２．Handling
２−１ Before Initial Use
On detecting a toxic gas leakage, this unit show the gas concentration on the LCD and outputs
the gas concentration value in 4-20mA to the indicating alarm unit. When the concentration
exceeds the preset level, the alarm contact activates.
In view of its duty, the gas detector must always be in the normal operation with the power
supply ON. Therefore, it is essential to confirm its operation daily.
For the operation confirmation, refer to 4-1, Inspection Frequency and Items.
This detector may also be sensitive to gases other than objective gas. When the
detector detects the gas and issues alarm, find out whether this is caused by the objective
gas or other gases not covered by the detector.
