wIRINg REQUIREmENTS
The simplest installation involves installing the sensor
into one of the UD10-DCU openings and connecting
the wiring directly to the CGS interface board.
Sensor Separation
If the installation requires separation of the CGS
sensor and the UD10-DCU Display, the sensor can be
connected to a model STB1 sensor termination box,
and the CGS/STB combination wired to the UD10.
In this case, shielded cable is recommended to help
protect against interference caused by extraneous
electrical “noise.”
In applications where the cable is installed in conduit,
the conduit should not be used for wiring to other
electrical equipment whenever possible. If other
equipment power wiring is run in the same conduit, the
cabling must be shielded.
The maximum allowable distance between the CGS
sensor and UD10-DCU Display Unit is 500 feet, with
connecting cable 16 AWG minimum.
INSTaLLaTION aND wIRINg PROCEDURE
1. Determine the best mounting locations for the
detectors.
2. Install the CGS sensor within the proper opening
in the UD10-DCU or STB junction box. Mount the
device with the sensor oriented vertically and the
opening pointing down. All junction boxes should
be electrically connected to earth ground.
3. Terminate all wiring at the proper terminals. Refer to
the appropriate illustration for details.
4. Double check that all wiring is the proper size and
type and has been installed correctly. Check for
correct operating voltage at the device.
noTe
Do not apply power to the system with the junction
box cover removed unless the area has been
de-classified.
5. Proceed with startup and calibration.
