General Description
Please thoroughly read the System Sensor Manual I56-
473-XX, 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 at no
charge from System Sensor. NFPA Standards 72 and 90A
should also be referenced for detailed information.
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.
The DH500ACDC Air Duct Detector Housings are used with
System Sensor’s Model 1551 ionization detector heads and
Model 2551 photoelectronic detector heads (purchased sep-
arately). These two smoke detection methods are combined
with an efficient housing design that samples air passing
through a duct and allows detection of a developing hazard-
ous condition. When sufficient 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 and blowers, change over air handling systems, etc.
This can prevent the distribution of toxic smoke and fire
gases throughout the areas served by the duct system.
NOTICE: This manual should be left with the owner/user
of this equipment.
IMPORTANT: This detector must be tested and maintained
regularly following NFPA 72 requirements. The detector
should be cleaned at least once a year.

A. Installation for Ducts Less Than 8 Feet Wide
1. If the inlet tube is longer than the width of the air duct, Install the inlet tube as follows:
drill a 3/4-inch hole in the duct directly opposite the
hole already cut for the inlet tube.
If the inlet tube is shorter than the width of the air duct,

of the duct housing. Position the tube so that the arrows
point into the air flow. Secure the tube flange to the
housing bushing with the two #6 self-tapping screws.
3. From inside the duct, couple the other section of the
inlet tube to the section already installed using the 1/2-
inch conduit fitting supplied. Make sure that the holes
on both of the air inlet tubes are lined up facing the
direction of air flow.
2. Slide the inlet tube into the bushing located in the center
of the duct housing. Position the tube so that the arrows
point into the air flow.
3. Secure the tube flange to the housing bushing with the
two #6 self-tapping screws.
4. For tubes longer than the width of the air duct, the tube
should extend through the opposite side of the duct. If
there are more than 2 holes in the section of the tube 4. Trim the end of the tube protruding through the duct so
extending from the duct, select a different tube length
using Table 1. Otherwise, trim the end of the tube pro-
truding through the duct so that 1 to 2 inches of the tube
extends outside the duct. Plug this end with the tube
end plug and tape closed any holes in the protruding
section of the tube. Be sure to seal the duct when the
tube protrudes.
that 1 to 2 inches of the tube extends outside the duct.
Plug this end with the tube end plug and tape closed any
holes in the protruding section of the tube. Be sure to
seal the duct when the tube protrudes.
5. Any tube (over 3 feet long) that doesn’t protrude through
the duct (on the side opposite the housing) must be sup-
ported by other means.
5. Any inlet tube over 3 feet long must be supported on the
opposite side of the duct detector housing.
NOTE: An alternate method to using the ST-10 is to use
two ST-5 inlet tubes. Remove the flange from one
of the tubes and install as described above. After
the installation, use electrician’s tape to close off
some of the sampling holes so that there are a total
of 12 holes spaced as evenly as possible across the
width of the duct.
WARNING
In no case should more than 2 air inlet holes be cut off the
tube. There must be a minimum of 10 holes in the tube
exposed to the air stream.
B. Installation for Ducts More Than 8 Feet Wide
NOTE: To install inlet tubes in ducts more than 8 feet
wide, work must be performed inside the air duct.
Sampling of air in ducts wider than 8 feet is accom-
plished by using the ST-10 inlet sampling tube.
NOTE: Air currents inside the duct may cause excessive
vibration. This vibration can slowly open the
seal around the tube and permit air to escape. To
prevent this from occurring, a 3-inch floor flange,

There may be situations where duct widths are not as
specified for the installation. In such cases, it is permissible
to modify an inlet sampling tube that is longer than neces-
sary to span the duct width.

Recommended Detector Maintenance Procedure
NOTE: Notify the proper authorities that the smoke detec-
tor system is undergoing maintenance and will be
temporarily out of service. Disable the zone or sys-
tem undergoing maintenance to prevent unwanted
alarms and possible dispatch of the fire depart-
ment.
Periodic Maintenance Requirements
Air duct smoke detectors should be maintained at least
once a year – more often if the detector heads become
obviously dirty. The detectors must also be cleaned imme-
diately after a fire. Failure to properly maintain air duct
smoke detectors may cause unnecessary false alarms.

CAUTION
Models 1551 and 2551 can be used with the DH500ACDC if
the following constraints are observed.
1. There may be a limit to the number of devices per zone
that can have their LEDs latched on. The number of
devices is determined by the control panel and its abil-
ity to supply LED current. If more than the maximum
number of devices is on the same loop, do NOT use
the DH500ACDC for control purposes. Control for duct
applications would need to come directly from the con-
trol panel or by using control modules.
