APPLICATION

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, factories and shopping centres. The SGM595

is the gas sensor used with the complete range of Duomo detector

panels. All Duomo products are manufactured to meet relevant

European Normatives and proposals for explosive and toxic gases.

OPERATION

When the SGM595 senses the presence of gas it sends a 4 - 20mA

signal to the detector proportional to the level of gas. The detector

then operates a prealarm relay - used for remote sirens or visual

indicators if the level of gas continues to rise then the main alarm

relay is activated to break the electrical supply to a safety shut off

valve, and is fixed at 20% LEL of Natural Gas or LPG.

The SGM595 microprocessor conducts both self diagnostics and

automatically calibrates the sensor when ambient conditions vary,

thus avoiding false alarms.
