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.
Output Programming Selection Table: Outputs must be programmed independently (OUT1 - OUT4) Switch Positions Function ON Input to Output Follower Mode 1 Temporal Code 3 Mode 3 OFF Descriptions Output follows signal it receives from the corresponding input (i.e. FACP Sync module - maintains synchronization of notification appliance circuit). Enables Temporal Code 3 signal generation output. 1, 2 This mode will accept a steady or a pulsing input. A steady output signal will be generated.
*Not to exceed a maximum of 2.5 amp per NAC.
