SensoMAG M40

SensoMAG M40 is a combined (optical-smoke and rate-of-rise) detector with digital processing algorithm, class A1/R. The integrated automatic drift compensation operation algorithm reduces significantly the false alarms.

SensoMAG M40 is suitable for installing in any conventional fire alarm system designed with fire alarm panel with fire alarm threshold between 10mA and 15mA.

SensoMAG M40 is a combined smoke and rate-of-rise temperature detector. It is the right choice for applications where the early detection of a fire situation is with great importance and high reliability is needed – in timbered, museums, hotel rooms.
