Background
Fire pumps, smoke exhaust fans and fire lifts rarely operate, so faults in their supply circuits stay invisible for long periods. Discovering a lost phase or a breaker left open only when a fire occurs is too late.
How it works
Voltage and current signal sensors are installed on the outgoing side of the dual-power transfer switch feeding fire equipment, reporting overvoltage, undervoltage, overcurrent, phase loss and supply interruption to the monitor, which raises an alarm and identifies the circuit.
Key capabilities
- Five conditions monitored: overvoltage, undervoltage, overcurrent, phase loss, interruption
- Polarity-free two-wire bus between sensors and monitor, minimising installation work
- Alarms carry circuit identifiers, locating the fault to a specific board
- Complies with GB 28184-2011 for fire equipment power monitoring systems
