Rack Mountable NAC Power Extender, 4 Class A or 4 Class B Outputs, 24VDC @ 10A, 120VAC, Red Trove1R Enclosure

Altronix R1042ULADA is a space-saving 10A remote power supply/battery charger for fire signaling applications such as Notification Appliance Circuits expansion (strobes and horns) meeting ADA requirements. The rack mount drawer configuration is designed to be deployed where wall space is limited or may not be an option. R1042UALDA may be connected to any 12 or 24 volt Fire Alarm Control Panel (FACP) and also provides auxiliary power to support system accessories. This unit delivers electronically regulated and filtered 24 volt power to Class B or Class A NAC loop circuits. The 10A max. alarm current can be divided between the four (4) outputs for powering NAC devices. All outputs may be programmed for Input to Output Follower Mode (output will follow input). Two (2) FACP signaling outputs can be employed and directed to control supervision and power delivery to any combination of the four (4) outputs.
