245-12 Two Wire Remote Station Adapter With Fire
Circuit Instructions
NO. 245-12 TWO WIRE REMOTE STATION ADAPTER WI-FI SUPERVISED FIRE CIRCUIT
GENERAL INFORMATION:
The No. 245-12 Two-Wire Remote Station Adapter permits up to 4 Remote Control
Stations with single LED indicators (such as the Nos. 214, 246, 246R and 5246)
to be connected to 12V controls (such as the No. 1023-12 Alarm Processing
Center) with only two wires. In addition, the No. 245-12 enables complete
status of’the system’s burglar alarm circuits (such as: “not ready for
arming”, “ready for arming”, “alarm memory”, or “armed”) to be indicated by
each remote station’s single LED.
If desired, momentary or lock-in type normally open emergency (panic) switches
(e.g.: Nos. 219, 265, 266, 268 or 269) may be connected across the remote
control station leads instead of to separate wiring from the panel.
A separate section of the No. 245-12 provides: I) A complete supervised fire
circuit; 2) Power output for smoke or products of combustion detectors, 3)
Output for a bell or other signalling device and 4) Normally open contacts
which close on alarm.
OPERATION:
A. Two-Wire Remote Station Adapter Section: Arming and disarming of the system may be carried out at any remote station. Each remote station’s LED will indicate the system’s status as follows:
| LED INDICATOR ON REMOTE STATION | STATUS |
|---|---|
| Off | *Disarmed, Protective Circuit(s), Open or Alarm Stored in Panel’s Memory |
(see Instructions with No. 1023-12)
**Flashing| Disarmed, Protective Circuits Closed (Ready for Arming)
On Steadily| Armed (Ready for Alarm or Disarming)
*LED(s) on No. 1023-12 Alarm Processing Center will be lit for specific zone(s) not ready for arming or flashing for memory in an alarmed zone which has restored. If panel LED is flashing, system may be armed directly without any loss of protection. (To clear panel’s memory and restore flashing condition to remote stations, arm and immediately disarm the system.)
The No. 1023-12 Alarm Processing Center features automatic loop shunting and
may be armed even though one or both of its basic protection zones (not the
delay zone) has a fault, and the remote station LED is not flashing.
NOTE: For details of operation with other controls, see the instructions
that accompany the controls.
When the No. 245-12 is used, the following information supplements the No.
1023-12 Alarm Processing,Center’s installation instructions:
I. A stand-alone keyswitch cannot be used for ON-OFF control of the panel when
the No. 245-12 is used.
2. To silence the alarm bell after a panic or tamper switch is operated, the
No. 245-12 must be reset by its own (or an optional remotely located)
Fire/Panic reset switch, after the panic or tamper switch is returned to
normal. The arm/ disarm status of the system should also be checked since
operation of the panic/ tamper circuit may change the control’s status. 3.
Take special care to observe the AC-POWER LED daily to make sure that it is
lit, to insure that the panel’s standby battery remains charged. Also depress
the control’s BELL TEST switch periodically to check the bell battery and
power supply circuits.
B. Supervised Fire Circuit Section:
Devices such as thermostats and smoke or products of combustion detectors
which may be connected to the No. 245-12’s supervised fire loop will initiate
a fire alarm when their contacts close across the two loop wires. When an
alarm is triggered, the No. 245-I2’s alarm relay latches, providing a nominal
12V. DC output to a fire bell or horn and closing a set of dry contacts which
may be connected to a digital communicator, tape dialer, or as desired.
A reset switch on the No. 245-12, when operated, will reset the fire circuit
(and panic circuit) if all fire detection and panic devices have returned to
normal. Provision is also made for installing an additional switch remotely so
that reset may be accomplished from another location.
An end of line module (No. 633-12) is used to supervise the DC power to smoke
and combustion detectors. If this power is interrupted, contacts in the module
open the fire loop.
A 10,000 ohm end of line resistor is used to provide fire loop supervision. If
the fire loop is opened, the No. 706-12 Mini-Howler (if used with the main
control) will sound as long as the loop remains in the trouble (open)
condition.
