Altronix AL1042ADA220 NAC Power Extender Installation Guide

Altronix AL1042ADA220 NAC Power Extender

Overview

Altronix AL1042ADA220 is an extremely cost-effective 10A remote power supply/battery charger. It may be con-nected 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 electronically regulated and filtered 24 volt power to Class B, Style W, X, Y or Class A, Style Z NAC loop circuits. Additionally, a separate 1A auxiliary output for 4-wire smoke detectors is available. The 10A 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, X, 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.

The green input LEDs will be off (normal condition).
To reset the memory depress the reset button located on the AL842LGK logic board (Fig. 2c, pg. 7).
The LED(s) will extinguish.
Note: When indicating circuits have restored, trouble memory reset is not required for normal operation.

Optional Hookup Diagram

Optional Hookups

1. Battery and AC monitoring: AC or Battery Fail condition will cause the common trouble input [C “FAULT” NC] to report back to the FACP via Input 1 and Input 2. The common trouble input may also be used for other optional supervisory monitoring.
   To report AC and Battery Trouble connect the battery and AC fail relay output to the common trouble input (Fig. 2).

2. Dry contact input [C ”DRY1” NC] [C ”DRY2” NC] can be used to alarm output from an addressable module (these inputs are unidirection and cannot report back to trigger module).
   Note: If common trouble input, terminals marked [C “FAULT” NC] are not used, these terminals must be shorted (together) to remain inactive (For optional hookups see Fig. 2).

3. Auxiliary outputs provide 24VDC at 1A max per output.
   “AUX1” will be automatically disabled during power failure. (use this for non required backup power)
   “AUX2” will remain operational during allowable power failure. Refer to stand- by chart for stand-by and alarm current.
   Note: If common trouble input, terminals marked [C “FAULT” NC] are not used, these terminals must be shorted (connect jumper) to remain inactive. For optional hookups see Fig. 2b, pg. 7.
