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. 12V SECURITY STU USED PURELY FOR FIRE ALARM SIGNALLING\u003c\/p\u003e\n\u003cp\u003eThe BF560-12 can help combat an area of fire alarm system non-compliance that is often overlooked - their connection to remote monitoring centres via 12V security STUs or autodiallers. Fire systems that require such monitoring are typically connected to 12V security STUs. Unfortunately, PSUs used to power these STUs normally only offer 12 hours standby, are not connected to a dedicated mains supply and do not include the features demanded by EN54-4 (such as battery impedance monitoring, temperature compensated charging, CPR compliance, etc).\u003c\/p\u003e\n\u003cp\u003eThe BF560-12 solves these problems by allowing the use of 12V STUs with a cost-effective EN54-4 compliant PSU thereby facilitating compliance with BS5839-1 (or European equivalents). To further assist this application, an optional STU mounting plate is available for inside the BF560-12 (order code BF360SP). PSU STATUS LED (located on the PSU PCB)\u003c\/p\u003e\n\u003cp\u003e1 flash = Mains Failure. 2 flashes = Battery Voltage Low. 3 flashes = Battery Voltage Critical.\u003c\/p\u003e\n\u003cp\u003e4 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).\u003c\/p\u003e\n\u003cp\u003e7 flashes = Battery Resistance Fault (Level set by DIP Switch 2 position). 8 flashes = Output Over Voltage. BATTERY FAULT MONITORING\u003c\/p\u003e\n\u003cp\u003eThe BF560-12 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.\u003c\/p\u003e\n\u003cp\u003eIf a degraded battery is fitted, a fault will be shown by the PSU as mandated by EN54-4\/A2. EN50131-6 (POWER SUPPLIES FOR INTRUSION \u0026amp; HOLD UP ALARMS) CAPABILITY\u003c\/p\u003e\n\u003cp\u003eThe power supply inside the BF560-12 has all the electrical functions required to comply with EN50131-6 Grade 4 (which includes Grades 3, 2 and 1). However, the BF560-12's enclosure is not designed to comply with the standard's requirements to trigger an alarm if someone tries to force the box open. OEM security companies interested in utilising the BF560-12's PSU PCB inside their own EN50131-6 compliant tamper-resistant enclosures should contact our marketing department for further details on costs and approvals.\u003c\/p\u003e\n\u003cp\u003eDATA PORT\u003c\/p\u003e\n\u003cp\u003eData on the BF560-12'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.
