The Bosch D7050 MUX smoke head and Bosch D7050TH MUX smoke head w/ fixed heat (135°F) are UL Listed, open‑area photoelectric detectors. Also, they come designed for use with commercial fire protective signaling systems and household fire warning systems. The symmetry of the optical chambers allows 360° uniform smoke entry but minimizes external light entry. In the chamber, large smoke particles scatter infrared light from a pulsed source operating with a gated, high‑speed, photodiode sensor.
The Bosch D7050TH has an added fixed‑temperature sensor. Use in confined areas, such as furnace rooms and closets. Areas where a fire increases air temperature slowly but substantially before the fire breaks
confinement.
Furthermore, the smoke and smoke/heat heads are part of a compound system of detector head and base. The detector base installs over a back box and contains all the wiring. The detector head attaches to the base by aligning the head with the base and turning it clockwise. No tools are require for installation other than the hex key used to tighten the tamper screw. Each detector head requires a D7050-B6 detector base.
