– Early detection
– Immunity to parasitic phenomena
– Interactivity for hourly risk management

More information

This detector is a compendium of technology developed by our R&D department, it combines several sensors (2 optical and 1 thermal) and a powerful algorithm.

It enables to combine early detection and performance regardless of the nature of the combustion furnace.

This detector offers multiple (14) sensitisation possibilities for both smoke and temperature. Thanks to the interactivity with the panels, the sensitivity and detection mode can evolve according to a time slot for perfect temporal adaptation to the risks and constraints of the supervised area.

It has excellent immunity to parasitic phenomena such as water vapour, dust, etc., allowing it to be placed near a bathroom (limitation of installation cost and potential visual discomfort in the case of a hotel room, for example).
