and dials again. Up to a total of 8 attempts *or “Uni limted Attempts”, if so programmed will be made to reach the central monitoring station via primary and/or secondary programmed telephone numbers. See PROGRAMMING OPTIONS.

6. In the event that “handshake” or “‘kiss-off” is not received’ the 678 ‘hanqs up and tries agaln.
   If necessary, the 678 will make up to a tota I of 8 aTtempts “(or “Un.limi ted Attempts” if so programmed) to reach the central monitoring station,  via primary and/or secondary telephone numbers. If, after these attempts, the 678 has not made contact and received “kiss-off” it will shut down and stop dialing (unless programmed for “Unlimited Attempts”).
   The 678 has a built-in KISS-OFF LED which lights upon receipt of”kiss-of-f” and goes out 8 seconds after completion of all transmission to that telephone number.

*If the “Dual Report” option is selected, the 678 will make up to 8 attempts to reach each telephone number.

PROGRAMMING OPTIONS:

The No. 678 may be programmed with a number of opti.ons which affect its method of sensing alarms and reporting to the central monitoring station.
Programing is contained in a PROM Chip (No. 691) which can be programmed by Ademco or (with the No. 690 Programmer) by the installer:The PROM Chip is inserted
in the 678 during installation.
See Diagram 3 for a reproduction of the form used in programming the PROM chip. It- may be used to record the PROM programming used for the actual installation as well as a guide for requesting a differently programmed PROM. Some of these options affect the unit as a whole, while others affect only the desired channel. The options which affect the units as a whole are:

Systern Programming Options:

1. Low Battery Trigger and Report: Initiates a call to the contral’monitoring  station and sends Code 8 when the rechargeable power source drops beIow ten  5 volts (IOV for a l2V rechargeable source). This report will  not be -. repeated during later alann transmissions.

2. Oval Report: Reports all information to the second telephone number after receiving kissoff fram the receiver at the primary number. In the event that 8 attempts are made, but no “kiss-off” is received from the primary number, the No. 678 wil! then make 8 more attempts to report to the secondary number.
   Note: When Oual Report is used, Unlimited Attempts (System Option 7)should not be programmed.

3. Alternate by Pairs: The dialer will attempt to cal! the primary number twice, then, if “Kiss-off” has not been received, it will make two attempts to reach the receiver at the secondary number. It will alternate by pairs of calls until a total of 8 attempts have been completed, or “kiss-off” is received.

4. Extended Acknowledge Wait: Doubles the acknowledgment wait period from 30 seconds to 60 seconds. Helpful on phone networks with long switching time.

5. Extended Dial Tone Wait: Triples the dial tone waiting period from It seconds To 30 seconds. Useful in slow dial tone areas.

6. Touch Tone Dial: Instructs the communicator to dial touch tone instead of the slower pulse dial method.

7. Untimited Attempts: Causes the 678 to continue making attempts to reach the receiver unt!) “kiss-off” Is received, rather than ceasing after 8 attemots.
   Note: Untimited Attempts should not be programmed when Dual Report (System Option 2) is used.

8. SESCOA: Causes the No. 678 to look for the SESCOA/Franklin/DC! acknowiadge and acknowledge hold signals and to report in SESCOA format. If this option is not selected, the No. 678 will respond in the Ademco standard format.
   For Ademco hi-speed format see instructions accompanying the No. 685 Receiver.

Channel Programming  Options
In addition to the system options, there are a number of options which can be selected and which affect only those channels which the user desires. These are:

