HIGH BAY EXTENDER MODULE

HBEM3 AND HBEM3W

DESCRIPTION

The HBEM3 Extender Module attaches a High Bay (HB)

Occupancy Sensor Module to the side of a fixture. With the

extender module attached, the HB sensor can be adjusted up

or down to ensure its view is not blocked by the fixture.

MOUNTING

CONNECTIONS

The HBEM3 includes two chase nipples. The short end of

the chase nipples snap into the HBEM3 or other plastic

connection box. The long end of the longer chase nipple fits

into a metal fixture with a standard knockout. If the fixture wall

does not exceed 1mm (0.04”) in thickness, the nipple snaps

into the knockout securely and the internal nut (included) is

not necessary. The included nut should always be used if the

fixture wall is thicker than 0.04” (1mm).
