10 Reference & Installation Manual
2.11 Fire Circuit
If your security installation requires the use of smoke detectors, define zone 3 as a "24-hour" fire zone; please
refer to section 7.5.
2.11.1 Standard Installation
Connect the smoke detectors to zone 3 as shown in Figure 20. Note that a fire zone must use a
1KW EOL resistor. If there is a line short or if the smoke detector becomes active, whether the
system is armed or disarmed, the control panel will generate an alarm (see Fire Alarm Output Figure
on page 28). If the line is "open", the control panel will send a "fire loop" trouble report to the
monitoring station and trouble indicator, key [11], will appear in the keypad’s trouble display.
2.11.2 UL/cUL Installation
For UL installations, use a 4-wire, latching, smoke detector (System Sensor - Model 2112/
240). To supervise the power supply, install an "end of line" relay (Model MR3). Connect
the smoke detectors and relay as shown in Figure 21. In the event power is interrupted the
relay will cause a FIRE TROUBLE report to be generated (see section 7.5).
To reset (unlatch) the smoke detectors after an alarm, momentarily interrupt power to the
detectors. To do so, verify that the negative (-) of the smoke detectors is connected to a
PGM. Set the PGM for "Timed N.C." (normally closed), and program the PGM to "open"
when any two keys on the keypad are pressed simultaneously. For more information on
programming the PGM refer to section 9. For UL and cUL warnings, refer to the Warnings
section.
EXAMPLE: To program PGM1 to conduct a smoke detector reset when the [clear] and [enter] keys are pressed at the
same time.
Address 039 = [byp] [2nd]
Address 040 = [5] [10]
Address 042 = [2nd] [6]
Address 056 = [10] [10] [4]
It is recommended to connect all 4-wire smoke detectors using a daisy chain configuration.
2.12 Serial Output Connector
The four pin Serial Output Connector is used to connect additional devices such as the 708DVACS communicator, the Esprint
printing module and the SRI-18 PGM Expander Module to the control panel. For serial output connector specifications refer to
section 1.3.
