WIRING PROCEDURE
Ensure that all cables are terminated properly.
Conductor insulation should be stripped off
with a bare conductor length of 0.2 inch (5 mm)
minimum and 0.7 inch (18 mm) maximum. Ensure
that cable shield is properly terminated and that
bare shield wire is not allowed to accidentally
contact the metal housing or any other wire.
Use the following instructions when wiring the
U5015 detector:
1. Slightly loosen the three setscrews located
on the retaining ring (see Figure 7).
2. Unscrew the retaining ring to gain access
to the wiring terminals (see Figure 8), and
complete the installation of the system
conduit. Feed the external wiring through
the remaining junction box entry or M25
to 3/4 inch adapter. When installing the
junction box, use care not to damage the
wires and refrain from twisting them.
3. Connect the external wiring to the
appropriate terminals.
– Figure 9 shows the wiring terminals.
– Figure 10 shows the ground lug
locations.
– Figures 12 and 13 show wiring for single
detector configurations.
– Figures 14 and 15 show wiring for multiple
detector configurations.
4. Re-install the assembly. Use the alignment
guide (see Figure 11) to align the retaining
ring with the junction box.
5. Screw the retaining ring on to the junction
box and re-tighten the three setscrews.
