Fire Alarm Power Supplies and Communicators


The HPF902ULADA Fire Alarm Power Supply from Honeywell Power Products offers the highest value among power supplies available today. It delivers 9.0 amps of notification appliance circuit power and built-in synchronization for appliances from System Sensor, Gentex, Wheelock, and Faraday. Our design represents the state of the art in fire alarm supplies. Yet for all its sophistication, it is an extremely cost-effective notification power supply. The HPF902ULADA is a 9.0 amp notification power expander that provides its own AC power connection, battery charging circuit, and backup battery space, for use with fire and security controls. It is ideal for powering notification appliances required by the Americans with Disabilities Act (ADA). It contains a built-in ANSI cadence pattern, which can upgrade older control panels that lack cadence capability.
