Firex PAT Installation guide

Brand: Firex

Model: PAT

Type: Installation guide

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.

CAUTION

The Firex low-profile Surface Mount Pattress with Relay

Model PATR is required for surface mount installation of

Firex smoke alarm models GC240, I240C, PG240,

PAD240. DO NOT use the PATR with any other smoke

alarm models except as specified above. The pattress

also allows connection to an auxiliary device (horn, door

closer, light, etc.) through a relay control.

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 supplied

with your Firex smoke alarm for detailed siting informa-

tion.

NOTE: Model PATR has several mounting plate holes to fit

many applications. These include holes for attaching to stan-

dard 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 electri-

cal cable, mark the best raceway knock-out for your

application.

b. If mounting directly to wallboard, mark the mounting

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 appropriate

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 AC MAINS "E"

screw terminal on pattress board.

7. Fix line (or brown) wire from mains supply 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 pat-

tress board.

9. Fix auxiliary device

wires to appropriate

screw terminals on

RELAY screw termi-

nals. Follow manu-

facturer’s directions

for wiring auxiliary device to pattress.

NOTE: The relay contacts are non-latching. The relay can be

modified to pulse the output. To do so, cut the “JUMPER”

wire on the pattress board. (See diagram above.)

10. Fix smoke alarm connector wires to appropriate screw ter-

minals on the alarm terminal block of the pattress board.

Follow directions outlined in the smoke alarm User's

Manual (enclosed).

11. Attach mounting plate to pattress by threading two screws

(supplied with pattress) into smoke alarm mounting bracket

receptors. The smoke alarm can be mounted only one way.

Be sure tamper-resist tab points over pattress board

as shown above.

12. Fix smoke alarm to mounting plate according to the Smoke

Alarm User's Manual.

13. Restore mains power supply.
