WIRING—
The PointWatch Detector has five
22 AWG wires, 20
inches long for wiring into a termination box, FlexVu
UD
10 or the Infiniti U9500.
Red = + 24 Vdc
Black = – (common)
White = 4–20 mA signal output
Yellow = Calibration input
Green = Chassis ground
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.
OPERATING TEMPERATURE RANGE—
–40°C to +75°C (–40°F to +167°F).
STORAGE TEMPERATURE RANGE—
–55°C to +85°C (–67°F to +185°F).
HUMIDITY (Non-Condensing)—
0 to 99% relative humidity (Det-Tronics verified)
5 to 95% relative humidity (FM/CSA verified).
RFI/EMI PROTECTION—
Operates properly with 5 watt walkie-talkie keyed at 1 meter.
INGRESS PROTECTION—
IP
66.
ENCLOSURE MATERIALS—
Aluminum (clear anodized) enclosure and weather
protection baffles. Content: 0.8% to 1.2% Mg, 0.15%
to
0.40% CU.
Stainless Steel (316 electropolished) enclosure,
polyphthalamide (PPA) weather protection baffle.
DIMENSIONS—
See Figures 3 and 4 for the dimensions of the PointWatch
Detector.
WARNING
Always ensure that the detector/termination
box hazardous (classified) location ratings are
applicable for the intended use.
PointWatch Termination Box (PIRTB)
INPUT VOLTAGE—
24 Vdc nominal. Operating range is 18 to 30 Vdc.
POWER CONSUMPTION (Watts)—
0.5 Watts Maximum
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 UD10, and Infiniti U9500 come standard
with M25 threads, and may require a reducer when used
with the PointWatch Detector).
PointWatch Detector thread options:
• 3/4 inch NPT
• M20
