Data Sheet

Tamper Detection
If the covers to the transmitter or receiver are
removed, the detector sends a trouble signal to the
control panel.
Trouble Detection
The receiver measures the intensity of the pulsed
infrared beam emitted by the transmitter over a period
of time and compares this data with a preset trouble
threshold. When 90% or more of the signal is lost for
more than 20 seconds, as might happen if an object
blocked the beam, the receiver sends a trouble signal
to the control panel.

Installation/configuration notes
Mounting Considerations
The transmitter and receiver mount on standard
3.5‑inch or 4‑inch square or octagonal back boxes or
European Beza boxes. The indicator plate mounts on a
standard single-gang back box.
The distance between the transmitter and receiver can
range from 30 ft (9 m) to 350 ft (107 m). When using
18 AWG (ISO 0.75 mm
2
) wire within conduit, the
indicator plate must be within 500 ft (152 m) of the
receiver.
Mount the detectors directly to the ceiling or to side
walls. Do not mount the units so that the beam runs
closer than 4 in. (10.2 cm) to the intersection of the
wall and the ceiling. Otherwise, place and space the
detectors according to NFPA 72.
Notice
The beam path should be clear of moving objects.
Avoid areas subject to normal smoke
concentrations such as kitchens and garages. Do
not install units where normal ambient
temperatures are below -22°F (-30°C) or above
+130°F (+54°C).
Lateral Spacing Between Systems
For adequate coverage, the lateral spacing between
adjacent detector systems must not exceed 60 ft
(18 m).
Wiring
System wire terminals accept 18 AWG to 12 AWG (ISO
0.75 mm
2
to 4 mm
2
) solid wires.

Ordering information
D296 24 V Projected Beam Smoke Detector
The D296 (24 V) provides an effective and unobtrusive
means of supervising public areas for fire protection. It
consists of a transmitter and a receiver that typically
mount on the ceiling or high on walls or columns and a
remote annunciation plate that mounts at eye level.
