designed for use in air duct systems are used to sense the
presence of smoke in the duct.
The DH200PL air duct smoke detector is a photoelectric
detector. This smoke detection method combines 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 at the fire control panel monitoring the detector,
and appropriate action can be taken to shut off fans, blowers and change over air handling systems, etc. This can
prevent the distribution or it can isolate toxic smoke and
fire gases throughout the areas served by the duct system.
NOTICE: This manual shall 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.
Two LEDs on each detector may illuminate, if programmed
by the system control panel, to provide a local alarm indication. There is also a remote alarm output for use with
auxiliary devices. The DH200PL has remote test capability
with the RTS451/RTS451KEY Remote Test Station.
General Description
An HVAC system supplies conditioned air to virtually every
area of a building. Smoke introduced into this air duct system is distributed to the entire building. Smoke detectors

Limitations of Duct 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
providing life safety. Nor are they a substitute for early
warning in a building’s regular fire detection system.
It is strongly recommended that the user read NFPA
Standards 90A, 72, and 101.
WARNING
NOTE: For ducts greater than 11⁄2 feet (0.46m) in width,
refer to sections [4], [4.1] and [4.2].
[3] Secure The Detector Housing To The Duct
Slide the foam gaskets over the tube bushings as shown
in Figure 3. Use the two 11⁄4″ long sheet metal screws to
screw the detector housing to the duct.
CAUTION: Do not overtighten the screws.
[4] Sampling Tube Installation for Ducts Greater
Than 11⁄2 Feet (0.46m) Wide
The sampling tube is identified by a series of air inlet holes
on the tube. A plastic tube is included for ducts up to 11⁄2
feet (0.46m) wide. All other lengths must be purchased
separately. Order the correct length, as specified in Table
1, for width of the duct where it will be installed. It is recommended that the sampling tube length extend at least
2
⁄3 across the duct width for optimal performance. The
exhaust tube is molded onto the base of the duct housing,
and the A2440-00 Exhaust Tube Extension is available as
an accessory in those cases where the molded exhaust port
does not extend at least 2 inches (50mm) into the duct.
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.
WARNING
This device will not sense smoke unless the ventilation
system is operating.
WARNING
In order to function properly, this detector must be installed
according to the instructions. Do not exceed the electrical or
ambient specifications or the detector will not function properly. This detector must be protected from the elements.

[1] Verify Duct Air Flow Direction And Velocity
The DH200PL duct smoke detector is designed to be used
in air handling systems having air velocities of 100 to
4000 feet per minute (0.5 to 20.32m/s). Be sure to check
engineering specifications to ensure that the air velocity in
the duct falls within these parameters. If necessary, use a
velocity meter to check the air velocity in the duct. See Air
Flow Test, section 9.1.
[2] Drill The Mounting Holes
Remove the paper backing from the mounting template
supplied. Affix the template to the duct at the desired
mounting location. Make sure the template lies flat and
smooth on the duct. Center punch holes A and B. Drill the
holes as indicated on the template.
D200-38-00
The sampling tube is always installed with the air inlet
holes facing into the air flow. To assist proper installation,
the tube’s mounting flange is marked with an arrow. Make
sure the sampling tube is mounted so that the arrow points
into the air flow (see Figure 4). Figure 5 shows the various
combinations of tube mounting configurations with respect
to air flow. Mounting the detector housing in a vertical orientation is acceptable, provided that a metal sampling tube
is installed and the air flows directly into the sampling tube
holes as indicated in Figure 4.

[4.1] Installation For Ducts Greater Than 11 ⁄ 2 Feet
(0.46m) But Less Than 8 Feet (2.4m) Wide
1. If the tube is longer than the width of the air duct, drill
a 3⁄4″ (19mm) hole in the duct opposite the hole already
cut for the sampling tube. Make sure the hole is 1″ to
2″ (25 to 50mm) below the inlet hole on the opposite
side of the duct to allow moisture drainage away from
the detector. If the tube is shorter than the width of the
air duct, install the end cap into the sampling tube as
shown in Figure 4. Sampling tubes over 3 ft. (0.91m)
long must be supported at the end opposite the duct
smoke detector.
2. Slide the tube into the housing bushing that meets the
air flow first. Position the tube so that the arrow points
into the air flow, as shown in Figure 4.
3. Secure the tube flange to the housing bushing with two
#6 self-tapping screws.
4. For tubes longer than the width of the air duct, the tube
should extend out of the opposite side of the duct. If there
are more than 2 holes in the section of the tube extending out of the duct, select a different length using Table
1. Otherwise, trim the end of the tube protruding through
the duct so that 1″ to 2″ (25 to 50mm) of the tube extend
outside the duct. Plug this end with the end cap and tape
closed any holes in the protruding section of the tube. Be
sure to seal the duct where the tube protrudes.

