C-TEC BF562-3 power supply, Junction Box Mount, Surface Mount

C-TEC BF562-3 is a power supply from the 5 range.

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 BF562-3 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. It is important to note changing the PSU's parameters in this way is outside the scope of EN54-4 and any changes must be tested by the responsible person for correct operation.

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 BF562-3 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. DATA PORT

Data on the BF562-3's status can be extracted from the PSU's bi-directional data port. The data available includes thermistor measurements; battery terminal voltage; system voltage at load terminals; battery charge current; load current; battery impedance and ASCII text string status messages. Extracting this data requires additional equipment and permissions - contact C-TEC for details.

Key features
