È suitable for detecting the presence of: - LPG - CARBON OXIDE - SLEEPING GASES strong> (ether and derivatives) in anomalous concentration below the danger threshold (LIE) signaling with a visual (LED) and acoustic (BUZZER strong>).

It has 3 LEDs, a test button and an acoustic signal: GREEN LED: power on, it is activated using the sliding lever located next to the; appliance RED LED: GAS presence alarm, it activates at the same time as the acoustic signal YELLOW LED: circuit failure / anomaly TEST BUTTON: tests the functionality of the signaling circuit The heart of the system consists of a Motorola microprocessor and a sensor. Fundamental characteristics of the sensor are low power consumption, high sensitivity and response speed . The installed microprocessor allows a self-diagnosis function of the device and of the sensor; it also allows accurate processing coming from the sensor itself.

The TRIO-GAS is equipped with an open-collector type output which is activated together with the red LED and the acoustic signal, to which it is It is possible to connect a manually reset gas valve or activate other electrical appliances (ventilators, sirens) or connect to any type of burglar alarm. The current capacity is 500 mA and it is more ; which is sufficient if it is necessary to drive an external relay, through which to connect any other load. The output command can be configured as static or impulsive, via a jumper located inside the board.

MODE; OF OPERATION When the device is switched on, the microprocessor first of all carries out a self-diagnosis phase to verify the correct functioning of the sensor, then it will make the yellow and red LEDs flash for about 1 minute, time required to calibrate the sensor. Once the flashing phase is over, the TRIO-GAS is fully functional. POSITIONING IN THE ROOM: The position determines the greater or lesser sensitivity towards the gases.

To obtain an accurate detection and protect yourself from all three types of gas, the Trio-gas must be installed at a height ranging from 50 cm to one meter from the floor, if instead you prefer to increase the sensitivity towards a given type of gas, follow the instructions below: GASES LIGHTER THAN AIR, which therefore go upwards: - CARBON OXIDE AND MONOXIDE (actually these gases rise also due to the heat produced by their source) - ETHERS GASES HEAVIER THAN AIR, which therefore go downwards: - LPG So if you prefer greater sensitivity for a LPG GAS leak, it is advisable to position the sensor no further than 30/40 cm from the floor. If, on the other hand you prefer greater sensitivity for a saturation of Carbon Oxides, the sensor should be positioned between 1.30 m. and 1.50 meters from the floor.

It is obviously possible to place more sensors in the environment. TECHNICAL SPECIFICATIONS Power supply 10/16V dc.
