Installation
Typical Location & Positioning
Consider the coverage required and function of the area. Emphasis should be placed on airflow patterns and correct
placement, not perceived detecting ranges. The target gas will only be identified when contact is made with the
sensing element itself. Your monitor should be installed in populated areas that risk high concentrations of CO
2
gas or
varied temperatures e.g. educational and government buildings including laboratories and commercial kitchens.
Take in to account the design of the airflow within the zone area. Avoid conditions such as; condensation; vibration;
extreme temperatures and draft zones. Avoid conditions of any other environmental factors that could potentially
impede the accuracy and operation of the detectors such as; condensation; vibration; extreme temperatures,
pressure, presence of other gases, electromagnetic interference and draft zones. Avoid positioning near draft areas
(windows and door entrances). Where possible, monitors must be fixed in such a position as to allow natural air
circulation. These recommended heights may vary based on airflow and temperature conditions in addition to the
proposed application and location.
Laboratories/educational buildings: Seated head height
Commercial kitchens: 1700mm (5.6ft) from ground level
Multiple monitors may be required to adequately protect property and/or persons!
Access & Mounting
The monitors are designed for surface mounting and must be installed by a licensed, insured contractor or competent
person. A deeper back enclosure is supplied to accommodate wiring where required.
Carefully remove the rear cover from the unit by releasing the two latching clips located at the bottom of the case. To
do this – use a small flat head screwdriver.
Using the rear cover - mark the screw holes to the wall and ensure the wall surface is flat to prevent base distortion.
There are two pre-fractured areas for cable entry provided on the inside of the rear cover, which may be cut away as
required.
After executing the mounting and the connections – replace the rear cover ensuring the two clips are
latched. Make a note of the installation date on the label located on the side of the unit.
