Gas Alarm Systems has launched “VOC-Mixed Gas Alarm” which can be duct mounted or wall mounted. The gas alarm will continuously monitor for any VOC - mixed gases (volatile organic compounds, hydrocarbons, refrigerant leaks, toxic gases) and provide required A-V alarm or controls

A duct mount “VOC-Mixed Gas Alarm” can be either mounted on the fresh-air intake duct which will detect any incoming toxic fumes getting sucked through the ventilation intake and generate alarm for the building services team or close the fresh air ventilation intake

Similarly, any toxic spill or fume at any one section of the building can not spread into other section of the building if a duct mount VOC-Mixed gas sensor is installed in the return air duct.

Further, it will also provide “Early Fire Warning” by monitoring CO Products of Combustion.

Many building fires are smouldering fires due to burning of wood, carpet, upholstery and CO products of combustion is the perfect method for detecting this fire at a “Very Early Stage” – by the time smoke or flame is detected it is already too late.

Even aspiration type early smoke alarms do not provide early solutions.

This will also provide protection to buildings and occupants from terrorism gas threats.

The VOC-Mixed Gas Alarm comes in two models, either duct mount model or wall mount model. It has built in broad-spectrum VOC-Mixed gas sensor with life expectancy of more than 5 years (just replace the sensor after expiry of it is life).

There is an option of having a relay board which provide 2 x DPDT, 2 NO/NC relay contact, 5 A, 250 VAC for triggering A-V alarm or controlling ventilation flaps.

Further, it gives 4-20 mA analogue output for BMS or for any Gas Alarm Control System.

The wall mount is a stand alone self contained model with integral sensor, display, 4 x relays for alarms or triggering ventilation flap, 1 x fault relay (continuous watch dog), 3 x digital inputs for remote alarm re-set (say from security room), works on 24 V AC/DC (option 240 V AC operation) and has two 4-20 mA analogue output for BMS.

As an option, one can also have built-in A-V Alarm. The system comes with Alarm LED and system fault LED

Applications: The VOC-Mixed gas alarm will find wide applications for air-quality monitoring in commercial buildings, air-ports, enclosed railway station, hospitals, offices, laboratories, shopping centres, dangerous goods storage areas, warehouses, chiller plants, goods storage areas.

Above all, the gas alarm will also provide “Early Fire Warning” for smouldering products of combustion fires.
