CTEC BF562-1 - 24V 1A Switch Mode PSU

A powerful 24V 1,5A switch mode / digital hybrid PSU that can be customised to suit your exact requirements. Plastic cover on PSU's PCB guards against touching live parts. Includes a single-pole volt-free changeover relay that switches for any fault condition.

Multiple indicators - supply present, general fault, fault type & aux. equipment fault. Two selectable battery charge currents. Battery fault impedance limits can be optimised to suit load current (helps extend battery life).

Mains fail simulation mode. Improved on-board temperature sensor with optional remote sensor. Electronic functions comply with EN50131-6 grades 1-4 for security applications. BF562-5/E encased version also available.

TYPICAL USES

Ideal for powering beam detectors, auto-dial communicators, aspirating smoke detectors, auto-open vent systems, auxiliary sounder systems or any other device performing a mandatory function of a fire alarm system.

PSU CUSTOMISATION

The BF562-1 can be customised to suit your exact requirements using a BF423 configurator & PC. Configurable parameters include float voltage temperature compensation, battery charge rate (mA), battery impedance and configurable Input / Output settings.

PSU STATUS LED (located on the PSU PCB)

1 flash = Mains Failure.
2 flashes = Battery Voltage Low.
3 flashes = Battery Voltage Critical.
4 flashes = Charger Failure.
5 flashes = Charger OK (Battery is either actively charging, or in float charge).
6 flashes = No Batteries Fitted (indicating DIP Switch 4 position).
7 flashes = Battery Resistance Fault (Level set by DIP Switch 2 position).
8 flashes = Output Over Voltage.

BATTERY FAULT MONITORING

The BF562-1 complies with EN54-4/A2 and therefore must monitor battery resistance. The fault threshold is directly related to the ability of the battery to deliver the rated current to the load. For example, batteries stored uncharged for long periods, during shipment and/or distribution, degrade leading to increased internal resistance. If a degraded battery is fitted, a fault will be shown by the PSU as mandated by EN54-4/A2.
