Installing the dome
There are a variety of domes and housings. The interlocking clips and safety cables may vary, but all domes
have them.
To attach the dome to the housing, see Figure 19 on page 31 and do the following:
1. Fasten the dome safety cable to the housing’s safety clip.
2. Swing the dome up to the housing and align the dome’s screws with the housing’s dome screw holes.
If you are installing a plastic pendant-mount housing, there are alignment guides on the housing ring
that straddle the rear-facing screw hole of the dome ring.
3. Use the following guidelines for tightening the dome screws.
• If you are installing a plastic pendant-mount or flush-mount housing, the dome screws are self-
locking, quarter-turn captive screws and
require only a quarter turn to tighten .
• If you are installing a flush-mount housing, the dome ring contains a foam pad that requires you to
push up while turning the screws.
• If you are installing the dome on a rugged vandal-resistant housing, the screws are tamper-resistant
and require the provided security torx-pinned bit for tightening. Do not tighten these screws to
more than 17 lb. inches (192 cNm) in torque.
4. Clean any fingerprints off of the dome. See Cleaning the dome on page 36.
CAUTION: To prevent damage, do not touch the dome with your bare hands, do not place the dome face down on any
surface, and protect the dome from dust. Oil and acid residue from your hands can etch some dome
surfaces and is difficult to remove. Use a scratch-resistant cloth or gloves when handling the dome.
CAUTION: Do not use a power drill with the self-locking, quarter-turn captive screws. A power drill can strip the heads
of the screws or the inside of the screw inserts (in the housing) enough to necessitate replacing the housing.
