The Innovair DH100ACDCLWP is a photoelectric extended air
speed range duct smoke detector with a NEMA 4 Rated
watertight housing. This detector is specially designed for
use in either indoor or outdoor applications to provide a
degree of protection against falling dirt, rain, sleet, wind-
blown dust, splashing water and hose-directed water.
The DH100ACDCLWP is listed for an extended air speed
range of 100 to 4000 feet per minute (0.5 m/s to 20.2 m/s).
IMPORTANT NOTES
The following temperature limitations must be observed
during the installation and handling of this product:
Operating temperature: +32° to +131°F (0° to + 55°C)
Storage temperature:
–22° to +158°F (–30° to +70°C)
To maintain the watertight properties of this duct smoke
detector, watertight conduit and fittings must be used.
Mount the product with the conduit holes facing down-
wards, if possible.
Before Installing
Please thoroughly read the System Sensor Guide for Proper Use
of Smoke Detectors in Duct Applications, 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, Documents on Demand at
800/736-7672. NFPA Standards 72 and 90A should also be ref-
erenced for detailed information.
NOTICE: This manual shall be left with the owner/user of
this equipment.
IMPORTANT: This detector must be tested regularly follow-
ing NFPA 90 requirements. The detector should be cleaned at
least once a year.

[1] General Description
An HVAC system supplies conditioned air to virtually every
area of a building. Smoke introduced into this air duct sys-
tem will be distributed to the entire building. Smoke detec-
tors designed for use in air duct systems are used to sense the
presence of smoke in the duct.
Model DH100ACDCLWP Air Duct Smoke Detector is sup-
plied as a photoelectronic model. This smoke detection
method is combined with an efficient housing design that
samples air passing through a duct and allows 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.
The DH100ACDCLWP detector is designed to operate on 24
VDC/VAC, 120 VAC, or 240 VAC. Alarm and supervisory
relay contacts are available for control panel interface (alarm
initiation), HVAC control, and other auxiliary functions.
Auxiliary relays are also provided for fan shut down or sig-
naling of up to 9 other detectors in the loop for multiple fan
shut down. These detectors are not designed for 2-wire
applications.
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
occurs. Prior to cover installation, the green LED should be
flashing, indicating that the detector is powered and func-
tioning. To accurately determine detector status following
installation, System Sensor offers a variety of remote
annunciation and test accessories.
The DH100ACDCLWP can be reset by a momentary power
interruption, the reset button on the front cover, the control
panel, or remote reset accessory. The DH100ACDCLWP
incorporates a cover tamper feature that provides a trou-
ble signal after 7 minutes if the cover is removed or
improperly installed. Proper reinstallation of the cover
removes the trouble condition.
[2] Limitations Of Duct Smoke Detectors
The National Fire Protection Association has established that
DUCT DETECTORS MUST NOT BE USED AS A SUBSTITUTE
FOR OPEN AREA DETECTOR PROTECTION as a means of pro-
viding 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
DH100ACDCLWP 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.
