GAS DETECTORS AVUS-COMBI
TU 4215-007-07518266-2009

1.Purpose: Gas detector AVUS-Combi is designed for automatic continuous monitoring of the combustible gases concentration (methane and propane) and carbon monoxide in dwellings and public facilities in order to detect the excess of permissible concentrations and the timely adoption of effective measures to reduce gas contamination.
Designed in accordance with GOST R EN 50194-2008 and “Technical Regulation Draft on Safety Requirements to Gas Equipment in the Houses”.
"AVUS-COMBI" is a powerful home gas detector based on a modular design, provides the operating abilities of AVUS-M with additional functions:

2. Function:

- self-test function;

- uninterruptible power supply;

-alarm signal for excessive ambient temperature;

-wired and wireless interaction with the gas detectors and an external data system;
