The CTS Defender gas leak detection system features remote sensors connected to the main control unit via a single 3 core cable. The control unit is of an advanced design using the latest technology and provides a high integrity system whilst enabling a significant cost saving over conventional gas alarm systems. Up to 64 sensors can be connected to this controller (with additional power supplies). Four zones are covered with 16 sensors/zone. This system is very different from other multi sensor systems. The alarm levels are pre-set with standard alarm limits. However, if non-standard alarm levels are required, request needs to be made when placing order.
Standard sensors for use in commercial and light industrial applications such as laboratories, workshops, boiler plant rooms etc are available for monitoring toxic, flammable or refrigerant gases.

The Status Indicator is a remote module lending itself to a wide variety of warning and alarm applications.
The module provides three user selectable levels of alarm, each having varying audible tones with ‘text selectable’
illuminated window indications. The sounder may be muted at any time with the flashing LED indicators going
constant but remaining lit until the alarm condition has cleared. Three relays are available for further repeater
or control actions, these relays may be selected to reset with the sounder or remain on with the indicators.

Our hazardous and safe area sensors for flammable, toxic/oxygen and refrigerant gasses
The CTS Data Link allows remote management of an on-site Combi Gas Detection System over a secure connection from any pc with internet access. A secure connection is created via the cloud to the Data Link module, which in turn is hard-wired to the Combi controller via a 4-core power/data cable to source the DC supply and the Combi MODBUS data.
