Important Warning Statements 

Please take the time to thoroughly read these instructions which should be retained for future reference. 
Detectors are shipped pre-calibrated and configured. 
The expected lifetime of a gas sensor is 3-10 years upon initial power up dependant on your target gas and 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 by a competent person. 
Do not apply lighter gas or other aerosols to the device – this will cause extreme damage to the sensors. 
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. 
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 warning is possible provided your alarm is installed and maintained in accordance with this manual. 
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. 
Multiple detectors may be required to adequately protect property and persons. 
This device does not prevent dangerous gasses from occurring or accumulating. 
Actuation of your alarm indicates the presence of dangerous levels of gas.  
The device is not intended for use in potentially explosive atmospheres. 
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.
