AGDS-V Four Channel Gas Detection System with Valve Isolation
The AGDS-V is a four channel gas detection system designed for valve isolation in boiler houses, plant rooms and areas with a risk of gas escape or build up.

The AGDS-V is a gas detection system with gas valve isolation.
In the event of a high alarm from one of the detectors, the system will isolate the gas valve and operate any configured relays, beacons or sounders. Low alarm indication is also given. The OLED will display appropriate information about alarm situations and detector status..
Features
The OLED will display appropriate information about alarm situations and detector status.
Panel controls include ‘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.
Remote Indications
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.
Each relay is able to be set to report one of the below statuses:
- Generic Alarm
- Low Alarm
- High Alarm
- Detector Fault.
Product Features
- Gas detection (1-4 detectors)
- Multiple different gas types
- Clear OLED display
- Settable SELV relay (Low/High Alarm, Detector Alert, EM stop & Gas On conditions)
