Gas Alarm Systems is a division of ALVI Technologies, manufacturing alarms against gas leakage. The sensors can be portable, fixed or standalone. Places requiring small units with data logging capacities can opt for portable sensors, while places requiring more than four sensors with warning buzzers can opt for fixed ones.
Standalone sensors are also available having integrated external sensors. Audio visual alarms can either be integrated into the controller or can be mounted away from the controller for the sensors.
Gas alarms are available for sensing leakage of toxic and flammable gases like ammonia, carbon dioxide, carbon monoxide. Both portable and fixed types are used in buildings, wineries, hydro phonics, mines, cellars. They are available as either room or duct mounted with an integrated LCD.
To protect people from oxygen deficiency, portable and fixed type of oxygen deficiency indicators are available with 0 to 25ppm measuring range. Eleven types of refrigerant sensors are also included among the products in Gas Alarm Systems. The Refrigerant sensors confirm to AS1677.
An MSR Polyguard Cellar alarm is also a part of the product portfolio. This cellar alarm provides continuous monitoring of gas leakage in places like beverage dispensing units. Output is relayed in case of leaks which will activate the audio visual alarms, automatically shut off the gas supply and start the ventilating fans.
MSR Parkgard is a magnetic sensor for locating vacant spaces in parking areas. This sensor counts and displays the vacant spaces and also controls entry and exit barrier.
