What is a Fixed Gas Detection System?
The gas detection head is installed in the hazardous area in order to detect the targeted gas. This data is then transmitted back to the control panel which is situated in the safe area. The data from the detection head can be seen on the LCD screen located on the control panel. The control panel has relays and signal output to Building Management Systems or Programme Logic Controllers, as well as actuate equipment such as, shut-off valves and alarms.
Gas detection heads are positioned depending on the density of the gas. This can be six inches from the floor for heavier-than-air gas, but if the gas is lighter than air the sensor should be mounted close to the ceiling. Gases with a density close to air should be within the breathing zone, usually between four and six feet above the floor. The detection head should be placed in an area with good circulation and not a ‘dead air spot’, where there is little air movement.
