Fire legislation in most European countries states any power supply performing a mandatory function of a fire alarm system must comply with EN54-4 A2 Power Supplies. As such, any power supply controlling a beam detector, auto-dial communicator, aspirating smoke detector, auto-open ventilation system or auxiliary sounder system must comply with this standard.

C-TEC’s range of cost-effective, third-party approved EN54-4 A2 Power Supplies include a host of user and installer friendly features. Five versions are available, four 24V models rated at 1.5A (two types), 3A and 5A, and a 12V 2A model which has an optional STU mounting plate for auto-dial applications.

All five versions are certified to EN54-4:1997/A2:2006 by the VdS or LPCB (as indicated) and are therefore fully compliant with all relevant European directives including the EMC, LVD and CPD (Construction Products) directives.

Optional ‘PCB’ and ‘caged’ PSUs with exactly the same electronics as our certified PSUs are also available from C-Tec.
