This versatile PSU meets the needs of all fire alarm systems, which must be supplied with power by EN54-4 compliant power supplies. Features include: Universal mains voltage input; Intelligent, two-stage, temperature compensated battery charging for optimised battery service life and performance; Low battery shut off facility that prevents deep discharge and damage to expensive battery packs; and battery circuit impedance monitoring that ensures specified voltage will be supplied when demanded from batteries.

The unit charges up to 45Ah 24V batteries, has regulated DC output, volt-free changeover contact for fault common indication, plus a facility for individual fault outputs to be extended to other systems. There is a dual output option for compliance with EN54-4 clause 6.4.

The K25800 range can provide substantial power for all other parts of fire alarm systems or any other system requiring a 24V DC battery backed power supply. The range is available in a wide range of enclosures designed to match Kentec fire control panels.
