3.0 Mounting
3.1 Mounting the
F220-B6RS/B6/B6R/B6C/B6E
Detector Bases
1. Follow NFPA-72 guidelines for mounting locations.
2. Release the base skirt from the mounting base. Use
a screwdriver on the outer edge to release two of
the four fixing clamps.
3. Pre-run all system wiring.
4. Mount the base using the two oblong mounting
holes. Fits 4 in (10 cm) square, AB, and single gang
trim plate.
5. Tighten the base to the mounting surface. Do not
over tighten.
Depending on local regulations, you can
surface mount the bases using anchors,
mollies, or wing nuts, or you can mount
directly to 4 in (10 cm) octagonal electrical
boxes and single gang switch boxes.
The electrical box must be large enough to
accommodate the number and size of
conductors specified by the National
Electrical Code or any local Authorities
Having Jurisdiction (AHJ).
