Function/Description

IN1+, IN1-

These terminals connect to the 12 or 24VDC FACP notification appliance circuit outputs. (Class A or

IN2+, IN2-

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] (Output

Programming 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 hookups

RET2+, RET2- 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.

- - AUX1+

This separate auxiliary output supplies up to 1 amp continuous under normal AC powered conditions.

It will be disconnected from its load during AC power failure (Fig. 2D, pg. 7).

- AUX2+

This separate 1 amp max. Auxiliary output will provide up to 1 amp stand-by current for 24 hours and

up to 1 amp in alarm condition. It supplies up to 1 amp continuous under normal AC powered

conditions (Battery Calculation Worksheet, pg. 9).

Note: Unit is equipped with two (2) 1 amp max. auxiliary outputs: "AUX1" will automatically disconnect when

AC is lost. "AUX2" will remain battery backed up during power outage. For loads connected to "AUX2" please, refer

to battery "Stand-by Specifications" above for ratings. When loads are connected to the "AUX1" and or "AUX2" out-

puts during alarm condition, the remaining outputs may, not exceed 10 amp total alarm current.

(example: AUX1 = 1 amp, AUX2 = 1 amp, outputs up to 8 amp).
