24V Power Supplies for Fire Alarm Systems. Certified to EN54-4 by VdS and EN12101-10 by AFNOR.
A range of power supplies specifically designed for fire alarm systems. Certified to EN54-4 by VdS and EN12101-10 by AFNOR.
The ST Range of power supplies for fire alarm systems or AOV systems. Available in 1A, 2A and 5A versions, capable of charging up to 65Ah batteries. Includes exterior Engineers Diagnostic LED, allowing for faster system diagnosis. Two independent monitored outputs can also be configured as dual power transmission paths.
Features
- 2 Independant 27.6Vdc monitored outputs
- On-demand load-sharing capability supports either rapid charging of high-capacity batteries or brief high-current peak-loads using current diverted from charger
- EN54-4 clause 6.4 compliant “Dual Path” power transmission option when the PSU is used with CIE but contained in a separate enclosure
- Charging capability (EN54-4 and EN12101-10 compliant) to support up to 65Ah batteries (see ‘Output’ table for maximum system load capability calculations)
- Battery Free operation mode available (not EN54-4 compliant)
- Self-resetting battery fuse protection
- No output interruption during automatic switchover between mains and battery power
- Deep discharge protection disconnects battery from load when output voltage falls below 21.6V
- Mains status indicator LED confirms mains input is present
- Battery status indicator LED confirms healthy battery
- Fault indicator LED (Yellow) active on detection of output fault, charger fault and mains failure
- Fault-diagnostic indicator LED assists with identifying cause of fault (visible through Lid)
- Output 1 and Output 2 status indicator LEDs (dual-path and independent mode option)
- Volt-free changeover (SPDT) relays transmit fault output signals (Comprising: loss of mains / battery fault /charger fault / loss of output)
- Optional RS485 serial interface for fault reporting, diagnostics and status indication and panel integration
Technical Information
- Mains input: 195–240V ac
- Operating temperature: -10°C to 40°C at 95% RH
