The Altronix AL1042UL2ADA is an extremely cost effective 10 amp voltage regulated 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

provides auxiliary power to support system accessories. The unit delivers regulated and filtered 24 volt power via up to

four (4) Class B, four (4) Class A or combination of Class B and Class A Notification Appliance Circuits. Additionally, a

separate 1.0A auxiliary output with reset for four (4)-wire smoke detectors is available. The 10 amp max. alarm current

can be divided between the four (4) outputs for powering NAC devices. Each output is rated at 2.5 amp 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). An individual

output of 4 amp is achieved by paralleling 2 outputs. In non-alarm condition independent loop supervision for Class A

and/or Class B 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.
