Altronix AL802ADA220 NAC Power Supply Installation Guide

Altronix AL802ADA220 NAC Power Supply

Overview

Altronix AL802ADA220 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 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 1.0A auxiliary output 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). 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.

Hookup Diagram

Optional Hookups:

• 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. (see Power Board Parameter for use of AC Delay, pg. 6) To report AC and Battery Trouble connect the battery and AC Fail relay output shown in (Fig. 2a) to the common trouble input.
• Dry contact input [C “DRY1” NC] [C “DRY2” NC] can be used to alarm output from an addressable module (these inputs are unidirectional and cannot report back to trigger module). Connection to triggering devices must be made within 20 ft. of distance and using conduit for wiring.
• Auxiliary output [– AUX +] 24VDC at 1A max.
• AC Local [NC, NO, C] should connect to the host control panel for local annunciation of the trouble condition.
  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

Maintenance

Unit should be tested at least once a year for the proper operation as follows:

Output Voltage Test: Under normal load conditions the DC output voltage should be checked for proper voltage level (26.2-26.4VDC recommended range).
Battery Test: Under normal load conditions check that the battery is fully charged. Check specified voltage both at the battery terminal and at the board terminals marked [+ BAT –] to ensure that there is no break in the battery connection wires.
Fuses: Check input fuse on the power supply board, replace if necessary. Input fuse rating is 5A @ 250V.
Note: Maximum charging current is 3.2A.
Note: Expected battery life is 5 years; however, it is recommended changing batteries in 4 years or less if needed
