OPERATION WITH NORMALLY
CLOSED (N.C.) VALVE
OPERATION TEST
Before carrying out the operation test, open the cover under the
three LED lights (Fig. 10) with a flat-headed screwdriver.
Fig.10
When this is done, it is possible to test operation of the instrument
by pressing and holding the little button on the
Sensor module
(Fig. 11) for at least 2 seconds; all the LEDs turn on and the buzzer
and relay output are activated for 5 seconds.
Fig.11
You will then need to re-engage the electric valve connected to the
output of the gas detector (if present).
Fig.9
ROUTINE TESTING
You are advised to ask the installer to give the detector a general
test at least once a year.
IMPORTANT: Do not use pure gas, such as that in a lighter,
directly on the sensor since the sensor could be irremediably
damaged.
ELECTRICAL CONNECTION WITH SEVERAL
DETECTORS:
Connection of two detectors with a single electric valve (Fig. 8-9)
is shown in the diagrams below. It is possible to connect more
than two detectors, repeating the same connections.
