Detector heating time
After receiving the electrical power supply, the gas detector needs a heating time of around 5 minutes,
during which it will NOT detect leaks. This time is indicated by means of a quick flashing of the green led
on the detector itself.
Self-diagnosis function
The unit incorporates a self-diagnosis system of the detector and the wiring between the detector and alarm station.
In the case of malfunction, the station will alert making three consecutive tones every 2 minutes, and activating the
visual alarm and the detector status led, while the detector will alternately activate its status leds.
7.- Maintenance
Clean the surface of the equipment with a soft cloth, water and soap.
Ÿ
Do not use abrasive detergents, petrol, alcohol or solvents, as this might damage the sensor.
Ÿ
AKO guarantees the correct operation of the detectors during the first 3 years from the date of purchase,
Ÿ
and after this time, it is advisable to replace the detector.
We recommend changing the detector in the event of having been exposed to high gas concentrations.
Ÿ
The correct operation of the detector should be checked at least once a year, ask about if
your current local regulations require lower intervals.
This check consists of exposing the detector to a small gas concentration and check that
all the relay indications and outputs work correctly.
