Description/Operation
The switchpack 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 Greengate
occupancy sensors. When an occupancy sensor detects motion,
it electrically closes an internal circuit, pulling up the control signal
between the sensor and the switchpack. This signals the switchpack
to close its high current relays, turning connected loads on.
Applications
The switchpack is designed to work with low voltage Greengate
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.
