The Controls Dual Relay Switch packs provide 24 VDC operating voltage to all low voltage, 24 VDC, Green gate occupancy sensors and day lighting controllers. These switchpacks can be used where two circuits need to be controlled at the same point. A single switch pack can provide power for up to five sensors. Up to ten switchpacks can be connected to one sensor for control of multiple circuits. Isolated contacts may also be used to control HVAC, contactors, motors, etc. The switch pack has three main components: a transformer and two high current relays. The transformer has a primary line voltage input and a secondary low voltage output. The low voltage output, 24 VDC, provides operating power to connected low voltage Green gate occupancy sensors. When an occupancy sensor detects motion, it electrically closes an internal circuit, pulling up the control signal between the sensor and the switch pack. This signals the switch pack to close its high current relays, turning connected loads on. Applications: The switch pack is designed to work with low voltage Green gate sensors which require switchpacks. It cannot be used with sensors designed for use with any other low voltage relay systems. Consult sensor spec sheets for other sensor/relay combinations.
