General Maintenance
Cleaning
Keep your gas detector in good working order - follow these basic principles;
Remove any dust/debris from the outer enclosure regularly using a slightly damp cloth.
Never use detergents or solvents to clean your device.
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.
Concentrations of alcohol found in many products may damage, deteriorate or affect the gas sensing elements
such as; wine; deodorants; stain removers and thinners. Other gases and substances to avoid are; corrosives
(i.e. chlorine & hydrogen chloride); alkali metals; basic or acidic compounds; silicones; tetraethyl lead;
halogens and halogenated compounds!
Manual Circuit Simulation Test
When the test button on the circuit board is pressed and held the detector will simulate an open circuit to ensure
configured systems, outputs, alarms, indications and other external devices operate as intended in response to gas.
When the test button is released – the test sequence will terminate and return to normal operation.
Access to the interior of the detector, when carrying out any work, must be conducted by a competent person!
This test does not check the gas sensing element itself!
Annual Service Message
It is recommended that detectors be serviced at least annually from the date of installation for optimum performance
and protection due to sensitivity drifts. A service message will appear on the Parksafe control panel after one year of
detector operation. The detector will still operate during this time but contact your supplier immediately.
The annual service message clock will begin after five (5) hours of continuous power irrespective of whether the system is
then used intermittently. To reset it, the unmarked header on the detector board will need to be shorted out.
End of Operational Life (EOL)
The typical life of a gas detector depends on its application and intended target gas, in addition, the operational life
can be prolonged if the system and equipment is installed and maintained in accordance the instructions stated within
this manual. A message on the Parksafe control panel will indicate that a detector has reached its expected
operational lifecycle. This means the gas-sensing module needs to be replaced and the affected Parksafe detector,
the 'Fault' LED will remain illuminated.
The EOL is approximate from the first five (5) hours of continuous power!
The EOL will depend on the type of gas your detector is targeting and may vary depending on its application and
environmental conditions such as the frequency of exposure to the target gas, poisons or inhibitors!
