Temporary Weatherproof cover
The back-box is supplied with a cover that pro-
tects the wiring from the weather.
If the top-case is not fitted straight away then fit
the Weatherproof cover to protect the wiring.
This cover does not make the back-box flame-
proof.
Ensure that the O-ring supplied is fitted to the
cover. Securely tighten the four M6 x 20 mm hex
head screws to retain the cover.
Weather hood fitting and removal
The Weather hood is optional and is used to pro-
tect the detector against extreme environmental
conditions such as strong sunlight or torrential
downpour.
The Weather hood can be fitted without having
to completely remove the detector from the
mounting bracket.
