Fire legislation in many countries now states any power supply performing a mandatory function of a fire alarm system must be approved to EN54-4. C-TEC's VdS certified switch-mode power supplies were the first to hit the UK market and are fully compliant with EN54-4 making them ideal for controlling beam detectors, auto-dial communicators, aspirating smoke detectors, electromagnetic door holders, ventilation systems and more. The range comprises 1.5A, 3A and 5A 24V units and a 2A 12V unit. A comprehensive range of non-EN54 certified 12V and 24V PSUs is also available for non-mandatory fire and other life safety applications. Together, the two ranges combine to make C-TEC's power supply offering one of the most comprehensive in the industry.
