Overview:
Altronix AL802ADA220J is an extremely cost-effective 8A remote power supply/battery charger. It may be
connected to any 12 or 24 volt Fire Alarm Control Panel (FACP). Primary applications include Notification
Appliance Circuit (NAC such as strobes and horns) expansion support to meet ADA requirements. It also pro-
vides auxiliary power to support system accessories. The unit delivers electronically regulated and filtered 24 volt
power to Class B, Style W, Y or Class A, Style Z NAC loop circuits. Additionally, a separate 1.0A auxiliary out-
put with reset for four (4)-wire smoke detectors is available. The 8A max. alarm current can be divided between
the four (4) outputs for powering NAC devices. Each output is rated at 2.5A max., and can be independently
programmed for Steady, Temporal Code 3 or Strobe Synchronization. All outputs may be programmed for Input
to Output Follower Mode (output will follow input, i.e. March Time Input, March Time Output). In non-alarm
condition independent loop supervision for Class A, Style Z and/or Class B, Style W, Y FACP NAC circuits is
provided. In the event of a loop trouble, the FACP will be notified via the steered input (input 1 or input 2). In
addition, there are common trouble output terminals [NC, C, NO] which are used to indicate general loop/system
trouble. A common trouble input is provided for optional NC (normally closed) devices to report trouble to the
FACP. Two (2) FACP signaling outputs can be employed and directed to control supervision and power delivery
to any combination of the four (4) outputs.
Specifications:
WARNING: To reduce the risk of fire or electric shock, do not expose the unit to rain or moisture.
This installation should be made by qualified service personnel and should conform to all local codes.