1. Long Delay Channels: Any number of channels may be programmed for a 16 second delay. Thus, the normal 150 millisec response time can be extended to 16 seconds to minimize false triggering due to transients.
2. Open/Close Channels: Channels selected as Open/Close Channels will report when the triggering voltage appears as well as when the input voltage is removed.
   In order to transmit opening and closing rounds, the 678 must receive signals when the control panel is armed and disarmed. These signals are available directly from the No. 1023 Alarm Processing Center or Nos. 1022, 1024, 1026 and 1028 Alarm Processing Centers when used with the No. 688 Opening/Closing Switching Module. The signal may be applied to the 678 when the control is armed and removed when the control is disarmed, or vice versa.
   With the standard Ademco or SESCOA format, an Open/Close Channel will report the subscriber identification (the 3 last digits of the 4 digit identification code contained in the PROM) followed by the number of the channel when an input is applied to the channel.
   When the input is removed, an Open/Close Channel will report the subscriber identification (3 last digits) followed by an alarm code 9. For example, for subscriber No. 1890 the No. 678 will report:890
   890
   “Ki ss-off “| 9
   9
   “——hang up
   ---|---

If a channel is selected as both an Open/Close Channel and a Delay Channel, the delay applies to the input being applied and the in- being removed. Since Code?9 can also mean test, use caution.Tso since the channel is not identified upon removal of input, restrict’this method to one channel.

3. Restore,ChanneIs: Channels so designated will not only report when the input voltage goes high (alarm) but will report again when the input voltage goes low (restore). When the input goes high (alarm) the affected channel .will report subscriber identification and channel number, to be followed by “kiss-off”.
   However, when the input goes low, the channel, (if  it is selected as a Restore Channel) will report the subscriber identification followed by the channel number; then, after “kiss-off”, the 678 will report the subscriber identification followed by code 9. For example, should channel 4 restore, the message sequence will be:890
   890
   “kiss-off”
   890
   890
   “kiss-off”| 4
   4
   9
   9
   -hang up
   ---|---

If, in addition to being selected as a Restore Channel, a channel is selected as a Long (I6 set) Delay Channel, the.delay applies only to the input going high (alarm). If the input goes low (restores), 150 msec de lay app I ies. This feature permits the 678 to report a restore on the same call. as it reports an alarm, thus reducing  the frequency
.with which . . emergency services will be notified in the event of false alarms.

4. Secondary Number Only Channels: Any channel or channels may be’selected to call and report only to the secondary number. This feature can be used to force openings and closings to call the secondary number, leaving the primary number open for emergency calIs, such as fire, holdup, burglary, etc. This channel option takes precedence
   over the system optlons of “Alternate by Pal&’ and “Dual Report”.

5. Inverted Channels: Any number of chanhels may be programmed for inverted operation. This means that the mi croprocessor will interpret the presence of a voltage on that channel’s input terminal as normal (restored). The  absence of a voltagewill then be treated ,as abnormal (alarm). All alarm reporting and timing features described in channel options I to 3 (above) still apply, but with the reversed definition of normal and alarm. Inverted operation can be used to obtain triggering upon dry contact opening by hooking up the channel input as for dry closure, but substituting a NC switch for the NO switch. The ability to invert a channel also provides features not otherwise easily
   available. For example, suppose it is desired to send opening and closing information, but code 9 (see Channel Option 2) is found unacceptable. Suppose further.that a code 4 is wanted for closing (input going low) and code 5 for opening (. input going h’igh) . Simply tie the inputs of channels 4 and 5 together and then to the control unit. Program channel 4 (input going low) for inverted operation. In this case DO N’OT program either channel 4 or 5 for Open/Close or for Restore.
   Note: I6 set delay, if selected, will apply when signal is removed from thexerted channel.
   Channels 4 and/or 5 or any other combination used this way may be programmed for Long Delay or Second Number Only (as desired).

The “Kiss-off” (Ring-Back) Feature is an important tool when transmitting test or opening/closing si,gnals. Once “kiss-off” is received, the built-in LED will light and stay on for 8 seconds. By remoti ng an LED or buzzer 1 (Ademco No. 8261) at a convenient location, the customer is advised of a successful transmission to the receiver.

INSTALLATION PROCEDURE:

Mounting:
The 678 may be mounted in a No. 205 Cabinet or any other enclosure that will accommodate it. See GENERAL INFORMATION.
If a No. 205 Cabinet is to be used, mount the cabinet in its desired location and install the communicator chassis in it. Use the upper set of grooves provided at the side edges of the cabinet and secure the chassis with a sheet metal screw through the upper hole in the cabinet’s right edge.

