ADEMCO 694 4 Channel Digital Communicator Instruction Manual

694 4 Channel Digital Communicator
Instruction Manual

GENERAL INFORMATION:

The 694 is a 4 channel digital communicator that transmits coded messages over the telephone system to a digital receiver located at a central monitoring station.  Speciafleased lines are not required.
To accommodate various receivers, the 694 can transmit in three formats: 1) Ademco Standard (LOW SPEED) (and Silent Knight), 2) Ademco HIGH SPEED or 3) SESCOA/Franklin/DCI.
The 694 consists of a,printed circuit board and plastic housing that may be installed in any suitable encfosure;such as a No. 204 or 205 cabinet, qr.in the same cabinet with an  Alarm Processing Center.
The 694 may be powered from a 6V. DC filtered rechargeable source (or from 12V. DC by cutting BLUE and GREEN jumpers), such as (for 6V) an Ademco No. 492 or 493  Battery Pack. Alternatively, a 6V. DC unfiltered full-wave rectified swrce may be used (by cutting only the GREEN jumper). Caution: The latter source must not contain  a power transfer relay (transfer must be accomplished without interruption). 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 or 497) that cannot supply at least 75 mA continuously.
A wmmon power supply from a control panel can be used, even with bells connected to the control (No. 1026 or 1026 Alarm Processing Centers may not be used as they  contain Ni-Cad batteries such as those precluded above).
The 694 may be triggered by: 1) Application (or removal) of 4512V DC (battery or filtered full wave rectified) from an alann control or other source, 2) Dry contact closure  (or opening). The unit may not be triggered from an unfiltered rectified source.
The 694 is easily programmed by the positioning of four channel code leads on an 8 pin channel code selector block and the insertion of a programmed PROM (Programmable Read Only Memory) Chip, such as the 691. PROM Chips can be programmed by Ademw or (with the No. 690 Programmer) by the installer.
The 694 has built-in line seizure and telephone line surge arrestors. Line seizure automatically disconnects all tele phones in the premises on the same line with the  communicator whenever the 694 is activated, to insure transmission without interruption. Surge arrestors help protect the unit from voltage surges on the telephone line.
The 694 is compatible with the Ademw family of ancillary communicator accessories, including the following:

OPERATION:

When a channel is activated, transmission to the central monitoring station occurs as follows:

1. After the normal 166 millisecond response time (or 16 seconds delay, if so programmed) the 694 executes line seizure and forces a 1.6 second hang-up to insure a  disconnect if an outgoing call was being made.

2. Next, the 694 checks for dial tone. To shorten the time required for contacting the central monitoring station, the 694 listens for internal dial tone as well as external  (telephone company) dial tone.

3. lf dial tone is detected, the 694 immediately and automatically dials the preprogrammed telephone number, which can consist of up to 4 access digits and up to 12 digits  in the main (telephone company) number. Two telephone numbers can be programmed and dialed as explained in PROGRAMMING OPTIONS. Furthermore, the unft can be programmed to dial “touch tone” in lieu of the slower “pulse dial” method.
   The probability of immediate dial tone detectionis high, but if an internal dial tone is not “heard” within 5 seconds, or an external (telw) dial tone is not “heard” within  11 seconds the unit will dial anyway, on the assumption that the connection may be good even though the dial tone is not clear. (Note: A programming option is available that will extend the 11 second telw waiting period to 30 seconds. See “Extended Dial Tone Waft” option described later.)

4. When connection is made with the central monitoring receiver, a “handshake” tone (acknowledgment) is sent over the telephone lines by the receiver to the 694. This  “handshake” confirms, to the unit, that wnnection has been completed to the receiver.
   If “handshake” is not received within 30 seconds (69 seconds, if so programmed), the communicator will diswnnect itself from the telephone line. After waiting long  enough (approximately 30 seconds) to disconnect any outgoing or incoming calls which might interfere with dialing (“anti-jam” which only works in “called party” control exchanges), the 694 will reconnect to the tele :pne line, and again seize the line, check for dial tone and dial as described in Steps 1.2 and 3.
   If necessary, the 694 will make up to a total of 8 attempts (or “Unlimited Attempts”, if so programmed) to reach the central monitoring station via primary and/or  secondary programmed telephone numbers. See PROGRAMMING OPTIONS. (Note: If the “Dual Report” option, described later, is selected, the unit will make up to  8 attempts to reach each telephone number.)

