C-Tec BF562-1 Switch Mode 24v 1.5A EN54-4 Boxed Metal PSU
C-Tec BF562-1 Switch Mode 24v 1.5A EN54-4 Boxed Metal PSUThe BF562-1 is certified to EN54-4A2 by the LPCB and VdS AFNOR pending. It comes with a plastic cover on PSU PCB which guards against touching live parts. Includes a single-pole voltfree changeover relay that switches for any fault condition.Key FeaturesMultiple indicators - supply present general fault fault type aux. equipment faultTwo selectable battery charge currentsBattery fault impedance limits can be optimised to suit load current helps extend battery lifeMains fail simulation modeImproved on-board temperature sensor with optional remote sensorElectronic functions comply with EN50131-6 grades 1-4 for security applicationsBF562-1E caged BF562-1C PCB-only versions availableTYPICAL USESIdeal for poweringbeam 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 CUSTOMISATIONThe BF562-1can 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 configurableInputOutput settings. It is important to note changing the PSUs parameters in this way isoutside the scope of EN54-4 and any changes mustbe tested by the responsible person for correctoperation.PSU STATUS LEDlocated on the PSU PCB1 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.8flashes Output Over Voltage.BATTERY FAULT MONITORINGThe BF562-1 complies with EN54-4A2 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 andor distribution degrade leading to increased internal resistance. If a degraded battery is fitted a fault will be shown by the PSU as mandated by EN54-4A2.DATA PORTData on the BF562-1s status can be extracted from the PSUsbi-directional data port. The data availableincludes thermistor measurements battery terminal voltage system voltage at load terminals battery charge current load current battery impedanceandASCII text string status messages. Extracting this data requires additional equipment and permissions - contact C-TEC for details.
