Single-loop flash and sound alarm controller

switched input passive contact switched input (normally open/normally closed)level input control signal for acoustics usage, high level signal ≥4 V

switched output ·Output a pair of passive normally open contact switch (which will be closed when alarms), contact action synchronizes with sound alarm                          ·DC level output signal > 4 V                          ·Passive switched output (normally open: which will be closed when alarms)                          ·Contact capacity: 3A/24VDC, 0.7 A/110 VAC resistive load
