Read the System Sensor Guide for Proper Use of Smoke Detectors in Duct Appli-
cations (A05-1004), which provides detailed information on detector spacing,
placement, zoning, wiring, and special applications. Copies of this manual are
available online at www.systemsensor.com. Refer also to local standards and
codes of practice.
NOTICE: This manual shall be left with the owner/ u ser of this equipment.
IMPORTANT: This detector must be tested and maintained regularly. The de-
tector should be cleaned at least once a year.

DUCT DETECTORS MUST NOT BE USED AS A SUBSTITUTE FOR OPEN AREA
DETECTOR PROTECTION as a means of providing life safety. Nor are they a
substitute for early warning in a building's regular fire detection system.
This device will not operate without electrical power. Fire situations may
cause an interruption of power. The system safeguards should be discussed
with your local fire protection specialist.

This device will not sense smoke unless the ventilation system is operating
and the cover is installed.
For this detector to function properly, it MUST be installed according to the in-
structions in this manual. Furthermore, the detector MUST be operated within
ALL electrical and environmental specifications listed in this manual. Failure
to comply with these requirements may prevent the detector from activating
when smoke is present in the air duct.

[2] geneRaL DeScRiption

Smoke introduced into the air duct system will be distributed throughout the
entire building. Smoke detectors designed for use in air duct systems are used
to sense the presence of smoke in the duct.
Model D2E Duct Smoke Detector utilizes photoelectric technology for the de-
tection of smoke. This detection method, when combined with an efficient
housing design, samples air passing through the duct allowing detection of a
developing hazardous condition. When sufficient smoke is sensed, an alarm
signal is initiated and appropriate action can be taken to shut off fans,
blowers, change over air handling systems, etc. These actions can facilitate
the management of toxic smoke and fire gases throughout the areas served
by the duct system.

1. Sensor/power board assembly and covers
2. Three #10 sheet metal screws for mounting
3. One test magnet
4. Drilling template
5. One sampling tube end cap
6. One plastic exhaust tube
NOTE: A sampling tube must be ordered to complete the installation. It must
be the correct length for the width of the duct where it will be installed. See Ta-
ble 1 on page 3 to determine the inlet tube required for different duct widths.
