4. Anomalies
4.1 Solenoid valve not connected
If the yellow LED
flashes while the green LED
is on, this indicates that the solenoid valve or load
resistor is not correctly connected to terminals
6 and 7.
4.2 Fault
If the detector's internal sensor malfunctions, the
yellow LED
turns on and stays on. Contact your
installer to have it serviced.
5. Periodical checks
VIMAR recommends that the detector should be checked periodi-
cally using the "VIMAR test gas" cylinder supplied with the equip-
ment. Proceed as follows:
• Hold the "VIMAR test gas" canister vertically with the valve upper-
most and the nozzle against the detector's grille, then operate the
single-dose calibrated nozzle once to release the test gas.
• After a few seconds, the detector will activate the alarm buzzer,
lighting up the red LED
output relay by means of a pulse signal repeated at 15 second
intervals on the terminals 6 and 7 and by commutating the out-
put relay contact (terminals 3-4-5).
When the red LED
goes out (end of the alarm state) the buzz-
er will stop and the contact on terminals 3-4-5 will be switched
off, stopping the pulses at terminals 6 and 7.
After successfully carrying out the operating check, turn on the
gas supply again using the manual reset on the solenoid valve.
Other test methods (e.g. lighters, other gases) can damage the
sensor and/or result in incorrect indications.
