VII-18
NOTE
Terminals 4 and 9 (shield) are connected
internally, as are terminals 5 and 8 (24 vdc +) and
terminals 6 and 7 (24 vdc –).
6. Re-install the terminal wiring board inside the
junction box.
7. Set the rocker switches on the DIP switch assembly
on the electronic module for the desired address.
Refer to “LON/SLC Device Address Switch Setting”
in the “Switch Setting” section of this manual for
complete information regarding the switch setting
procedure.
8. Re-install the electronic module, ensuring that the
connector is aligned correctly. Tighten the three
captive screws that hold the electronic module in
place.
9. Replace the junction box cover and hand tighten to
ensure proper sealing.
UV Flame Detector
WIRING REQUIREMENTS
Wiring to the UV detector must be between 12 and 18
AWG with a minimum voltage rating of 600 volts rms
and a minimum temperature rating of 125°C. The use of
shielded cable is highly recommended to provide
maximum protection from RFI/EMI interference.
1. Mount the Swivel Mounting Bracket using 1/4 inch
(M6) screws with a length of at least 1 inch (25 mm).
The mounting surface should be free of vibration.
Allow adequate space around the swivel to facilitate
aiming and wiring of the detector. Armored flexible
conduit should be used for the final 3 feet (one
meter) of the cable run to allow for aiming and
alignment of the detector.
2. Attach the detector to the Swivel Mounting Bracket.
3. Disassemble the detector enclosure by turning the
housing cover counterclockwise. See Figure VII-28.
NOTE
If the detector is equipped with a cover locking
device, it must be loosened using a hexagonal
(Allen) wrench.
4. Connect the wires to the appropriate screw terminals
on the detector terminal block. See Figure VII-27 for
terminal identification. Do not ground the shield to
the detector housing. (Tape off the shield and leave
it disconnected.)
5. Remove the UV sensor tube module from its
shipping package. When handling the sensor tube
module, be careful not to touch the sensor tube,
since oil from the skin can attenuate UV radiation,
reducing the sensitivity of the tube.
6. Using the index pin as a guide, install the sensor
module on the detector terminal block.