Diagram1 : INSTALLATION OF COMMUNICATOR CHASSIS IN ALARM PROCESSING CENTER. ( eg: No. 1023,1024)

Current models of the Nos. 1023 and 1024 are provided with extra mounting grooves and hole at the sides of their cabinet to accommodate the communicator chassis.
In addition, a small hole is provided in the top of these cabinets to enable the communicator chassis to be mounted vertically behind the alarm processing center’s chassis
after connecting. (See Diagram 1) Note: In cabinets without mounting grooves, the communicator chassis may be sZZi.YFed in place with double sided tape.

Cbnnections: (See Diagram 2)

1. With the 678 unpowered, plug previously programmed PROM (No. 691 programmed by means of a No. 690 oroarammer or No. 69 116 pre-programmed by Ademco) into the socket provided. See Diagram 2. Care shou Id be taken to orient it properly -and avoid bending any pins. For best results, use Ademco No. 692 I.C. Insertion Tool. To remOve a PROM, insert small screwdriver and careful ly pry up.

2. Connect the BLACK flying lead ‘to the neqative power supply terminal.

3. (Optional:) Connect a remote “kiss-off” LED and/or a remote “kiss-off” buzzer, No. 8261 as shown in Diagram I. Use wires with quick-connect female terminals supp lied.

4. (Optional:) Connect a No. 664 test switch or a momentary N.O. test switch. – See terminals 7, 8 and 9 in Diagram 2. Note: The test channel should not be used if any alarm channel is selected as Open/Close, since both the test and closing will be reported as a code 9 (standard Ademco or SESCOA).

5. Connect the alarm inputs to the appropriate termina Is.
   Notes: a. Channel I gives alarm code I, channel 2 gives code 2, etc. If the Low Battery
   b. Trigger and Report option has been programmed do not use Channe I 8, si nce ” low battery” code 11 1, is 8.
   C. For voltage triggering, two ground (.-I positions are provided on the terminal block if needed.
   d. If one or more channels are to be tr‘iggered by dry contacts, terminals 5 and 6 each provide +V dry contact excitation. Each is isolated from power supply positive (+I through a 47 ohm protective resistor. If the remote “kiss- off” buzzer No. 8261 is connected to one of the terminals, it is recommended that dry contact excitation (if required) be obtained from the other one. For triggering by contact closure, use a N.O. contact. For triggering by contact opening use a N.C. contact (the channel-must be programmed for inverted operation).

6. Connect the teI.ephone line <and handsets) via a No. 620 Direct Connect Cord as shown i n Diagram 2.

7. Apply power to the CONTROL UNIT if it is not already powered.

8. If a l2V. DC power source is to be used with the 678, cut the 678’s WHITE . jumper as indicated in Diagram 2.

9. Connect the red flying lead of the 678 to the (+I terminal of the 6 or I2 V rechargeable power source. The 678’s line seizure and dialing relays will be activated, and the two LED’s on the 678 will light. After 8 seconds, both LED’s will be out and the dialing and the line seizure relay will have dropped out. The dialer will now have initialized to the alarm status present at the input barrier strip. Any changes in the alarm conditions will be monitored by the 678 and those which require that a call be made will activate the 678.

10. Test the 678, using the No. 664 test button or N.O. switch (if installed . ..see Step 4) to transmit a code 9 or by triggering one of the alarm channels.

