Function/Description

IN1+, IN1-
These terminals connect to the 12 or 24VDC FACP notification appliance circuit outputs.
IN2+, IN2-
(Class A or Class B) Input trigger voltage is 9-30VDC @ 5mA min. Terminal polarity is
shown in alarm condition. During an alarm condition these inputs will cause the selected
outputs chosen to drive notification appliances. The designated outputs are set by output
switches OUT1 through OUT4 (Input/Output Selection Table pg. 4). A trouble condition
on an output loop will cause the corresponding input to trip the FACP by opening the FACP
loop. An alarm condition will always override trouble to drive notification appliances.
RET1+, RET1-
For Class A hookups these terminal pairs return to FACP NAC1 and/or NAC2. For Class B
RET2+, RET2-
hookups the FACP EOL resistor from the NAC1 and/or NAC2 outputs are terminated
at these terminals. Optionally, other notification appliances or additional signaling circuit
power supplies may be connected to these terminals. If this option is chosen the EOL
resistor must be terminated at the last device.

Notification appliances are connected to these outputs (Typical Application

be connected in parallel for a maximum NAC output capability of 4 amp. Total supply

current is 6.5 amp. Outputs are controlled by designated input 1 (IN1) or input 2 (IN2)
(Input/Output Selection Table pg. 4).

-- AUX+
This separate 1 amp auxiliary output is typically used to power 4-wire smoke detectors.
It can be reset (voltage drops out) by pressing the momentary aux reset switch on
the AL600LGK logic board or via the N.O. “REMOTE” C terminals (Fig. 4, pg. 7).
