2.11.2 UL Installation
For UL installations, use a 4-wire, latching, smoke detector (UL -
Falcon Model 5454). 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.
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.
EXAMPLE: To program PGM1 to conduct a smoke detector reset
when the [CLEAR] and [ENTER] keys are pressed at the same time.
