Definition of Terms
Semiconductor
This is a principle of the sensor installed in the detector.
See "9-2. Detection principle" for details.
Initial clear
Output from the detector head fluctuates for a while after turning on the power.
This is a function to prevent triggering alarm during that time.
Full scale Maximum value of the detection range.
ppm
A concentration unit that means part per million of the combustible gas to be
detected.
Calibration
Adjusts the readings to the calibration gas concentration value by using the
calibration gas.
Zero suppression A function to cut off the specific drifting that the sensor has.
Alarm delay time
A function which temporarily suspends activation to prevent a false alarm
caused by noise from its outside.
INHIBIT
The gas detection function is temporarily suspended during maintenance, etc.
of the detector.
This is also called "point skip", which has the same function.
