) METHANE GAS DETECTOR  

AE09/GM , AE09/GM-12 , AE09/GM-24 

 

Microprocessed gas detector, designed according to Regulation UNE-EN 50194, allows for METHANE 
gas detection  (natural or town gas).  
 
The detector is gauged in order to inform about a danger when gas concentration over 10% of the 
Explosive Lower Limit (L.I.E.)

1

 is reached. When the concentration level is lower than 10% L.I.E. 

again, within a particular time, the detector will be reset automatically. 
 
The detector is catalogued as “Type-A device”, as a visual and sound alarm is produced and an outlet 
which can act directly or indirectly on a cutting device and/or other auxiliary devices.  

 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

It is provided with: 
 

Green light indicator for feeding and operation detector.  
Alarm red light indicator. 
Failure orange light indicator. 
Acoustic indicator for prealarm and alarm through piezoelectric buzzer. 
Relay output through tension-free NA, C and NC contacts. 
Internal push-button for operation test cycle.  

 
The detector feeding tension may vary according to the selected model.  
 

AE09/GM 

230V AC 

AE09/GM-12  12V DC 

AE09/GM-24  24V DC 

 
The detector needs to be fed for proper performance. When the detector is fed, 120 seconds are 
needed for warming and stabilization, during such time, the detector is not able to detect the presence 
of METHANE gas.

L.I.E.

 Volumetric concentration of gas or flammable vapour in the air under which a gas explosive atmosphere can not be 

formed.
