MZX Infra-Red Flame detection offers unrivalled performance where hydrocarbon based fires exists. IR detection is less susceptible to radiation inhibitors than is UV, being able to detect through oil mist, smoke and vapour, all of which can be commonly associated with fires involving fuels. They are also less prone to false alarms from background radiation sources.

Infra red (IR) sensors are tuned to a bandwidth typical of the radiation emitted from carbon dioxide which is present in hydrocarbon fires. Single channel detectors are set to a fixed frequency and then rely on flame flicker, whereas triple channel detectors can monitor frequencies above and below the fire threshold filtering background radiation from non-fire sources. Array based IR detectors use 256 sensors making them sensitive yet extremely stable. The array can be configured to ignore hot spots such as exhausts, flues and flame stacks. The detector in addition to all other approvals is IEC61508, (SIL2) approved.

Some models can also incorporate a CCTV camera within the detector housing, providing real time images of the incident. All of the above detector types are available within the MZX range covering all categories of risks.
