CAUTION! The detector has a service life of 5 YEARS from the date of installation. For surface detectors 01895 and 01896, the service life may be extended to 10 years by replacing the sensor after 5 years (VIMAR 01895.G sensor for Gas Stop GPL, VIMAR 01896.M sensor for Gas Stop Metano). The sensor may be replaced one time only and exclusively by a qualified technician. Make sure to fix the plate bearing the replacement date in the space provided on the front of the device (for flush mounting devices) or note it on the label to be stuck on the side of the device (for surface mounting devices), as well as inside the cover of this instruction booklet. Before installation check that the load resistor is fitted inside the detec- tor and that it is connected to terminals 6 and 7 (~ 1 kΩ). When connecting up the VIMAR 16590 solenoid valve or the manually resettable 12 V d.c. 13 W solenoid valves (usually open (NO)), with maxi- mum excitation energy of 0.4 joule, use terminals 6 and 7, removing the load resistor. For connecting other types of solenoid valve and additional alarms, use terminals 3-4-5 with the clean change-over contact output relay and do not remove the load resistor on terminals 6 and 7 (for the relay capacity, refer to the chapter “Technical data” on page 13).ENGLISH - 3

1. Installation Gas Stop

Apply to authorized technicians for all installation and any routine and non-rou-tine maintenance operation as well as for the replacement of the detector at the end of its life-time.The LPG/methane detector must be installed in a position in which air circu-lates freely, at a distance of no more than 3-4 m from boilers, water heat-ers, stoves and gas canisters and at 20-30 cm above floor level (figure 1 - Gas Stop GPL) or 20-30 cm from the ceiling (figure 2 - Gas Stop Metano). 1,5 m min 30 cm max 1 m min - 4 m max 1 m min - 4 m max Fig. 1 Gas Stop GPL For the installer4 - ENGLISH 30 cm max 1 m min - 4 m max 1 m min - 4 m max 1,5 m min 1,5 m min Fig. 2 Gas Stop Metano The LPG/methane detector must not be installed:• air o near • near cookers and other equipment used for cooking• near sinks and water taps• near air vents, windows, ventilators, etc.

• in excessively dry or humid areas• in areas where dirt or dust can obstruct its grilles or sensor• where the ambient temperature exceeds the detector's operating tem-perature limits (–10 °C to +40 °C)• in a closed location (behind curtains, inside cabinets, etc.).ENGLISH - 5 It is possible to connect up more than one detector in the same building (different rooms), controlling one single solenoid valve. In this case, the voltage supply of each detector must be connected up to terminals L and N, respecting polarisation (L with L; N with N) and the outputs for the solenoid valve of each detector must be parallel connected, respecting the numbers on the terminals (6 with 6; 7 with 7). In this way, a gas leak in any of the rooms will cause the gas supply to be interrupted, closing the solenoid valve, while the opti

cal/acoustic warning on the detector responsible for the electronic switch-off pulse will indicate the room where the gas leak has taken place (see example figure 4).

• terminals 3 - 4 - 5: output relay with change-over contact for connection of extra alarm signals and for solenoid valves which differ from the one indicated above (terminals 3-4 if normally closed; terminals 4-5 if normally open) All the solenoid valves must be of the manually resettable type. If the solenoid valve or the load resistor connected to the terminals 6 and 7 are not of the above indicated type, the yellow LED

the detector will be flashes during normal operation to signal the lack of connection; this, however, does not impair the performance of the equipment. For the installer6 - ENGLISH NOTES Idea: code 16591 - 16592 8000: code 08496 - 08497 Surface mounting units: code 01895 - 01896 The 230 V~ power circuit, the 12 V DC solenoid valve output and the clean contact output relay are separated from each other by double insulation. This means that the relay can be connected to either a mains- or SELV-powered solenoid valve and that the 12 V DC solenoid valve output provides SELV power. Surface mounting units: code 01895 - 01896 Surface mounting devices: at the end of the five years, its life may be extended to 10 years by replacing the internal sensor (VIMAR 01895.G sensor for Gas Stop GPL, and VIMAR 01896.M sensor for Gas Stop Metano). The sensor may be replaced no more than once and only by an expert technician. Eikon: art. 20420 - 20421 Arké: art. 19420 - 19421 Plana: art. 14420 - 14421 The 230 V~ power circuit and the 12 V DC solenoid valve output are separated from each other by double insulation. This means that the output provides SELV power. The clean contact output relay is separated by a single insulation. This means that it can be connected to a mains-powered solenoid valve.ENGLISH - 7 For the installer LN 576 43 Gas Stop GPL - art. 01895 Gas Stop Metano - art. 01896

