The AL300ULMR from ALTRONIX is a Multi-Output power supply with fire alarm disconnect. It is specifically designed to use with access control systems and accessories. The AL300ULMR converts a 115VAC 60Hz input into five (5) PTC protected Class 2 Rated power limited 12VDC or 24VDC outputs. Each output will route power to a variety of access control hardware devices including Mag Locks, Electric Strikes, Magnetic Door Holders, etc. In AL300ULMR the outputs are operated in both Fail-Safe and Fail-Secure modes. It also controls trigger inputs achieved through normally open (N.O.) or normally closed (N.C.) supervised input or the polarity reversal from a Fire Alarm Control Panel. The AL300ULMR includes a form in which dry output relay enables HVAC Shutdown, Elevator Recall or may be used to trigger auxiliary devices.