5. Upon receipt of the “handshake” (acknowledgment) tone from the receiver, the 694 will s&t transmlttlng Ita message(s) in LOW SPEED or HIGH SPEED format,  depending upon the type of acknowledgment tone iq received (assuming the 694’s SESCOA option has not been selected) as described in REPORTING FORMATS.
   Since faulty phone lines can distort the numbers, the 694 sends each message up to 4 times while the receiver compares each message with the one before ft. As soon as  the Receiver detects 2 successive identical messages, it considers the transmission “valid” and sends a “kiss-off” tone to the Communicator.
   If the 694 does not receive the “kiss-off” tone(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 “Unlimited  Attempts”, if so programmed, will be made to reach the central monitoring station via primary and/or secondary programmed telephone numbers. See  PROGRAMMING OPTIONS. Note: If the Dual Report option is selected, the unit will make up to 8 attempts to reach each telephone number.

6. In the event that “handshake” or “kiss-off” is not received, the 694 hangs up and tries again. If necessary, the unit will make up to a total of 8 attempts (or “Unlimited  Attempts”, if so programmed) to reach the central monitoring station, via primary and/or secondary telephone numbers (up to 8 attempts to reach each telephone number if the “Dual Report” option is selected). If, after these attempts, the 694 has not made contact and received “kiss-off’ it will shut down and stop dialing (unless programmed for “Unlimfted Attempts”).

REPORTING FORMATS:

If the 694 is programmed for an Ademw format (that is, the SESCOA system programming option described under PROGRAMMING OPTIONS has not been selected), it  will automatically respond at HIGH SPEED to a high speed acknowledgment tone and at LOW SPEED to a low speed (or standard) acknowledgment tone. No special m- programming of the PROM chip or communicator is required for HIGH SPEED. Only the last 3 digits of the 4 digit subscriber identification code will be sent at LOW  SPEED; therefore, to ensure the same identification at HIGH SPEED as at LOW SPEED, program the first digit as a “0”.
As the number of subscribers calling into the central monitoring station increases beyond 1000 (subscriber identification number 999) the No. 685-2 Line Cards can easily be  modified to send only the high speed acknowledgment tone. Subsequent connected additional No. 694s may then be programmed with subscriber numbers 1000 through  9999.
CAUTION: A ‘No. 685 Digital Alarm Receiver, when equipped with a No. 685-2 Line Card for Ademco High/Low Speed Format, has the capability of sending both high  and low speed acknowledge signals when called; therefore, it is possible (with certain telephone line problems) for a No. 694 to reply to a receiver in either HIGH or LOW  SPEED format. It is recommended that when the number of subscribers on‘one telw rotary exceeds 999, the No. 685-2 line cards be wnverted to high-speed only by cutting  the appropriate jumper on the No. 685-2’s circuit board (see the No. 685’s installation instructions).

Ademco Low Speed Reporting Format:
Receipt by the 694 of the standard (LOW SPEED) acknowledgment 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 wnsisting of the last 3 digits of the 4 digit subscriber identification number and a 1 digit channel code, as  selected, for the channel that triggered.
If more than one channel has triggered, the triggered channels will report in order of priority (i.e.: low CHANNEL ZONE numbers first) unless subsequent channels trigger  while one or more channels have commenced transmission. Each channel message must receive “kiss-off” before the next is sent.
Example: If Channels A and B of Subscriber 1890 go into alarm, the 694 will respond as follows, in conjunction with’an Ademw 660 or 685 (or Silent Knight, SESCOA,  Franklin or DCI) Receiver (codes of 3 for channel A and 6 for channel B are assumed here.)

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.
Other examples of LOW SPEED format appear in the PROGRAMMING OPTIONS section.

