cGas Detector Analog Transmitter - Installation Manual
Rev. B | 2021.08
Detector enclosure must be liquid tight type. Any water or physical damage to
the transmitter that occurs from the installer drilling their own installation holes
will not be covered under warranty.
6.5.2 EMI and RF Interference Considerations
All electronic devices are susceptible to EMI (Electromagnetic Interference)
and RFI (Radio Frequency Interference). Our detectors have been designed
to reduce the effects of these interferences and we meet CSA FCC and CE
requirements for these type of devices. However there are still circumstances
and levels of interference that may cause our equipment to respond to these
interferences and cause them to react as if there has been gas detected.
There are some installation procedures that will reduce the likelihood of getting
faulty readings:
1. Locate the detectors and controllers out of the way from normal foot
traffic and high energy equipment.
2.
Confirm the devices are properly grounded using conduit and shielded
cabling.
3. Inform operators and technical staff working in the surrounding area
to be aware of these possible conditions and that two way radios,
Bluetooth enabled devices, cell phones and other electrical equipment
may interfere with the response of the gas detectors.
6.5.3 Mounting Heights (Sensor Dependent)
The sensor mounting height depends on the density of the gas relative to
air. Heavier than air gases should be detected 6 in / 15 cm from the floor,
lighter than air gas sensors should be placed on or near the ceiling, and gases
which have a density close to that of air should have sensors installed in the
“breathing zone” 4 - 6 ft / 1.2 - 1.8 m from the floor. The breathing zone refers to
the area 4 - 6 ft / 1.2 - 1.8 m from the floor, where most human breathing takes
place. This is a good default location for sensors, as many gases are often well
dispersed in air.
