Testing the System
There is a [TEST] button on the Detector circuit board.
When the test button is pressed and held – the detector will
simulate an open circuit to ensure all systems, alarms,
indications and other external devices operate as intended.
When the test button is released – test sequence will terminate and return to normal operation.
Remember! - Main systems will need to be reset if conducting a live test!
Service & Maintenance
A service screen will intermittently flash every 30 seconds after one year of
service. The detector will still operate as intended during this time.
Contact your supplier immediately.
Keep your detector in good working order follow these basic principles;
DO carefully remove any accumulated dust from the outer enclosure once a month.
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.
Other gases and substances to avoid; Corrosives (i.e. chlorine & hydrogen chloride); Alkali
metals; Basic or acidic compounds; Silicones; Tetraethyl lead; Halogens and halogenated
compounds.
It is recommended testing your detectors with a calibrated gas.
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.
It is recommended that detectors are inspected and serviced at least annually from the
date of installation for optimum performance and protection due to sensitivity drifts.