Ademco HIGH SPEED Reporting Format:
Receipt by the 694 of a HIGH SPEED acknowledgment tone frpm a No. 885-2 Line Card in a No. 685 Digital Alarm Receiver will result in HIGH SPEED format transmissions, each containing 13 digits as follows:
4 SUBSCRIBER IDENTIFICATION (Account No.) DIGITS
8 STATUS DIGITS indicating the individual status of each of the 8 CHANNEL CODE positions (whether assigned to a particular channel, or not).
1 FINAL DIGIT (always “7” with the 694).
The time from detection, by the No. 685, of a call from the communicator, through transmission of two successive 13 digit messages, to kiss-off, is less than 5 seconds  [corresponding time for LOW SPEED format would be 15 seconds or more, depending upon the number of channels or type of messages (closing report, for example) to be sent].
OPEN/CLOSE programming is restricted to a single channel when standard LOW SPEED Ademw (or SESCOA) format is used (since the particular channel is not identified on CLOSING). When HIGH SPEED format is used, however, this restriction does not apply since each channel’s status is sent individually (see Channel  Programming Options). STATUS DIGITS applicable to each of the CHANNEL CODE positions are:

1
2
3
4
‘5
6| NEW ALARM (previously unreported)
NEW OPENING (previously unreported)
NEW RESTORE (previously unreported)
NEW CLOSING (previously unreported)
NORMAL (no event since previously reported RESTORE or CLOSING)
PREVIOUSLY REPORTED ALARM (OR OPENING) STILL IN EFFECT

‘CHANNEL CODE positions not assigned to any channel must be programmed for Inverted operation (see Channel Programming Options) and wili always yield a STATUS  DIGIT of “5”.
Only NEW events: ALARM (or OPENING), or RESTORE (or CLOSING) on any channel will trigger the 694, at which time all 8 CODE positions wifl report.
An ALARM (or OPENING, if so programmed) is triggered by application of an input. A RESTORE (or CLOSING, if so programmed) is triggered by removal of an input.  If the “Inverted Channel” option is programmed (see Channel Programming Options) the words ‘application” and “removal” in the previous sentence should be reversed.
Note that in LOW SPEED format, a selected CHANNEL CODE also serves as the “alarm reporting” code. In HIGH SPEED format, the CHANNEL CODE  corresponds to its position in the format and STATUS DIGITS serve as the channel’s “alarm reporting” codes.

Examples (HIGH SPEED format):
A. At subscriber #5890, channels B (CHANNEL CODE: 2) and C (CHANNEL CODE: 5) go into alarm:

Message:
Channel B:
Channel C:
B. Still at subscrfber #5890. following the events of Example A above, channel B restores (initiating the call) and channel *C remains in alarm.
Message:
Channel B:
Channel C:

C. Subscriber #0135 sends an opening on Channel A (CHANNEL CODE: 3) a new alarm on channel C (CHANNEL CODE: 5) and a restore on channel D (CHANNEL CODE: 6).
Message:
Channel A:
Channel C:
Channel D:

D. After transmission of Example C, subscriber #0135 sends a closing on channel A.
Message:
Channel A:
Channel C:
Channel D:

SESCOA Reporting Format:
When this option is selected (see PROGRAMMING OPTIONS section) the 694 will respond to SESCOA/Franklin/DCI acknowledge and acknowledge-hold signals in SESCOA format. Ademw HIGH SPEED format response, is not possible when the SESCOA format has been selected. Operation is identical to Ademw LOW SPEED format.

