3.- Warnings

Transmitters / detectors measure gas concentration at a given point. If the gas leak does not reach the

transmitter / detector, the alarm will not be activated.

Transmitters / detectors cannot supervise areas. If perimeter supervision is required, several transmitters /

detectors should be installed surrounding the area to be supervised.

Thoroughly studying transmitters' / detectors' location is recommended, bearing in mind the areas most

vulnerable to suffering leaks, the type of gas used, the size and shape of the room, air flows, maintenance

work, etc.

Clean the device surface with a soft cloth, water and soap.

Do not use abrasive detergents, petrol, alcohol or solvents, as this could damage the sensor.

The EN-378 and F-GAS international standards require that correct transmitter / detector functioning

be checked at least once per year. Review what current local regulations specify for these cases. Consult

the appropriate verification method in the transmitter / detector manual. Be sure to always comply

with current local regulations.

WARNINGS

-The alarm and the transmitters / detectors should be installed in a place protected from vibrations,

water and corrosive gases, where the ambient temperature does not exceed the value indicated in

thetechnical data.

-The station should be installed in a monitored area, where it is guaranteed that people able to alert to the

presence of alarms will be present.

-Neither the alarm nor the gas transmitter / detector are suitable for areas classified as potentially explosive.

-Transmitters / detectors supervise a point and not an area. If a gas leak does not reach the sensor, or

if the concentration level at that point does not reach the predicted values for the gas type (see

page 3), no alarm will be activated.

Work conditions:

-Avoid handling refrigerant gases near the transmitter / detector

-Do not paint the transmitter / detector or place it near solvents or paints

-Exposure to acetone vapours may cause false alarms.

-The transmitter / detector should be installed away from:

Smoke outlets located in or originating from engines, generators or motorised machinery (fork-lift trucks, etc.).

Areas which are particularly damp or have strong ventilation.
