Installation, Operation & Maintenance Manual
MAINTENANCE
Cleaning
Keep your detector in good working order follow these basic principles;
Carefully remove any accumulated dust from the outer enclosure using a slightly damp cloth.
Never use detergents or solvents to clean your device – this may permenantly or temporarily
damage the gas sensing elements.
Never spray air fresheners, hair spray, paint or other aerosols near the device.
Never paint the device. Paint will seal vents and interfere with the device.
High concentrations of alcohol found in many products may damage, deteriorate or affect the gas sensing
elements – such as; wine; deodorants; stain removers; thinners etc.
Auto-Calibration
Our CO
sensors are designed to automatically recalibrate using background CO
2
For maintenance purposes, the device should be exposed to fresh air intermittently to aid with this
process. Inaccuracies that do not resolve over a 24 hour period may require temporary removal of the
device, from site, for an extended exposure to fresh air.
Testing your CO2-TFT
The aim of the test is to make sure the CO2-TFT is working at its optimum by briefly exposing a level of
carbon dioxide to send the device into an alarm state ensuring all system outputs/relays activate, then it is
working safely. If the system fails to operate as intended in an alarm state, the device must not be used
until a full inspection and service has been conducted. To do this, simply breathe near or into the device.
QUICK TIPS
To increase reaction time, cover the escape vents.
Alternatively, enclose the device and apply gas i.e. in an air tight bag or container.
Always give at least five (5) minutes between testing the same unit.
If in doubt, contact your supplier.
