WIRING—
The PointWatch Detector has five
22
AWG wires,
20
inches long for wiring into a termination box, FlexVu
UD

Power Wiring:
18
AWG minimum is recommended for
power wiring. Larger diameter wire may be required
to maintain a minimum of
18
Vdc (including ripple) at
the sensor for all operating conditions (see Figure
2
).
For maximum EMI/RFI protection, shielded cable is
recommended.

MOUNTING—
The Det-Tronics Termination Box, Model PIRTB, is
recommended for optimum ease of installation and
calibration of the PointWatch Detector. Depending on the
specific application, the detector can be threaded into
any Det-Tronics approved termination box. (Termination
box spacers may be required for flush mounting. The
PIRTB, FlexVu UD
10
, and Infiniti U
9500
come standard
with M
25
threads, and may require a reducer when used
with the PointWatch Detector).
