Product variants

D7050 Multiplex smoke head

The symmetry of the D7050’s optical chamber allows 360° uniform smoke entry, but minimizes external light entry. Within the chamber, large smoke particles scatter infrared light which is detected by a gated, high-speed, photodiode sensor.

Commercial Type No.: D7050
Product No.: 4.998.140.391

 
D7050TH Multiplex detector head, fixed heat

The D7050TH has an optical smoke chamber and a 35°F (57°C) fixed-temperature sensor. Use it in confined areas where a fire increases air temperature slowly but substantially before the fire breaks confinement.

Commercial Type No.: D7050TH
Product No.: 4.998.140.394
