19. GENERAL CONSIDERATIONS
EURODETECTORS O
2
These detectors operate differently from the others: the Alarm Level is upwards -more oxygen- and the Ventilation Level is
downwards -less oxygen-.
2 SPEED VENTILATIONS
A non-programmable general delay retards 15 s the switch from the connection between the 1st and 2nd speed ventilation.
Furthermore, it will retard the switch of disconnection from the 2nd to 1st speed in order to prevent faults in the ventilation
engines.
AUTOMATIC BATTERY FAULT OPERATION
In the event of a power fault 220V AC an acoustic will go off and the display lights in the module lines will switch off to
reduce consumption.
If the fault lasts for a long time, when the battery voltage reaches 9V another acoustic will go off.
If the power fault continues to last, when 8V are reached the module lines will automatically be disconnected: OFF position.
When the power fault is fixed the module lines will automatically be connected with the parameters they had beforehand.
PROTECTING THE DETECTOR POWER SUPPLY IN THE MODULE LINES
The voltage output to supply the detectors in the module lines incorporates a protection fuse that is automatically replaced.
This fuse opens up automatically whenever there is a short circuit on the line or the consumption increases (>1A). Its
replacement will be automatic and retarded when the anomaly causing its behaviour disappears.
