AL842ULADA NAC Power Extender Installation Guide (See Application Guide for additional information) Altronix Corp. 140 58th St. Brooklyn, NY Rev.
AL842ULADA - NAC Power Extender Overview: The Altronix AL842ULADA is an extremely cost effective 8 amp remote power supply/battery charger. It may be connected to any 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.
Power Supply Specifications: AC Input: 120VAC 60Hz, 5 amp supplied by a maximum 15 amp dedicated branch circuit. Output: Four (4) regulated supervised NAC output circuits, 24VDC, 2.5 amp maximum current. One (1) aux. special application 24VDC power output circuit 1 amp, non-supervised total output current must not exceed current 8 amp in Alarm Condition. Battery: Use two (2) 12VDC / 12AH or two (2) 12VDC / 7AH batteries connected in series.
Output Programming Selection Table: Outputs must be programmed independently (OUT1 - OUT4) Function Switch Positions Descriptions ON OFF Input to Output Follower Mode 1 2, 3 Output follows signal it receives from the corresponding input (i.e. FACP Sync module - maintains synchronization of notification appliance circuit). Temporal Code 3 Mode 3 1, 2 Enables Temporal Code 3 signal generation output. This mode will accept a steady or a pulsing input.
Terminal Identification Table: AL842LGK - Logic Board Terminal Legend Function/Description IN1+, IN1IN2+, IN2(Supervised) These terminals connect to the24VDC FACP notification appliance circuit outputs. (Class A, Style Z or Class B, Style W, Y) Input trigger voltage is 8-33VDC @ 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.

AC FAIL NO, C, NC Form “C” dry contacts indicate the loss of AC, with AC present terminals marked [NO and C] are open, [NC and C] are closed. When loss of AC occurs terminals marked [NO and C] are closed, [NC and C] are open.

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 shown in (Fig. 2a) to the common trouble input.
