English
RED WARNING LAMP (  ) :detector in alarm status. An acoustic warning
signal is issued at the same time and the relay switches after 30 seconds (if the
alarm condition remains).
•
Alarm status
: when the concentration of gas in the room where the detector
is installed exceeds the safety threshold, an acoustic and light warning signal
is activated (red warning lamp
 ); the relay switches if the alarm status
continues for more than 30 seconds. The acoustic and light warning signals
remain active until the gas concentration returns within the safety limits (or the
power supply is cut off).
•
AVOID
getting the detector wet or subjecting it to shock (during normal
household cleaning operations, for example)
• the device may control a normally open (NO) or normally closed (NC) solenoid
valve to cut off the combustible gas
• The device is calibrated to intervene before the concentration of gas reaches
the L.L.E. (lower limit of explosiveness: 5% for methane, 1.8% for butane, the
main component of LPG), that is, before the concentration creates a risk of
explosion.
•
In the event of alarm:
: switch off naked flames, close the gas tap or the
cylinder, do not switch on lights or, activate electrical equipment.
Open doors and windows, identify the cause of the alarm and eliminate it.
If it is not possible to identify the cause of the alarm, leave the room and call
the emergency services
• Alarm thresholds
RGM
: 8% of the L.L.E. for methane
RGG : 8% of the L.L.E for LPG
CLEANING
• Attention: Clean up the cap of the device with a dry, soft, not abrasive cloth.
Don’t use dissolvent, polishing and detergents because they could influence the
reliability of the device.
CAUTION:
May happen to smell gas before alarm takes ON, this is normal; it may happen
according to where detector is located; in fact gas detector react according to
gas concentration on the room.
