Install on a bracket
Mounting brackets help align the detector to a vertical angle and to correct imperfections
(non-perpendicular angles) of installation surfaces.
Choosing a mounting bracket:
– The B335 bracket allows a vertical pivot range of +10º to -20º and a horizontal pivot
range of ±25º.
– The B328 bracket installs on a single-gang box and allows rotation of the detector. The
bracket allows you to insert the wiring through the black tube section in the center of the
bracket mounting plate and through the back of the detector base.
– The B338 bracket designed for ceiling mounting allows a vertical pivot range of +7º to
-16º and a horizontal pivot of ±45º. The bracket allows you to insert the wiring through
the ceiling cavity and into the detector base.
When using a mounting bracket, pre-drill or tap out all of the mounting holes shown for that
bracket in the following figure.

Notice!
Using a mounting bracket might reduce catch performance.
Always install the detector within the recommended installation height, with or without a
mounting bracket.
Brackets are not investigated by UL.
Brackets are not EN50131 compliant.

Notice!
Do not use the bracket to tip the detector vertically, unless you intend to compensate for a
non-vertical surface. It may cause false alarms or reduced catch performance.
