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
the technical 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 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.
-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.
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.).

Wiring

Always disconnect the power supply to carry out wiring.
The wiring between the transmitter / detector / push-button and the station should NEVER be installed in a conduit alongside power, control or supply cables.
For disconnection, the power supply circuit must be equipped with a switch of at least 2 A, 230 V, located near the device. The power supply cable will be H05VV-F or NYM 1x16/3. The section to be used will
depend on current local regulations, but should never be less than 1.5 mm .
Cables for wiring the relay contact should have the relevant section for the device to be connected
The 120 / 230 V~ wiring area must be kept clear of any other external element.
Certain international standards indicate that alarm power supply should originate from a different circuit to that used for the refrigeration and ventilation system. Be sure to comply with current local
regulations.
