Wall or ceiling mounting

The Gas Detector is not approved for use in hazardous rooms.

Preparation and mounting

Remove the housing cover (release the snap-in anchor using a small screwdriver)
Open the cable feed-throughs in the housing base
Screw the housing bottom section into place
Connect the installation and connecting cables
Secure cables with tie-wraps for strain relief and fit the cover

Alarms and LED displays

Green LED : Ready to operate state
Red LED + acoustic signa: Permissible gas concentration exceeded; the alarm is triggered when 20% of the lower explosion limit (LEL) is reached
Red LED + 30 s alarm: Measures when an alar

Gas Detectors should not be installed

in small, enclosed rooms (e.g., in a cabinet or behind a curtain)
directly above a drain or near a fume extractor
near a door or window
in areas subject to high level of humidity, steam or dust

Important notes

Caution! Hazardous voltage! Installation by person with electrotechnical expertise only. Ensure compliance with the appropriate standards, directives, regulations and specifications when planning and setting up electrical installations.

Protect the device against damp, dirt and damage during transport, storage and operation.
Do not operate the device outside the specified technical data!
Only operate the device in a closed housing (distribution unit).

To avoid dangerous touch voltages that originate through feedback from differing phase conductors, all poles must be disconnected when extending or modifying the electrical connections.

Cleaning

If devices become dirty, they can be cleaned using a dry cloth or a cloth dampened with a soapy solution. Never use corrosive agents or solutions. Disconnect the device from the electrical power supply before cleaning.

Maintenance

The gas sensor on the detector must be tested every 6 months by trained specialist personnel using a test gas.
Operating continuously in normal environmental conditions, the device has an expected service life of several years.
However, certain chemicals can permanently damage the sensor.

Never expose the sensor to the following substances or environments:

silicone sprays and adhesives
corrosive environments where there is hydrogen sulfide, sulfur dioxide, chlorine or hydrogen chloride (cleaning agents containing chlorine, descaling sprays)
moisture and condensation
saline atmospheres

In the event of damage (e.g., during transport or storage), repairs should only be carried out by an authorized person.