• 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.ENGLISH - 13

Gas Stop GPL and Gas Stop Metano The LPG/methane electronic gas detectors are intended to detect the presence in a room of liquid and LPG gas (Gas Stop GPL) or methane (Gas Stop Metano), in concentrations far below the danger threshold, and to operate the solenoid valve to cut off gas delivery and issue a visual (LED) and acoustic (buzzer) warning. The optical signals are located on the front of the equipment and indicate, according to their state (off , flashing or on ) the operating mode of the detector (as shown in the paragraph “Operations”). The alarm buzzer is inside the detector and sounds to indicate an alarm condition (see “Operation”). Calibration of the sensitivity of the specified value (see ”Characteristics”), for each detector, is set and sealed at the fac

tory, in a special gas chamber. Each detector is supplied with a thermal compensation circuit, in its electronic card, which maintains sensitivity at the calibrated level even when ambient conditions (temperature, humidity) change.

N.B. Refer to “Operations” paragraph for a more detailed expla

nation of the state of the optical signalsENGLISH - 17 For the user Gas Stop Metano

Gas Stop GPL - art. 19421 Gas Stop Metano - art. 19420 Gas Stop GPL art. 01895 Gas Stop Metano art. 0189618 - ENGLISH The command is given by means of a pulse which is repeated every 15 seconds, sent to terminals 6 and 7 and by commutation of the output relay contact (terminals 3-4-5). The pulse is indicated by the yellow LED (flashing during the pulse signal to the solenoid valve). When the red LED goes out (end of the state of alarm), the buzzer is switched off, the contact on terminals 3-4-5 is commutated and the pulses to terminals 6 and 7 stop. It is now necessary to reset the solenoid valve by hand in order to reinstate the normal gas supply.

Once danger threshold 1 has been exceeded (alarm) the red LED turns on, the buzzer sounds and, if the danger condition persists for more than 20 s, the detector closes the solenoid valve and switches the relay.

1. see “Technical characteristics - operating threshold”

3.1 Starting up the detector

When it is switched on, 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.

3.2 Normal operations

Once the preheating cycle has terminated, the yellow LED turns off and the green LED stays on, to indicate that the detector is operational.

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.

If the detector's internal sensor malfunctions, the yellow LED turns on and stays on. Contact your installer to have it serviced. For the user

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

and closing the solenoid valve and 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.20 - ENGLISH

• Do not tamper with or open the device: electric shock hazard, danger of damage to the detector.

• Clean the device only with a damp cloth. Keep the aeration grilles free of obstructions.

• Do not expose the device to: - sprays - cigarette lighter gas - solvent vapour - perfume vapour, bleach, ammonia, etc. - glue, colours and silicones vapours - other gases from that prescribed - direct cooking vapours - etc.

• In order to warn of gas leaks, LPG and methane gases contain an odorous substance. This odour may be noticed before the detector operates, although the latter is calibrated to operate far below the gas explosion threshold.

6. How to behave in the event of a gas leak

CAUTION! In case of an alarm, keep calm and:

• Turn off all open flames and all gas appliances

• Close the tap on the gas meter or on the LPG cylinder

• Do not turn any lights on or off; do not switch on any electrical equipment or devices (compresi i rivelatori di gas)

• Open doors and windows to increase ventilation

• Do not use the phone inside a building in which there is a sus- pected gas leak If the alarm stops the cause must be found immediately and the necessary measures taken. If the alarm continues and the cause of the gas leak cannot be found or eliminated, leave the building and notify the emergency services, once outside.FRANÇAIS - 12 - FRANÇAIS SOMMAIRE Pour l’installateur
