The D7050 Photoelectric Smoke and Smoke Heat

Detector Heads are UL Listed, open-area photoelectric

smoke detectors designed for use with commercial fire

protective signaling systems and household fire

warning systems (see NFPA 72, the National Fire Alarm

Code). They are compatible with the FPD‑7024 or

D7024 Addressable Fire Alarm Control Panels

(FACPs), the DS7400Xi Control Panel, and the G

Series Control Panels.

They detect 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.

Use both of these smoke detectors for detection

circuits installed in areas where personnel are present.

The D7050TH has an added fixed-temperature sensor.

This expands the detector 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, such

as furnace rooms, closets, and other confined areas.

Functions

Detector Head and Base System

The D7050 Photoelectric Smoke and Smoke Heat

Detector 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 required for installation other than the hex key

used to tighten the tamper screw. Each detector head

requires a D7050-B6 detector base.

Chamber Check Self-diagnostics

The detector meets NFPA guidelines for sensitivity

testing, because you can visually inspect the detector

and check the flash rate of the LED. If the calibration

is out of factory-listed range, the LED on the detector

double flashes once every 3 sec to 8 sec. Follow the

instructions provided with the detector to clean it. The

detector also sends a dirty chamber report to the

control panel.

LED Operation

When the detector is operating normally, the LED

flashes once every 3 sec to 8 sec. In alarm, the

detector flashes at least once per second.
