C-TEC 24V 1.5A EN54-4 Switch Mode PSU Part No. BF560-24
- Certified to EN54-4/A2 by the LPCB and VdS (AFNOR pending).
- A powerful switch mode/digital hybrid PSU that can be customised* to suit your exact requirements – see More Information tab for details.
- Plastic cover on PSU PCB guards against touching live parts.
- Includes a single-pole voltfree 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.
- BF560-24/E caged & BF560-24/C PCB-only versions available.
- TYPICAL USESIdeal 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 BF560-24 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 BF560-24 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 BF560-24’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.

Read moreVesda-E VEA-40 Aspirating Smoke Detector
combines VESDA reliability and early warning smoke detection with pinpoint addressability and a variety of annunciation options that truly surpass traditional spot detectors.They use patented air sampling points and multichannel microbore air-sampling with three alarm sensitivity settings for the sampling points. As a
multi-channel, addressable system, the VEA detector is able to divide a
protected space into sampling locations, enabling the localization of potential sources of fire for faster incident response. The detectors are suitable for
protection of areas where pinpoint location of fire events is essential, thus providing ideal fire detection solutions for healthcare, offices, education, retail, prisons and electrical cabinets. A wide range of features provide flexibility, field programmability, enhanced connectivity and reduced total cost of ownership. -
EXD SOUNDER TCB-0017
Read moreThe EXD Sounder has been approved for use in potentially explosive atmospheres and very harsh environmental conditions.
The unit incorporates a three stage alarm option with sixty three tones to choose from which includes four tones that can be recorded or customised by the installer. All tones can be pre-set during installation.
The units also have the ability to be fitted with a telephone initiation function and can be used as the second ring output indicator for telephones when installed in very noisy environments.
The design allows for termination inside the enclosure. The sounder is supplied with a mounting bracket as standard.
