Data Sheet
Magnetic Test Feature
Test the detector's operation by placing the SMK-TM
Test Magnet next to the detector's LED for three
consecutive flashes. This causes the detector to send
an alarm.

Ordering information
D7050 Addressable Photoelectric Smoke Detector Head
The D7050 detects large smoke particles by scattering
light from a pulsed infrared source operating with a
gated, high-speed, photodiode infrared sensor. The
symmetry of the optical chamber allows 360° uniform
smoke entry, but minimizes external light entry.
Order number D7050
D7050TH Addressable Photoelectric Smoke and Heat
Detector Head
The D7050TH, in addition to an optical smoke
chamber, has an added 135°F (57°C) fixed-
temperature sensor that expands its application to
confined areas where a fire increases air temperature
slowly and where there is a substantial increase in air
temperature before the fire breaks confinement.
Order number D7050TH
