The Duomo GS100M is a wall or panel mounted microprocessor based gas detector control. It can be configured to meet customer requirements. The following parameters can be changed using on board dip switches: Sensor on /off. Type of Gas to be sensed: Selectable - Explosive or toxic. Main Alarm delay period: Selectable - 3 or 20 seconds. Main Alarm relay action: Selectable - latching or auto reset.
The GS100M has two plug in terminal blocks. One is for the incoming mains supply and alarm circuit wiring and the second is for connecting the sensor wiring. This reduces the chance of incorrect site wiring. The printed circuit board has an overload light which indicates when a short circuit or an overload has occurred on the sensor wiring.

Duomo is recognised within the Gas industry for providing a comprehensive range of low cost, high reliability gas detection for many applications. We have installed and commissioned Natural gas and carbon monoxide sensors in applications such as boiler rooms, kitchens, car parks, aircraft hangars, factories and shopping centres. The GS100M is the command center for the complete range of Duomo Gas Sensors. All Duomo products are manufactured to meet relevant EuropeanNormatives and proposals for explosive and toxic gases.
When the remote sensor detect the presence of the Target Gas a 4-20mA signal is sent to the detector, proportional to the level of gas. The GS100M then operates a pre-alarm relay - used for remote sirens or visual indicators if the level of gas continues to rise then the second pre alarm is actuated. In the case of explosive gases, when the level of gas reaches 20%LEL, the main alarm relay is activated to break the electrical supply to the Gas Safety Shut Off Valve. The GS100M also has a seperate volt free sensor fault relay. This actuates if the correct return signal is not sensed by the Detector.The GS100M can be configured to detectexplosive and/or toxic gases.
