The NG TFT is a natural gas semiconductor detector and should be mounted in accordance with certain considerations. Do not position next to burners, heaters or ovens where temperatures above the room ambient may be experienced. It is, if possible, better to mount the sensors on the opposite wall. This is, of course, dependent on the size of the protected area. Natural gas is lighter than air and will therefore rise, meaning the sensor should be mounted 10 Inches from the Ceiling of the protected area. The Natural gas detectors at detection will go into alarm at 10% of the low explosion level. When connected to an CGS controller, this can be used to trigger the isolation of the power supply to a solenoid valve and as such isolation of the gas supply. This can then be rectified by resolving the leak, allowing the sensor head to clear and resetting the attached CGS panel and detector.
