The TOC-10 Series of Flammable Gas Detectors from Sensors Ltd are state of the art for gas detection in residential buildings, commercial kitchens, Schools and general building services.

The unit is supplied pre-calibrated for the target gas, this is the option for LPG (Propane), standard options are also available for Natural Gas (Methane) or Town Gas.

For basic operation only mains power is required (a pre wired model with 5M long mains lead) is available. For more advanced operation there are two relay outputs.

Relay one activates at the first alarm level, relay two at the second alarm level.

The relays can be used to interface to other devices such as remote indicators, gas shut off valves, autodiallers etc.

The built in sounder provides clear, and very loud indication of a gas alert and indicators on the front of the unit show which level of alarm has been activated.

This unit utilises industry standard pellistor gas sensor technology NOT cheap semi-conductors. The detector therefore has accurate and stable calibration and a long operating life.

The gas detector is in standard 2 gang format, this means it can be either surface mounted using the 2 gang patress supplied or flush mounted using standard 2 gang plaster boxes.
