SSI Low Voltage Sensors: When Will A Low Voltage Sensor Be Operated By 12-24 VAC?

The low voltage sensors can be operated by 12-24 VAC on the red and black wires.  When powered using VAC the control out on the white wire is always DC and is generally only used to connect multiple sensors, not hook into a power pack.

See attached drawings - most often an auxiliary relay is used to provide contact closure (dwg 2.003)  to a control panel or return 12-24 VAC (dwg 2.004) to the control panel.
