Altronix Maximal Series Maximal11 Dual Power Supply Access Power Controllers Installation Guide

Altronix Maximal Series Maximal11 Dual Power Supply Access Power

Controllers

Maximal Series Overview:

Maximal Access Power/Controllers distribute and switch power to access control systems and accessories. They convert a 115VAC 60Hz input into sixteen (16) independently controlled 12VDC or 24VDC fuse protected outputs. These Fail- Safe/Fail-Secure power outputs may be converted to dry form “C” contacts. 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. Units will route power to a variety of access control hardware devices including: Mag Locks, Electric Strikes, Magnetic Door Holders, 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 (16) outputs. All interconnecting equipment must be UL Listed.
