-
If the pre-alarm does not activate, check that it has not been cancelled in the alarm station.
- If the pre-alarm or alarm do not activate, try it again releasing gas for a longer time.
-An excessive exposure might reduce the delay between the activation of the pre-alarm and the alarm, and
lengthen the waiting time for their deactivation.
-Remember to press the reset button to delete the alarm log (green button) after checking.
When you have finished the check, remember to turn the delay switch to its initial configuration again,
disconnecting the power supply before using it.
