COMPATIBLE 2-WIRE SMOKE DETECTORS
24 VDC panel terminals 17 through 28 provides resettable Class B, 2-wire powered zones. For programming purposes the zone numbers are 1-6.
The maximum wire length is 3000 feet using 18 AWG or 1000 feet using 22 AWG. The maximum voltage is 13.8 VDC and the maximum normal standby current is 1.25mA DC. The maximum line impedance for zones 1-6 is 50 Ohms. The maximum short circuit current is 56mA. When using zone expansion modules, use Model 309 3.3k EOL resistors. The compatibility identifier for the zones is A.
Do not mix detectors from different manufacturers on the same zone. The panel views these zones as “Open” while the power is absent.
