AKO-52215 Gas detector
Response selector
It defines the detector's type of response and
affects both the reading shown on the indicator
and the activation of the alarms.
Immediate response: The detector
ON
reacts depending on the last
reading obtained.*
Delayed response: The detector
ON ON
reacts depending on the average
value of the last 11 readings.
The interval between readings is 15 seconds, regardless of the position of the selector.
4.- Installation
The wiring between the detector/button and the station should NEVER be installed in a conduit together with
power, control or feeder cables.
WARNINGS
-Sensors supervise a point and not an area. If the gas leak does not reach the sensor, or the
level of concentration in that point does not reach the foreseen values according to the type
of gas (see page 15) no alarm will be activated.
-The alarm and 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 place where the regular presence of people who can alert to the
presence of alarms is guaranteed.
-Neither the alarm or gas detector are suitable for areas classified as potentially explosive.
Work conditions:
-Keep the detector work environment free of chemical agents (solvent, paints, alcohol, cleaning
products, silicone and derivatives, ethylene, etc.).
-Avoid handling refrigerant gases near the detector.
-Avoid installing the detector near products or devices that might give off CO .
-Human breathing near the detector may increase the level of CO and generate false alarms.
-Do not paint the detector or place it near solvents or paints.
-The detector should be installed away from:
Areas where fermentation and ripening processes of products (bread, pizza, fruit, etc.) may occur.
Ÿ
Smoke outlets located in confined spaces or from engines, generators or motorised machinery (fork-

lift trucks, etc.).
Particularly damp areas or with strong ventilation.
