IMPORTANT WARNING STATEMENTS 

 

Please take the time to thoroughly read this user’s guide which should be retained for future reference. 

 

 

The expected lifetime of gas sensor elements is 3-10 years upon initial power up dependant on your target gas and other 
environmental factors. 

 

 

The device will display a message to indicate this time and should immediately be replaced. 

 

It is recommended that this device be commissioned upon installation and serviced annually. 

 

Do not apply lighter gas or other aerosols to the device – this will cause extreme damage. 

 

High concentrations of alcohol found in many products may damage, deteriorate or affect the gas sensing elements. 

 

This device is designed to detect the gas type displayed on the screen only from any source of combustion or 

dangerous level. It is NOT designed to detect smoke, fire or other gases and should NOT be used as such. 

 

This device provides early warning of the presence of gas, usually before a healthy adult would experience symptoms. 

This early warning is possible provided your alarm is located, installed and maintained as described in this guide. 

 

Never ignore your device when in alarm. 

 

This device requires a continual supply of electrical power – it will not work without power. 

 

This device should not be used to substitute proper installation, use and/or maintenance of fuel burning appliances 

including appropriate ventilation and exhaust systems. 

 

This device does not prevent dangerous gasses from occurring or accumulating. 

 

Actuation of your alarm indicates the presence of dangerous levels of gas.  
Seek fresh air supply and contact your local gas emergency service should you suspect a gas leak. 

 

This unit may not fully safeguard individuals with specific medical conditions. If in doubt, consult a doctor/physician. 

 

Your product should reach you in perfect condition, if you suspect it is damaged, contact your supplier
