smoke detector sends a CleanMe
TM
signal, the control panel will
generate a Zone Fault trouble and if programmed will transmit the
Fire Loop report code to the monitoring station. The trouble will be
cleared if there is no CleanMe
TM
signal for 255 seconds. If an
alarm occurs, the trouble will be cleared until it is detected again.

2.15.3 Smoke Detector Installation (4-Wire)
Connect the 4-wire smoke detectors and a relay as shown in
Figure 11. Recommended: The System Sensor model 2112/24D
smoke detectors. To comply with UL955, the 4-wire smoke
detectors must be installed using 18 gauge wire. In the event
power is interrupted, the relay will cause the control panel to
transmit the Fire Loop Trouble report if programmed in section
[707]. To reset (unlatch) the smoke detector after an alarm, verify
that the negative (-) of the smoke detector is connected to a PGM
as shown in Figure 11. Then program the PGM with the “Smoke
Reset” activation event (see section 10.1 on page 30) to interrupt
power to the smoke detector for four seconds when the [

are pressed and held for two seconds.

It is recommended that all 2-wire and 4-wire smoke
detectors be connected in a daisy chain configuration.