   RE: A) REPORTING FORMATS (LOW SPEED, HIGH SPEED),
   B) KISS-OFF RtNG-BACK CAUTION
   C) PROGRAMMING  FORM for No. 691 PROM
   A) REPORTING FORMATS:
   Substitute the following for Step 5 in the “OPERATION” section that begins on Page 2 of the 8/80 issue of the 678’s installation instructions:

6. Upon receipt of the “handshake ” (acknowledgment) tone from the receiver, the 678 will start transmitting its message(s) in LOW SPEED or HIGH SPEED format, depending upon the type of acknowledgment tone received (assuming the 678’s SESCOA option has not been selected) as described below.
   Since faulty phone lines can distort the numbers, the 678 sends each message up to 4 times while the receiver compares each message with the one before it. As soon as the Receiver detects 2 successive identical messages, it considers the transmission “valid” and sends a “kiss-off” code to the Communicator.
   If the 678 does raot receive the “kiss-off” code(s) by the time it has sent its message(s) four times, it hangs up and dials again. Up to a total of 8 attempts or “Un limited Attempts”, i f so programmed, will be made to reach the central monitoring station via primary’and/or secondary programed telephone numbers. See PROGRAMMING OPTIONS (if the “Dual Report” option is selected, the 678 will make up to 8 attempts to reach each telephone number).

ADEMCO LOW SPEED REPORTING FORMAT
Receipt by the 678 of the standard (LOW SPEED) .acknowIedgment tone from a No. 660 Receiver (or LOW SPEED acknowledgment tone from a No. 685 Digital Alarm.Receiver) will result in LOW SPEED FORMAT transmissions, each consisting of the last 3 digits of the subscriber identification number and a ldigit alarm code corresponding’to the number of the channel that triggered.
If more than one channel has triggered, the triggered channols’will report in order of priority (i.e.: low alarm numbers first) unless subsequent channels trigger while one or more channel s have commenced transmission. Each channel message must receive “kiss-off” before the next is sent.
Example:
If Channels 3 and 6 of Subscriber 1890 go into alarm, the 678 will respond as follows:

890
890
“kiss-off”
890
890
Final “kiss-off”| 3
3
6
6
(No. 678 hangs up)
---|---

Note : Only the last 3 digits of the subscriber identification number will in this case be sent. The full 4 digits will be used in conjunction with the HIGH SPEED FORMAT described next.

AGEMCO HIGH SPEED REPORTING FORMAT
Receipt by the 678 of a hlgh speed acknowledgment tone from a No. 685-2 Line Card In a No. 685 Glgltal Alarm Receiver will result In HIGH SPEED Format transmissions, each contalnlng I3 dlgits as follows: 4 dlglt subscrlber ldentlficatlon number, 8 dlglts deflnlng the status of each of.the eight alarm reportlng channels, and
I dlglt deflnlng the status of the nlnth (test, low battery) channel.

Note:
If the 678 Is progranrned for Adamoo format (that Is, the SESCOA system programntng optlon described under PROGRAMMING OPTIONS has not been selected)
It will automatically respond at HIGH SPEED to a high speed acknowl edgment tone and at LOW SPEED to a low speed (or standard) acknow- ledgment tone.
No special re-programming of the PROM chip or communicator 1s required for HIGH SPEED. Only the last 3 digits of the 4 dfglt sub- scriber I-dentification code will be sent at LOW SPEED; therefore, to ensure the same ldent i f I cat ion at HIGH SPEED as at LOW SPEED, program the f i rst dlgit as a ‘0*‘.
As the,number of subscrlbers calling into the central monitoring statlon Increases beyond 1000 Csubscriber identification number 999) the No.
685-Z Line C&ds caneasily be modified to send sthe high speed acknowledgment tone. Subsequently connected addit’onal No. 678 smay then be programmed with subscri her numbers 1000 through 9999.

For the elqht alarm reporting channels (digits 5 through 121, the channel status codes are as follows:

I
2
3
4
5
6| NEW ALARM (previously unreported)
NEW OPENING ( ”  ” )
NEW RESTORE k ( ”  ” )
NEW CLOSING ( ”  ” )
NORMAL (no event since previously reported RESTORE or CLOSING)
PREV I OUSLY REPORTED ALARt+! (OR OPEN I NG) STI LL IN EFFECT

For the ninth (test, low battery) channel (digit 131, the following channel status codes are used:

7
8
9| NORMAL (no event) NEW LOW BATTERY. (will not re-report
on subsequent calls and will not send restore) TEST
---|---

Note : Only NEW events:
ALARM (or OPENING), or RESTORE (or CLOSING) on’any channel or NEW LOW BATTERY or TEST will trl’gger the 678, at which time all 9 channels will report.
An ALARM (or OPENING, if so programned) is triggered by application of an input.
A RESTORE (or CLOSING, if so. programmed) is triggered by renroval of an input. If the “Inverted Channel ” opt ion is programmed (see Channel Programming Options)
the words ‘lappI ication” and “removal” 1n the previous sentence shou I d be reversed.

