OPERATION
HEATING PERIOD
When the detector is fed, a heating period for the sensor starts, necessary for it to stabilize and carry
out the correct measure of the METHANE level in the environment. This cycle takes 120 seconds and
it is shown through the flashing and alternate activation of red light indicators for ALARM and orange
indicators for FAILURE.
When this cycle is finished, for correct operation of the detector, only the red indicator for FEEDING
should be lit continuously.
STANDBY STATE.
This state is shown through fixed lighting of the feeding green indicator. The detector analyses the
METHANE gas concentration in the environment every 100 milliseconds, its state is updated when
modifications are produced.
FAILURE STATE.
If the detector shows any type of anomaly, stopping correct operation, the orange indicator for
FAILURES is activated in a continuous way.
PRE-ALARM STATE.
When the level of METHANE gas concentration is over 10% L.I.E., the detector activates (1 time per
second) the acoustic alarm and the red indicator for ALARM in an intermittent way.
ALARM STATE.
If the pre-alarm state is confirmed for 10 consecutive seconds, the detector goes to alarm state,
activating the acoustic alarm and the red indicator for ALARM in a continuous way.
If required, the acoustic alarm can be silenced by pressing the SW1 pushbutton placed inside the
detector.
OPERATION RELAY ACTIVATION
Operation relay activation is produced 8 seconds after confirming the alarm state.
DETECTOR REPLACEMENT.
In case of ALARM.
1. Extinguish the flames.
2. Cut off the gas supply from the gas main control.
3. Do not turn the lights on or off, or any electric unit.
Open the windows for ventilation. When the alarm stops, the reason for the alarm to be activated is
to be determined and measures are to be taken. If the alarm continues on, and the is no apparent
cause for the leak and/or it can not be repaired, vacate the place and IMMEDIATELY NOTIFY the
emergency service from a safe place. Gas detectors are accuracy instruments.
