MOUNT THE DETECTOR
Using three No. 8 flat head screws (or equivalent)
placed through the counter bored holes in the
detector flange, secure the detector junction box
to the surface location.
WIRING CABLE REQUIREMENTS
Always use proper temperature rated cabling
type and diameter for input power as well as
output signal wiring. 14 to 18 AWG shielded
stranded copper wire is recommended.
The field wiring terminal connections are certified
for a single wire in size from 0.2 to 2.5 mm
2
(or
two conductors with same cross section 0.2 to
0.75 mm
2
). The screws must be tightened down
with a torque 0.4 to 0.5 N•m. The metal housing
must be electrically connected to earth ground.
A minimum of 12 Vdc must be present at the
U5015 to ensure proper operation. The maximum
cable length from power source to U5015 is 2000
feet. When the U5015 Smoke Detector is mounted
remotely using an STB termination box, maximum
cable length from U5015 to STB is 500 feet.
WARNING
For field connections, use wires/cables that
are rated at 20°C greater than the maximum
ambient temperature.
NOTE
In applications where the wiring is
installed in conduit, dedicated conduit is
recommended. Avoid low frequency, high
voltage, and non-signaling conductors to
prevent nuisance EMI problems.
JUMPER
Depending on the wiring option that is used,
jumpers may be required. See Table 3 for the
Jumper Usage Guide and Figures 12 to 15 for
wiring examples.
