• These multi-output access control power supply/chargers are specifically 

designed for use with access control systems and accessories. These units 
convert a 115VAC / 60Hz input into five (5) individually protected 
Class 2 Rated power limited 12VDC or 24VDC outputs (see specifications). 
Each output will route power to a variety of access control hardware devices 
including Mag Locks, Electric Strikes, Magnetic Door Holders, etc. 
These outputs will operate in both Fail-Safe and Fail-Secure modes. 
Controlled trigger input is achieved through normally open (N.O.) or 
normally closed (N.C.) supervised input or the polarity reversal from an 
FACP (Fire Alarm Control Panel). A form “C” dry output relay enables 
HVAC Shutdown, Elevator Recall or may be used to trigger auxiliary devices.
