WATTSTOPPER

OCCUPANCY/VACANCY SENSORS & TIMERS

Power Packs & Auxiliary Relay Packs

.842"

A cost-effective way to power Wattstopper® occupancy sensors.
1.673"

Wattstopper universal voltage power packs consist of a transformer and high-current
relay in one small unit. In addition to a primary high input, power packs have a secondary
output of 24VDC, 114mA which provides operating power to sensors. Upon sensing motion
or insufficient light, sensors electrically close an internal circuit and send 24VDC back to
the power packs or auxiliary relay packs that control lighting systems.

Power Pack Schematics

Ceiling Sensor with Power Pack

Sensor Schematic with
Auxiliary Relay Pack

Power packs should be installed in
accordance with state, local, and
national electrical codes. They are
designed to attach to electrical
enclosures with 1/2 inch knockouts. In
plenum ceilings, power packs should
be installed in approved electrical
enclosures. Most applications require
UL listed, 18-22 AWG, 3-conductor,
class 2 cable for low-voltage wiring.
For plenum rated ceilings use UL
listed plenum-approved cables.
