Fire Zone Wiring: 2-wire Smoke Detectors
If PGM 2 is programmed for 2-wire smoke detector connection, the detectors must be wired according to the following dia-
gram:
Figure 2-16 2-Wire Smoke Detector Wiring
Note: Additional 2-wire smoke detectors must be connected in parallel as shown above. The maximum number of smoke
detectors on a 2-wire loop is 18.
Note: Do not combine smoke detector models from different manufacturers on the same circuit. Operation may be impaired.
Refer to the smoke detector installation sheet when positioning detectors.