Examples (HI &i SPEED format):
A. At subscriber 12890, channels I through 8 are normal and a low baitety ‘(channel 9) Inltiates,a call. The folIowIng tissage wtll be sent:

B. At subscriber #5890, channels 2 and. 5 go Into alarm (and Inltiatb a call) and channel 8, which has previously reported an alarm 1s still trtggered.

C. Still at subscriber #5890, following the events of example D above, channel 2 restores (initiating the call) and channels 5 and 8 remain In alarm:

D. Subscriber 80135 sends an opening on channel 3, a new alarm on channel 5 and a restore on channel 6:

.E. After transmission of Example D, subscrIber.#Ol35 sends a closing on channel 3.

The sending of individual channel status in all HIGH SPEED messages eliminates the ambiguities present in the LOW SPEED format between channel 8 (code 8 in LOW SPEED) and low battery (also code 8 in LOW SPEED). In HIGH SPEED, low battery is reported as a channel 9 status, thus freeing use of channel 8 for alarm reporting
(its use in LOW SPEED having been precluded when low battery reporting was selected).

Similarly, OPEN/CLOSE programming is restricted to a single channel when standard LOW SPEED Ademco (or SESCOA) format is used (to avoid confusing code 9 “close” with code 9 “test”).~ When HIGH SPEED format is used, however, this restriction does not apply since each channel’s status is sent individually.
The time from detection, by the No. 685, of a call from the communicator, through transmission of two successive I3 digit messages to kiss-off, is lass than 5  econds[corresponding time for LOW SPEED format would be I5 seconds or more, depending upon the number of channels or type of messages (closing report, for  example) to be sent].

CAUTION: A No. 685 Digital Alarm Receiver, when equipped with a No. 685-2 Line Card for. Ademco High/Low Speed Format, has the capabi I ity of sending either high or low speed acknowledge signals when called; therefore, it is possible (withTertain telephone line problems) for a No. 678 to reply to a receiver in either HIGH or LOW SPEED format. It is recommend.ed that when the number of subscribers zone telco rotary exceeds 999, the high/low speed line cards be – converted to high speed only by cutting the appropriate jumper on the No. 685-2’s circuit board (see the No. 685’s installation instructions).

SESCOA REPORTING FORMAT
When this option is selected (see PROGRAMMING OPT!ONS section) the 678 will respond to SESCOA/Franklin/GCI acknowledge and acknowledge-hold signals in
SESCOA format. Ademco HIGH SPEED format response is not possible when the SESCOA format has been se I ected.

B) KISS-OFF RING-BACK CAUTION:
Add the following to the paragraph on Page 6 of the instructions that describes the Kiss-off Ri%g’-back Feature:
Caution: Discretion is advised if a remote buzzer (or other audible device) is used in conjunction ‘with a communicator that has a si lent emergency a I arm connected to ‘one of its channels, as the buzzer will sound after such an alarm is sent.

C) PROGRAMMING FORM FOR No. 691 PROM:
Make the following changes to the programming form shown in Diagram 5 on Page IO of the instructions:
Step 3: At the end of this step’s instructions, add: (such as a No. 685).
Step 5: Change the,note pointing to channel 8 to read: Do not use channel, 8 if “Low Battery Trigger ” System Option is selected unless HIGH SPEED reporting format
is to be used. Change the first note pointing to the OPEN/CLOSE option to read:
Restrict “Open/C I ose” to single channel unless HIGH SPEED reporting format is used.
