Power supplies and batteries

To attain a certified fire alarm system all components must be EN54 certified, the European standard for fire alarm systems. As the power supplies and batteries are part of the installation, these need the EN54-part 4 certification. Due to the fact that most system components, like aspirating systems, flame detectors, beam systems and linear thermal cable systems operate at a supply voltage of 24Vdc and these mostly decentralized placed system need enough power, it is often not desirable or possible that these systems are powered directly from the fire panel loop.

SenseTek provides EN54-4 approved power supplies and batteries for fire alarm systems so that your system will continue to operate even in case that the mains would fail. When using these components, you will be able to certify your installation without problems.

The range of EN54-4 power supplies runs up 10A. The availability of fused output module that can be placed in the power supplies makes it possible that one power supply can power several systems, without the risk that the systems will be infected by one unit failing as all units will be secured by a seperate fuse.

Construction
Boxed power supplies are formed from 1.2mm powder coated steel and finished in white; a selection of 24V ac units are available in polycarbonate IP66 rated boxes. Unboxed units are mounted on a 1.2mm galvanised steel chassis. Encapsulated units are class II double insulated.
