•
disconnect the power supply,
•
mount the sensor module making sure it is properly mounted (all pins are in the sockets),
•
screw in the sensor cover, if present,
•
mount the detector cover so that the sensor's inlet surface is under the foam seal of the
ventilation element,
•
turn on the power supply.
After turning the power on, the POWER diode in the ASG-2000 detectors should flash for 60s, signalling
that the sensor is heating up and then lighting up continuously.

TESTING DETECTORS.
8.1.
Installation testing.
The ASG-2000 detectors allow you to test the correctness of the installation. For this purpose, hold
down the TEST button until the PWR LED starts flashing. During the test, the relays are released in
sequence as shown in Table 7.

8.2.
Test of the detection function.
Using a suitable test cap at a flow rate of 0.5 l/min, provide the test gas:
•
for ASG-
2003 containing 100 ÷ 200 ppm CO for a time suitable for triggering alarm A1 or A3,
•
for ASG-2001 and ASG-2002 containing> 20% LEL of gas detected until the alarm is triggered.
When detecting a small amount of gas, the POWER diode is permanently lit with short stops every 2.5
seconds, allowing the test to be performed in a shorter time and not subjecting the sensors to a
significant concentration of gas.
