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.