INSTALLATION AND WIRING: See Diagrams 1 and 2:**
Each No. 245-12 will permit up to 4 single LED remote stations to be connected
to the control instrument, in parallel, on one or more two wire runs
originating at the control.
The wire size to be used for the entire length of a two wire run depends upon
the distance from the control to the farthest remote station on that
particular run. Use the following tabulation to determine the wire size(s)
needed for the proposed run(s). Twisted pair is recommended for greater
immunity to unwanted induced voltages.
MAXIMUM DISTANCE TO FARTHEST REMOTE STATION| WIRE SIZE| ADEMCO NO. (TWISTED
PR.)
---|---|---
IO0 feet| #22| 289
200| #20| 283
300| #I8| 284
500| #I6| 282
Preliminary:
1. Disconnect the control’s battery and AC power.
2. Install the No. 245-12 in the control’s cabinet as shown in the mounting
detail in Diagram I. The mounting lip provided on the No. 245-12 can be
slipped over the cabinet’s edge without interfering with the ability of the
cabinet’s cover to close and lock.
3. Connect the 6 leads of the No. 245-12 that have quick connect terminals to
the terminal posts in the control as indicated in Diagram I. For AUDIBLE PANIC
ALARM, connect the No. 245-12 and emergency (panic) switches as shown in
Diagrams 1 and 2.
For SILENT PANIC ALARM , connect the No. 245-I2’s VIOLET lead to the
positive (+) triggering by voltage (12V. DC) terminal of a digital
communicator (a non-delay channel is recommended) instead of to the control as
shown in Diagram I. If an external source is used to power the communicator,
also interconnect the control’s negative (-) alarm bell terminal and the
communicator’s negative (-) triggering terminal. Connect emergency (panic)
switches as described in the note following Step 5 below.
To insure proper remote station tamper circuit protection, DO NOT LEAVE THE
VIOLET LEAD DISCONNECTED.
Remote Control Stations:
4. a. Splice the No. 245-12’s ORANGE lead to one of the wires of each two
wire run to be made for the remote control station as shown in Diagram 2.
These will be the negative (-) leads.
b. Splice the other lead of each two wire run to the RED lead of the No.
245-12. These will be the positive (+) leads.
c. At each remote station, make sure the positive (+) and negative (-) leads
of the two wire run are soldered to the remote station’s (+) and (-) points
respectively, as indicated.
d. Three No. 8066 Diodes are included with each No. 245-12 Two-Wire Adapter.
(I) At each tampered remote station (e.g.: Nos. 246, 246R or 5246) connect a
No. 8066 Diode between the tamper switch and lockswitch as shown (observe
polarity) and connect a wire jumper between the LED terminal and the
lockswitch as shown in Diagram 2.
(2) At each non-tampered remote station (e.g.: No. 214) connect the incoming
wires as shown (observe polarity). The diode is already installed.
Emergency or Panic:
5. If desired, lock-in type emergency (panic) switches (e.g.: Nos. 264, 266,
268 or 269) or non-lock-in type (e.g.: No. 219) may be connected across the
two wire run(s) to the remote control stations instead of on separate wiring
runs to the panel.
Note: If SILENT PANIC ALARM has been selected (see Step 3 above) all
emergency (panic) switches must be connected across the two wire run(s) to the
remote stations. Alternatively, such switches may be connected directly to the
digital communicator as described in the instructions accompanying the
communicator. If switches are connected directly to the panel. audible panic
alarm will result upon their activation.
GROUNDING NOTE:
In regions where the climate is conducive to strong static electricity
discharges, it is recommended that the metal portions of remote stations and
emergency switches be grounded to the nearest cold water pipe (preferred),
electrical (next choice) or telephone ground (last choice) to increase system
immunity to unwanted induced voltages.
