Four-Wire Smoke Detector/Annunciator Power
+ 24 VDC (20.4-26.4, 200 mV ripple), 200 mA max.
Filtered, regulated and resettable*. Power-limited but
when used for four-wire detectors, must be supervised
-
by a UL listed Power Supervision Relay. Power run to
ACS Annunciators is inherently supervised.
+
Notification Appliance power
+ 24 VDC power-limited, RMS-regulated, non-
resettable, 2.0 amps (in alarm) max. Power is super-
vised by output module (such as an ICM-4). Not for
-
annunciators!
CAUTION: The +24 VDC provided on TB2 Terminal
3 is power-limited only when used with the minus
return on TB2 Terminal 4. Do not use the minus
return on TB2 Terminal 2 with the +24 VDC power on
TB2 Terminal 3.
27.6 VDC, 6.5 to 17 AH. Supervised and power-
limited. Fast charge =750mA max., trickle charge =