[4.2] Installation For Ducts More Than 8 Feet (2.4m) Wide
NOTE: To install sampling tubes in ducts more than 8 feet
(2.4m) wide, work must be performed inside the
air duct. Sampling of air in ducts wider than 8 feet
(2.4m) is accomplished by using the ST-10 sampling tube. If the tube is shorter than the width of
the air duct, install the end cap into the sampling
tube as shown in Figure 4 and support the end
opposite the duct smoke detector.

[6] Field Wiring Installation Guidelines
All wiring must be installed in compliance with the
National Electrical Code and the local codes having jurisdiction. Proper wire gauges should be used. The conductors used to connect smoke detectors to control panels and
accessory devices should be color-coded to prevent wiring
mistakes. Improper connections can prevent a system from
responding properly in the event of a fire.
3. From inside the duct, couple the other sections of the
sampling tube to the section already installed using the
1
⁄2-inch (12mm) conduit fittings supplied. Make sure
that the holes on both of the sampling tubes are lined
up and facing into the air flow.
4. Trim the end of the tube protruding through the duct so
that 1″ to 2″ (25 to 50mm) of the tube extend outside
the duct. Plug this end with the end plug and tape closed
any holes in the protruding section of the tube. Be sure
to seal the duct where the tube protrudes.
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 electrical tape to close off
some of the sampling holes so that there are a
total of 10 to 12 holes spaced as evenly as possible
across the width of the duct.
NOTE: Air currents inside the duct may cause excessive
vibration, especially when the longer sampling
tubes are used. In these cases a 3 inch (75mm)
floor flange (available at most plumbing supply
stores) may be used to fasten the sampling tube to
the other side of the duct. When using the flange/
connector mounting technique, drill a 1-inch to
11⁄4-inch (25 to 32mm) hole where the flange will
be used.
For signal wiring, (the wiring between detectors or from
detectors to auxiliary devices), it is usually recommended
that single conductor wire be no smaller than 18 gauge.
The duct smoke detector terminals accommodate wire
sizes up to 12 gauge. The last foot (0.3m) of conduit should
be flexible conduit (available in electrical supply houses),
which facilitates easier installation and puts less strain on
the conduit holes in the housing. Solid conduit connections
may be used if desired.
Smoke detectors and alarm system control panels have
specifications for Signaling-Line Circuit (SLC) wiring.
Consult the control panel manufacturer’s specifications for
wiring requirements for the particular model control panel
being used before wiring the detector loop.
The DH200PL detector is designed for ease of wiring. The
housing provides a terminal strip with clamping plates.
Wiring connections are made by stripping about 3⁄8-inch
(9mm) of insulation from the end of the wire, sliding the
bare end under the plate, and tightening the clamping plate
screw.
[5] Install The Filters
To install the sampling tube filters, simply push the filters
into the sampling and exhaust tube holes, as shown in
Figure 6. If a metal sampling tube is used, install the filters
into the tube end.
Two LEDs on each duct smoke detector may light, if programmed by the system control panel, to provide a local,
visible indication. Remote LED annunciator capability is
available as an option. Each duct smoke detector can only
be wired to one remote accessory.
Figure 6. Sampling tube filter installation:
Different panel manufacturers offer different feature sets
across their different panel models. As a result, certain
features of the DH200PL may be available on some control
panels, but not on others. The possible features available
in the DH200PL, if supported by the control panel are:
1. Panel controls the LED operation on sensor. Operational
modes are RED blink, RED continuous, and off.
2. The remote output of the RA400Z follows the condition
of the duct smoke detector LED.
Please refer to the operation manual for the UL listed
control panel for specific operation of the DH200PL.