PROGRAMMING OPTIONS:
The 694 may be programmed with a number of options which affect its method of sensing alarms and reporting to the central monitoring station. Programming options  (except for channel alarm codes) are contained in a PROM Chip (No. 691) which can itself be programmed by Ademw or (with the No. 690 Programmer) by the installer.  The PROM Chip is inserted in the 694 during installation using the No. 692 Insertion Tool. Remove the 694’s cover by grasping it at the end with the large wiring opening and pull firmly

Channel Codes:
Channel codes are programmed by positioning four (CHANNE.L CODE) flying leads on an 8 pin connector (CHANNEL CODE SELECTOR) block provided on the  694’s circuit board. Channel A’s code is selected with the BROWN lead, Channel B uses RED, Channel C uses ORANGE and Channel D uses YELLOW.
The numerical value of the code is selected by inserting the tip of each wire in the desired connector position as shown in Diagram 1. As shipped, the channel code leads are  positioned for: Code 1 for Channel A (BROWN), Code 2 for Channel B (RED), Code 3 for Channel C (ORANGE), Code 4 for Channel D (YELLOW) but they may be  repositioned in any of the 8 holes for different codes as desired. Note: All four leads must be inserted regardless of the number of channels to be used. The four code positions not used must be PROM proarammed for inverted ooeration.

System Programming Options:
See Diagram 2 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 694 as a whole, while others affect only the desired channel. The options which affect the unit as a whole are:

1. Dual Report: Reports all information to the second telephone number after receiving kiss-off from 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 694 will then make 8 more attempts to report to the secondary number.’
   Note: When Dual Report is used, Unlimited Attempts (System Option 6) should not be programmed.

2. Alternate by Pairs: The 694 will attempt to call 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.

3. Extended Acknowledge Wait: Doubles the acknowledgment wait period from 36 sewnds to 60 seconds. Help- ful on phone networks wfth long switching time.

4. Extended Dial Tone Wait: Triples the telw dial tone waiting period from 11 seconds to 30 seconds. Useful in slow dial tone areas. Note: The internal dial tone waiting  period (5 seconds) is not altered.

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

6. Unlimited Attempts: Causes the 694 to continue making attempts to reach the receiver until “kiss-off” is received, rather than ceasing after 8 attempts. Note: Unlimited  Attempts should not be programmed when Dual Report (System Option 1) is used.

7. SESCOA: Causes the 694 to look for the SESCOA/Franklin/DCI acknowledge and acknowledge hold signals and to report in SESCOA format. If this option is not  selected, the 694 will repond in LOW SPEED (Ademw standard) or HIGH SPEED format.

ChanneLProgramming Options:
In addition to the system options, there are a number of options which can be selected 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 millisecond response time can be extended to 16 seconds to minimize false triggering due to transients.

2. OpenlClose 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 694 must receive signals when the control panel is armed and disarmed. These signals are available directly from the  Nos. 1021/4921,1021-1 a4021 -12 and 1023 Alarm ’ Processing Centers or Nos. 1022 (1022-12) 1024,1025,1026 and 1028 Alarm Processing Centers when used with  the No. 688 (688-l 2) Opening/Closing Switching Module. The signal may be applied to the 694 when the control is armed and removed when the control is  disarmed, or vice versa.
   With the LOW SPEED (Ademw Standard) or SESCOA format, when an input is applied to the Open/Close Channel, it will report the last 3 digits of the 4 digit subscriber identification number contained in the PROM, followed by the CHANNEL CODE number assigned to the channel.
   When the input is removed, an Open/Close Channel will report the subscriber identification followed by an alarm code 9. For example, for subscriber No. 1890 the unit  will report: 890 9 890 9
   “kiss-off”-hang up
   Since the channel is not identified upon removal of input, restrict this method to one channel, unless HIGH SPEED reporting format is to be used. 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 input being removed.

3. Restore Channels: Channels so designatedwill not only report when the input voltage goes high (alarm) but will report again when the input voltage goes low (restore).  In LOW SPEED format, when the input goes high (alarm) the affected channel will report subscriber identification and channel code number, to be followed by “kiss- 0~‘.
   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 code number: then,  after “kiss-off”, the 694 will report the subscriber identification followed by code 9. For example, in LOW SPEED format, should a channel with channel code 4  restore, the message sequence will be: 890 4 890 4 “kiss-off” 890 9 890 9 “kiss-off”-hang up
   If, in addition to being selected as a Restore Channel, a channel is selected as a Long (16 set) Delay Channel, the delay applies only to the input going high (alarm). If the  input goes low (restores), 150 msec delay applies.
   This feature permits the 694 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 orchannels 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 calls, such as fire, holdup, burglary, etc. This channel option takes  precedence over the system options of “Alternate by Pairs” and “Dual Report”.

