Maximal 77FD Access Power Controller distributes and switches power to access control systems and accessories. It converts a 120VAC 60Hz input into sixteen independently controlled 24VDC PTC protected power-limited outputs. The outputs are activated by an open collector sink or normally open (NO) dry trigger input from an Access Control System, Keypad, Push Button, REX PIR, etc. The FACP Interface enables Emergency Egress, Alarm Monitoring, or may be used to trigger other auxiliary devices. The fire alarm disconnect feature is individually selectable for any or all of the sixteen outputs.
