Fire legislation in most European countries now states any power supply performing a mandatory function of a fire alarm system must comply with EN54-4/A2. 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.

Context Plus range of cost-effective, third-party approved EN54-4 switch-mode power supplies include a host of user and installer friendly features, as detailed below.

Five boxed 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. ‘Caged’ and ‘PCB only’ versions are also available for use with OEM equipment.

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