Installation & Operation Manual

Maintenance

To keep your control panel in good working order - follow these basic principles;

Remove any dust/debris from the outer enclosure regularly using a slightly damp cloth.



Never spray air fresheners, hair spray, paint or other aerosols near gas detecting devices.



Never paint the device.



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.

What is a Gas Response Check?

Response checks are often referred to as a 'BUMP TEST'. Bump tests are important to make sure a gas

detection device is able to detect a release of gas as early as possible.

The aim of the bump test is to make sure a gas detector is working at its optimum by briefly exposing the

unit to a known concentration of the target gas that exceeds the highest alarm point. If the detector goes

into alarm and all system outputs/relays activate, then it is working safely.

If the system fails to operate as intended in an alarm state, the gas detector must not be used until a full

inspection and service has been conducted.

Why is it important?

A detector may visually appear in good working order, but its sensitivity can be inhibited by external

factors. Dust, humidity, temperature fluctuations, cleaning products, contaminants or sensor drift

(ageing) can cause a decline in sensitivity and eventual failure.

Regular bump tests are important to make sure the detector is able to detect a release of gas as early as

possible.

How often should I Bump Test a detector?

Regular bump tests are important to make sure the detector is able to detect a release of gas as early as

possible. A bump test usually takes seconds (gas type dependant) and is often completed alongside a

scheduled fire alarm test, however the frequency should be determined following a risk assessment by

the end user. Remember, bump testing does not remove the need to have gas detectors inspected,

calibrated and serviced periodically by a trained personnel.

What equipment do I need to perform a Bump Test?

Contact your AGS representative for details of suitable bump testing kits and gases.

Kits usually consist of a certified gas cylinder; flow control regulator, tube pipe and applicator cone.
