The 24V 3A power supply unit (PSU) from C-TEC is ideally designed to independently power any auxiliary device that performs a mandatory function of your fire alarm system. These include Automatic Opening Vent (AOV) systems, auto-dial communicators, aspirating smoke detectors, beam detectors, sounder systems, and related third-party equipment.
The switch mode BF562-3 PSU is IP30 rated for interior use and VDS certified to EN54-4 standards. And the fact that its charging circuit dissipates just 0.35W compared with the industry norm of 2.55W, making the 24V 3A PSU an environmentally-friendly alternative to other PSUs.
The 24V 3A PSU from C-TEC has multiple compelling features. A robust metal cover which serves to protect the electronics. Three LED indicators – green, amber, and red – that display the status of the PSU – supply present, general fault, and auxiliary fault. Plus, EN54 compliant reporting of battery impedance faults. And a single-pole volt-free changeover relay that switches for any fault condition.
What’s more, the BF562-3 PSU can take a maximum of two 12V 18Ah SLA batteries for those instances where ensuring you have a backup power supply is a concern. Its deep discharge protection and link selectable charging capacity further help to prolong the life of the battery.
