The HAES 5A EN54 Power Supply (PSU-1003) is an EN54-4 approved power supply unit for fire alarm applications where approved power is required but devices are not powered directly from the fire alarm control equipment, such as beam detectors, aspirating detectors and flame detectors.
It can also power sounder circuit controllers and expanders, control panel repeaters, remote communicators and other fire system critical loads. It has dual supply outputs, a failsafe fault relay output and supply healthy and fault LEDs as standard, and houses 2 x 18Ah batteries.