5. Inverted Channels: Any number of channels may be programmed for inverted operation. This means that the microprocessor will interpret the presence of a voltage on  that channels input terminal as normal (restored). The absence of a voltage will then be treated as abnormal (alarm).
   All alarm reporting and timing features described in channel options 1 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 connecting the channel input as for dry closure, but substituting a closed circuit switch for the open circuit  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 high).
   Simply tie the inputs of channels with assigned codes of 4 and 5 together and then to the control unit. Program the “4” channel (input going low) for invertd operation.  In this case DO NOT program either the “4” or “5” channel for Open/Close or for Restore. Note: 16 set delay, if selected, will apply when signal is removed from the inverted channel as well as when signal is applied to the non-inverted channel.
   Channels with codes 4 and/or 5 or any other combination used this way may be programmed for Long Delay or Second Number Only (as desired) but the option should be applied to both channels: Note: THE FOUR CODE POSITIONS NOT USED BY THE FOUR CHANNEL CODE LEADS MUST BE PROGRAMMED FOR “INVERTED OPERATION”.

INSTALLATION PROCEDURE:

Mounting:
The 694 is self-contained in a plastic enclosure. It is provided with a metal clip that may be slipped onto the edge of the control or other cabinet in which it is installed (and  secured in place with a screw if desired). Alternatively, double-sided tape may be used to secure the unit to the inside of any enclosure.

COnneCtiOnS: (See Diagram 1)

1. With the 694 unpowered, plug a previously programmed PROM (No. 691, programmed by means of a No. 690 Programmer or No. 691 P4 preprogrammed by Ademco)  into the socket provided. See Diagram 1.
   Care should be taken to orient it properly and avoid bending any pins. For best results, use an Ademw No. 892 PROM Insertion Tool. To remove a PROM, use a No.  692-l PROM Removal Tool.

2. Observe the channel code flying leads and make sure that they are inserted in the 8 pin channel code selector block in accordance with the “Channel Codes” section of  PROGRAMMING OPTIONS.

3. Connect the alarm inputs to the appropriate terminals (teninal 1 is used for Channel A, 2 for B, 3 for C and 4 for D) as follows:
   a. DC Signal Triggering: Connect ( + ) to terminal 1,2,3 or 4 and ( – ) to terminal 6.
   b. Dry Contact Triggering: Connect contacts between temrinal5 ( + ) and terminal 1,2,3 or 4. For triggering upon contact closure, use an open circuit contact. For  triggering by contact opening use a closed circuit wntact (in this case, the channel must be programmed for inverted operation).

4. Connect the telephone line (and handsets) to terminals 7,9 and 10. Diagram 1 shows connection via a No. 629 Direct Connect Cord.

5. Connect terminal 8 to a cold water pipe ground using #16. (or heavier) gauge wire.

6. Cut the appropriate GREEN and BLUE jumpers on the 694, if necessary:
   a. If a 6V. DC filtered rechargeable power source is to be used, leave the unit’s GREEN and BLUE jumpers intact.
   b. If a 12V. DC filtered rechargeable power source is to be used, cut the unit’s GREEN and BLUE jumpers.
   c. If a 6V. DC unfiltered full-wave rectified power source is to be used cut only the GREEN jumper.

7. Apply power to the control unit (if it is not already powered) if one is to be used in conjunction wfth the communicator.

8. Connect the power source to the communicator’s terminals 5 (+) and 6 (-) (make certain that the approprfate BLUE and/or GREEN jumpers have been cut, if  necessary…see Step 6). The 694’s dial relay and line seizure relay will be activated for about l/4 second and the unit will initialize to the alarm status present at the input  termi- nals. Any changes in the alarm conditions will be monitored by the 694 and those which require that a call be made will activate the unit.

9. Test the 694 by triggering one of the alarm channels.