Fire Detectors and Sounding Devices: (See Diagram I)
6. a. Run the supervised fire detection loop from terminals I and 2 of the
No. 245-12 to all thermostatt, smoke detectors, combustion detectors or other
fire detection devices to be used. Runs up to 500 feet may be made with f22
wire. Run one continuous loop (no branches) through all devices, connecting
any trouble relay contacts in series with the loop and normally open alarm
contacts across the loop’s two wires. At the last device, terminate the loop
with the 10K ohm end of line resistor (furnished) and a No. 633-12 Supervisory
Module as shown in Diagram I.
Note: Low current smoke and/or combustion detectors such as the Nos.
622-12, 623-12 or No. 6320-12 should be used.
b. I2V. DC power for smoke (Nos. 622-12 or 623-12) or combustion (No. 632D-12)
detectors may be obtained from terminals 3 and 4 of the No. 245-12. Observe
polarity. Use wire sizes in accordance with the following tabulation and
connect the power terminals of the detectors in parallel:
*Use separate power runs of
up to 6 detectors each. Use #I6 wire to the remote reset switch (see Step 6c),
if used.
Note: Do not exceed the ahem and auxiliary total output current limitations
described under SPECIFICATIONS.
c. If a remote fire/panic reset switch is to be used, connect a normall-y
closed, momentary action switch (e.g.: No. 1206) across terminals 4 and 5 of
the No. 245-12. Use wire sizes in accordance with the tabulation shown in the
previous step.
If a remote reset switch is not used, connect .a jumper across terminals 4 and
5.
d. Use terminals 6 and 7 for connection to a 12V. DC fire bell, horn or elec-
tronic siren (observe polarity), If an electronic siren such as the No. 715 is
used, its driver module’s activating signal (fire) will be obtained from
terminals 6 and 7. Driver module power for the speaker may be obtained from
terminals 14 (1-) and 20 (-) on the No. 1023-12 or from an external source.
Instructions accompany the electronic siren. [If an external source is used
for driver module power, cross connect its and the control’s negative (-)
terminals.] Note: Do not exceed the alarm and auxiliary total output
current limitations described under SPECIFICATIONS.
e. Terminals 8 and 9 provide a normally open dry output that closes in the
event of a fire alarm. Connect these terminals as desired, to another
(externally powered) sounding device, or use them to trigger a digital
communicator or tape dialer.
7. Reconnect the panel’s battery and AC power.
TESTING:
I. Arm and disarm the system at each remote station and check the response of
each station’s LED indicator. On tampered stations, check the action of the
tamper switch as well.
Tamper Switch Note: If a tampered station’s front plate is removed, the
station’s tamper switch will close and the alarm bell will ring (the station’s
LED will not light nor can the panel be armed or disarmed). Replacing the
station’s front plate will return arming/disarming operation to normal. The
Fire/Panic reset switch must be used to silence the alarm bell. If SILENT
PANIC ALARM has been selected (see Step 3 above) the alarm bell will not ring
and the day output contacts will not close. Instead, the digital communicator
will be activated. A momentary activation of the tamper function will always
result in a transmission to the central monitoring station, (if a non-delay
channel is used) even if the front plate is then replaced.
The arm/disarm status of the system may be changed by operation of the
panic/tamper circuit. Check the system’s status after resetting the panic
circuit. 2. If a No. 706-12 Mini-Howler (warning horn) is used with the panel,
disconnect the fire loop’s end of line resistor. The No. 706-12 should sound
as long as the resistor is disconnected. Reconnecting the resistor should
silence the No. 706-12.
3. Initiate a fire alarm by blowing smoke into a smoke or combustion
detector. The fire bell or horn should sound and the output contacts should
close (they may be tested with an ohmmeter). Operating the Fire/Panic reset
button momentarily will reset the system and silence the fire signal (if the
smoke has cleared out of the detector and the fire loop has returned to
normal).

TO THE INSTALLER
Regular maintenance by the installer and frequent testing by the user is vital
to continuous satisfactory operation of any alarm system.
The installer should assume the responsibility of developing and offering a
regu’lar maintenance program to the user as well as acquainting the user with
the proper operation
and limitations of the alarm system and its component parts . Recommendations
must be included for a specific program of frequent testing to insure the
system’s proper operation at all times.
