GDS-DEFENDER Flammable / Toxic / Oxygen / Refrigerant Gas Alarm Description
The GDS Defender gas leak detection system features remote sensors connected to the main control unit via a 3 core cable network. The control unit is an advanced design using the latest technology and provides a high integrity system whilst offering a significant cost saving over conventional gas alarm systems.

Standard sensors for use in commercial and light industrial applications, such as laboratories, workshops, boiler plant rooms, etc, are available for monitoring toxic, flammable, oxygen or refrigerant gases. Each gas sensor continuously monitors the atmosphere for any hazardous conditions. On detection of gas the sensor will indicate the gas level status A1, A2, A3 by LED indication and sounder. Information received by the control panel from the sensor is then displayed, indicating the zone, gas type and alarm status. Alarm levels that are exceeded are then able to activate user selectable relays and appropriate control actions.

Sensors may be used as stand alone devices when powered from a single sensor 24v DC supply (plug in jack) or the AC mains version sensors.