Wiring Instructions
CAUTION
Disconnect power from the communication line before
installing the DH200PL duct smoke detector. Filters require periodic cleaning or replacement, depending on the amount of dust and dirt accumulated. Visually
inspect the filters at least quarterly; inspect them more
often if the dust accumulation warrants it. See Section
[9.1.2] for more information. Replacement filters can be
ordered (filter P/N F36-09-11).

[9.1.2] Air Flow Test using Aerosol Smoke
This test is intended for low-flow systems (100-500 FPM).
If the air speed is greater than 500 FPM, use a conventional
manometer to measure differential pressure between the
sampling tubes, as described in 9.1.1.
Figure 7. Rotary Address Switches
Drill a 1⁄4″ hole 3 feet upstream from the duct smoke detector. With the air handler on, measure the air velocity with
an anemometer. Air speed must be at least 100 FPM. Spray
aerosol smoke* into the duct through the 1⁄4″ hole for five
seconds. Wait two minutes for the duct smoke detector to
alarm. If the duct smoke detector alarms, air is flowing
through the detector. Remove the duct smoke detector cover
and blow out the residual aerosol smoke from the chamber
and reset the duct smoke detector. Use duct tape to seal the
aerosol smoke entry hole.

[9.1.3] Smoke Entry Test
[8] Install The Cover
Install the cover using the six screws that are captured in
the housing cover. Be certain filters are installed as specified in Section [5]. Make sure that the cover fits into the
base groove and that all gaskets are in their proper positions. Tighten the six screws.
To determine if smoke is capable of entering the sensing chamber, visually identify any obstructions. Plug the
exhaust and sampling tube holes to prevent ducted air from
carrying smoke away from the detector head, then blow
smoke such as cigarette, cotton wick, or punk directly at
the head to cause an alarm. REMEMBER TO REMOVE THE
PLUGS AFTER THIS TEST, OR THE DETECTOR WILL NOT
FUNCTION PROPERLY.
[9] Duct Smoke Detector Maintenance and Test
Procedures
Test and maintain duct smoke detectors as recommended
in NFPA 72. The tests contained in this manual were
devised to assist maintenance personnel in verification of
proper detector operation.
[9.1.4] Air Flow Test using Dwyer Series 607
Differential Pressure Transmitter
Verify the air speed of the duct using an anemometer. Air
speed must be at least 100 FPM. Wire the Dwyer transmitter as shown in Figure 8. Connect the leads of the meter
to either side of the 1000Ω resistor. Allow unit to warm up
for 15 seconds. With both HIGH and LOW pressure ports
open to ambient air, measure and record the voltage drop
across the 1000Ω resistor (measurement 1), 4.00 volts is
typical. Using flexible tubing and rubber stoppers, connect
the HIGH side of the transmitter to the sampling tube of
the duct smoke detector housing, and the LOW side of the
transmitter to the exhaust tube of the duct smoke detector housing. Measure and record the voltage drop across
the 1000Ω resistor (measurement 2). Subtract the voltage
recorded in measurement 1 from the voltage recorded in
measurement 2. If the difference is greater than 0.15 volts,
there is enough air flow through the duct smoke detector
Before conducting these tests, notify the proper authorities
that the smoke detection system will be temporarily out of
service. Disable the device or system under test to prevent
unwanted alarms.
[9.1] Smoke Entry Tests
[9.1.1] Air Flow
This product is designed to operate over an extended
air speed range of 100 to 4000 FPM. To verify sufficient
sampling of ducted air, turn the air handler on and use a
manometer to measure the differential pressure between
the two sampling tubes. The differential pressure should
measure at least 0.0015 inches of water and no more than
1.2 inches of water. Because most commercially available
manometers cannot accurately measure very low pressure
differentials, applications with less than 500 FPM of duct
air speed may require one of the following: 1) the use of
a current-sourcing pressure transmitter (Dwyer Series 607)
per Section 9.1.4 or; 2) the use of aerosol smoke per sec-

[9.1.5] Filter Replacement
The filters do not substantially affect smoke performance
even when up to 90% of the filter is clogged. Quarterly
visual inspection usually suffices to determine whether the
filters should be replaced because only a high percentage
of contamination affects performance. If further testing is
required, compare differential pressure readings with and
without the filters installed. If the difference exceeds 10%
replace the filters. In no case should the pressure differential fall below 0.0015 inches of water.
