The Tyco MR301Ex 516.021.003 is an intrinsically safe (I.S.) optical smoke detector, which is capable of detecting visible smoke that is produced by materials which smoulder or burn slowly.
The Tyco MR301Ex is suitable for general applications and areas where cable overheating may occur, such as electical service areas. The asymmetrical sampling chamber and signal processing techniques stop unwanted alarms caused by very small insects.
