10. Reattach the circuit board to the UFT base
11. Attach the External Switch (See “Connecting External
Switch” in this manual)
12. Reattach the UFT cover to the UFT base.
Install in an Electrical Box
Use a 4”x4” non-metallic electrical box that is at least 1½”
deep.
Mounting the box on a wall
In this installation method the UFT is mounted in an electri-
cal box attached to a wall. The magnet is installed in the
wall and passes through the box.
1.
Determine a suitable location for the UFT.
2.
Mark where the magnet will be installed.
3.
Drill a 3/4” diameter hole 3/4” deep into the stud or
wall.
4.
Mark where the box will be installed over the magnet.
5.
Mark the box at the location where the magnet will
enter the box.
6.
Drill a 13/16” hole in the box at the magnet location.
7.
Mark where the UFT will be installed on the box.
8.
Verify the UFT reed switch is properly aligned with the
magnet hole.
9.
Mount the box using screws or brads making sure to
align the hole in the box with the hole in the wall or
stud.
10. Push the magnet, magnet side first, through the hole in
the box and into the hole in the stud or wall. The top of
the magnet should be flush with the side of the box.
11. Mount the UFT in the box using velcro strips.
12. Remove the UFT cover by squeezing the cover ends
firmly to release the tab on the cover from the slot on
the UFT base.
13. Attach the External Switch (See “Connecting External
Switch” in this manual)
14. Reattach the UFT cover to the UFT base.
Mounting the box in a wall
In this installation method the UFT is mounted in an electri-
cal box permanently installed in a wall. The magnet is
installed in the box.
1.
Determine a suitable location for the UFT.
2.
Mark the box at the location where the magnet will be
installed.
3.
Drill a 3/4” hole in the box at the magnet location.
4.
Insert the magnet into the hole.
5.
Mark where the UFT will be installed on the box
6.
Verify the UFT reed switch is properly aligned with the
magnet.
7.
Mount the box in the wall using screws or brads.
8.
Mount the UFT in the box using velcro strips.
9.
Remove the UFT cover by squeezing the cover ends
firmly to release the tab on the cover from the slot on
the UFT base.
10. Attach the External Switch (See “Connecting External
Switch” in this manual)
11. Reattach the UFT cover to the UFT base.
Connecting External Switch
The normally open UFT (60-917) should be connected to a
normally open external switch.
Connection Guidelines
❑
Do not use mechanical switches.
❑
Do not use more than 100feet of 18-gauge, stranded or
solid core wire in any wire run.
❑
Do not use more than 6 feet of untwisted wire in any
wire run.
❑
Do not run wires parallel to electrical wires. If you
can’t avoid a parallel wire run, keep at least 18 inches
away from electrical wiring.
Note
If necessary, you may cross electrical wires at a 90
degree angle.
Making the Connection
1.
Make the connection to the external fire detection
device. (See your device’s instructions.)
Important !
A 4.7 k Ohm EOL resistor must be installed
at the fire detection device for proper supervision of the
UFT.
2.
Feed the wire through the hole in the bottom of the
UFT.
3.
Attach the wire to the terminal block. See Figure 2.
Note
It may be beneficial to feed the wire through the
hole before mounting the UFT.
