The Haes 5A EN54 Power Supply Unit has been developed to provide a simple to use, robust solution for fire alarm applications where mandatory EN54 part 4 approval is required. This includes applications where detection devices are not powered directly from the fire alarm control equipment, for example; Beam Detectors, Aspirating Detectors and Flame Detectors. Other applications would be powering Sounder Circuit Controllers and Expanders, Control Panel Repeaters, Remote Communicators, or any other Fire Alarm System critical power supply applications. As standard, the PSUs come with dual supply outputs, a failsafe fault relay output, and Supply Healthy and Fault Condition LED indicators.
