Application
Switchpacks provide 15 VDC operating voltage to all low voltage, 15 VDC, occupancy sensors and daylighting controllers. A single
switchpack 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 switchpack is designed to work with low
voltage 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.

NOTE: The life of some compact fluorescent lamps (CFLs) is shortened
by frequent automatic or manual switching. Check with the CFL and
ballast manufacturer to determine effects of cycling.
