The Firex low-profile Surface Mount Pattress Model PAT is
required for surface mount installation of Firex smoke alarm
models GC240, I240C, PG240, PAD240. DO NOT use the
PAT with any other smoke alarm models except as
specified above.
Disconnect mains power prior to
starting installation.
1. Locate the most appropriate site for mounting the pat-
tress and smoke alarm. See the User's Manual sup-
plied with your Firex smoke alarm for detailed siting
information.
NOTE: Model PAT has several mounting plate holes to fit
many applications. These include holes for attaching to
standard electrical boxes or direct to a ceiling or wall.
2. Determine the closest electrical cable knock-out for the
site.
a. If your application requires surface mounting elec-
trical cable, mark the best raceway knock-out for
your application.
b. If mounting directly to wallboard, mark the mount-
ing hole locations and drill one (1) hole at each
mark.
3. Using a sharp knife, remove appropriate cable knock-
out. For surface mounting, use pliers to remove appro-
priate raceway knock-out(s).
4. Route mains power supply wires through cable knock-
out or through raceway knock-out.
5. For wall or ceiling siting, insert screw plugs (furnished
with smoke alarm) into the drilled holes. Attach pattress
to the wall or electrical box at mounting holes with two
screws (furnished).
6. Fix green Earth wire from mains supply to EARTH "I"
screw terminal on pattress board.
7. Fix line (or brown)
wire from mains sup-
ply to AC MAINS "L"
screw terminal on
pattress board.
8. Fix neutral (or blue)
wire from mains sup-
ply to AC MAINS "N"
screw terminal on
pattress board.
9. Connect cable for
interconnect to AC
MAINS "I" terminal on pattress board.
10. Fix smoke alarm connector wires to appropriate screw
terminals on the alarm terminal block of the pattress
board. Follow directions outlined in the smoke
alarm User's Manual.
11. Attach mounting plate to pattress by threading two
screws (supplied with pattress) into smoke alarm
mounting receptors.
12. Fix smoke alarm to mounting plate according to the
Smoke Alarm User's Manual.
13. Restore mains power supply.
14. Test unit as outlined in the Smoke Alarm User's Manual
to be sure it is functioning properly.
