Four channel gas detection system
The AGDS-V is a four channel gas detection system designed for use in boiler houses, plant rooms and areas with a risk of gas escape or build up.
Auto isolate/close
In the event of a high alarm from one of the sensors, the AGDS-V will isolate/close any connected solenoid valve.
A low alarm indication is given on the control panel including ‘Mute’, ‘Reset’ and Emergency Stop buttons. Remote emergency stop buttons and thermal links can be monitored and there is also a fire alarm input which will close the gas valve when activated. There are two change over mains rated relays which can be used to activate a beacon/sounder, a fan or signal to a BMS system.
