The detector may be installed approximately 3 ft to 3-H

not obscure the pattern of protection.
The detector and wall plate must be mounted inverted

(the PIR window at the

top)

with the wall plate tilted
forward (downward). Two self-adhesii rubber spacers
have been provided to aid in tilting the wall plate.
It must be noted that although this procedure adjusts
the PIR zones so that small animals wfll not be
detected, a cmwling intruder will ALSO go undetected.

Assemble the two spacers, one abwe the other.
