The Innovair DH100LP model is a photoelectric detector ap-
proved for an extended air speed range of 100 to 4000 feet
per minute (0.5 m/s to 20.3 m/s) and has an operational
temperature range of 32°F to 131°F (0°C to 55°C).
Before Installing
Please thoroughly read the System Sensor Guide for Proper
Use of Smoke Detectors in Duct Applications (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 or via System Sensor’s toll free fax-back service, Docu-
ments on Demand at 800/736-7672. NFPA Standards 72 and
90A should also be referenced for detailed information.
NOTICE: This manual shall be left with the owner/user of
this equipment.
NOTICE: Model DH100LP is a direct replacement for Hon-
eywell model 32002812-006
IMPORTANT: This detector must be tested and maintained
regularly following NFPA 72 requirements. The detector
should be cleaned at least once a year.

[1] General Description
An HVAC system supplies conditioned air to virtually ev-
ery area of a building. Smoke introduced into this 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 DH100LP Air Duct Smoke Detectors utilizes pho-
toelectric technology for the detection of smoke. This de-
tection method when combined with an efficient housing
design samples air passing through the duct and allows
detection of a developing hazardous condition. When suf-
ficient smoke is sensed, an alarm signal is initiated at the
fire control panel monitoring the detector, 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.
DH100LP detectors are designed to operate with 12/24VDC
UL listed compatible 2-wire control panels. Alarm current
must be limited to 130mA or less by the control panel. Aux-
iliary relay contacts for control purposes are not available
for use with the DH100LP. Control must initiate from the
control panel.
For testing, the alarm can be enabled by a magnet activated
test switch or by the optional remote test station. The duct
smoke detector latches into alarm state when an alarm oc-
curs. A green LED flashes to indicate power, a red LED sig-
nals local alarm indication, and optional accessories offer a
variety of annunciation capabilities.
The DH100LP can be reset by a momentary power interrup-
tion, the reset button on the front cover, the control panel,
or remote reset accessory.
[2] Limitations Of Duct Smoke Detectors
WARNING
The National Fire Protection Association has established
that DUCT DETECTORS MUST NOT BE USED AS A SUB-
STITUTE 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.
System Sensor supports this position and strongly recommends
that the user read NFPA Standards 90A, 72, and 101. The
DH100LP Air Duct Smoke Detectors are listed per UL 268A.
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 sys-
tem is operating and the cover is installed.
For this detector to function properly, it MUST be installed
according to the instructions in this manual. Furthermore,
the detector MUST be protected from the elements and op-
erated within ALL electrical and environmental specifica-
tions listed in this manual. Failure to comply with these
requirements may prevent the detector from activating
when smoke is present in the air duct.
