Notes
• For carrying out operational test, using exclusively the "Gas Test"
cylinder delivered with detector. Do not use gas from lighters as it
damages the internal sensor irreparably
• Do not expose the device to:
- solvent vapour
- perfume vapour, bleach, ammonia, etc.
- glue, colours and silicones vapours
- different gases from those prescribed
3. Installation and operating control
• Check that the plant is fitted with a gas cut-out solenoid valve
and that it is correctly connected.
• Connect the 230 V~ ±10% 50-60 Hz voltage to the terminals L
and N.
The detector runs an approx. 60 s timed PRE-HEATING cycle
during which the solenoid valve and buzzer are inhibited: this
cycle is indicated by both the green LED and yellow LED
ON.
• Once the preheating cycle has terminated, the yellow LED
turns off and the detector is operational.
• To test the device, hold the “VIMAR test gas” canister 01899
vertically with the valve uppermost and the nozzle against the
detector's lower grille.
• Operate the single-dose calibrated nozzle to release the test gas:
the detector will buzz, its red LED will turn ON and, after 20
seconds, it will close the solenoid valve with a repeated pulse
signal every 15 s on terminals 6 and 7 while switching the output
relay contact (terminals 3-4-5)
When the red LED goes out (end of the alarm state), the buzz-
er is switched off, the contact on terminals 3-4-5 is commutated
and the pulses to terminals 6 and 7 cease.
If the operating check is successful, the gas supply will be
switched on again by resetting the solenoid valve manually.
