Servicing & General Maintenance



DO carefully remove any accumulated dust from the outer enclosure once a month.



NEVER spray lighter gas, paint or other aerosols near detectors or monitors.

NEVER paint devices. Paint will seal vents and may interfere with devices.

It is recommended that any detectors connected to the system are inspected and serviced

at least annually from the date of installation for optimum performance and protection.

Avoid exposure of high concentrations of alcohol found in many products, this can damage,

deteriorate or affect gas detectors. For more information refer to your detector manual.
