INSTALLATION AND MAINTENANCE INSTRUCTIONS
DH200RPL Intelligent Air Duct Smoke Detector
with Extended Air Speed Range
3825 Ohio Avenue, St. Charles, Illinois 60174
800/736-7672, FAX: 630-377-6495
Before installing detectors, please thoroughly read the NEMA 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 from
NEMA (National Electrical Manufacturers Association, 2101 L Street NW,
Washington, DC 20037). NFPA Standards 72 and 90A should also be ref-
erenced for detailed information.
The DH200RPL air duct smoke detector is 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.
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 DH200RPL has remote
test capability with the RTS451/RTS451KEY Remote Test Station.
IMPORTANT: This detector must be tested and maintained regularly fol-
lowing NFPA 72 requirements. The detector should be cleaned at least
once a year.
The DH200RPL incorporates a cover tamper feature. When the cover is
removed for more than 20 minutes, the unit loses communication at the
panel, a trouble is indicated at the panel and the alarm relay switches
states thereby shutting down fans, dampers and blowers. In the case
when the sensor is removed or when there is no power to the unit, only a
trouble is indicated at the panel (alarm relay does not work any longer).
General Description
An HVAC system supplies conditioned air to virtually every area of
a building. Smoke introduced into this air duct system is distrib-
uted to the entire building. Smoke detectors designed for use in air
duct systems are used to sense the presence of smoke in the duct.

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

[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 detec-
tor.
Install the sampling tube as follows:
3
1. Drill a ⁄4-inch (19mm) hole in the duct directly opposite the hole
Table 1. Sampling tubes recommended for different
duct widths:
already drilled 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 for moisture drainage.

*Must extend a minimum of 2⁄3 the duct width
3. From inside the duct, couple the other sections of the sampling tube
to the section already installed using the 1⁄2-inch conduit fittings sup-
plied. Make sure that the holes on both of the sampling tubes are lined
up and facing into the air flow.

(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.
ARROW
NOTE:
An alternate method to using the ST-10 is to use two ST-5 sam-
pling 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 plumb-
ing supply stores) may be used to fasten the sampling tube to
the other side of the duct. When using the flange/connector
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.

Different panel manufacturers offer different feature sets across their dif-
ferent panel models. As a result, certain features of the DH200RPL may be
available on some control panels, but not on others. The possible features
available in the DH200RPL, if supported by the control panel are:
hole where the flange will be used.
[5] Install The Filters
To install the sampling tube filters, simply push the filters into the sam-
pling and exhaust tube holes, as shown in Figure 6. If a metal sampling
tube is used, install the filters into the tube end.
1. Panel controls the LED operation on sensor. Operational modes are
RED blink, RED continuous, and off.
2. The remote output of the RA400Z does not follow the condition of the
duct smoke detector LED while in standby. When in alarm, the LED
output of the detector and remote will be identical.
CAUTION
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).
Please refer to the operation manual for the UL
listed control panel for specific operation of the DH200RPL.
Wiring Instructions
Disconnect power from the communication line before installing the
Figure 6. Sampling tube filter installation:
DH200RPL duct smoke detector.
Wire the DH200RPL duct smoke detector per the Control Panel Installation
Manual and Figures 9, 10 or 11.
Set the desired address on the sensor board address code wheel switches
(see Figure 7).
[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.
Figure 7. Rotary Address Switches
[7] Perform Detector Check
1. Perform STANDBY AND TROUBLE TEST per Section [9.2.1].
2. Perform MAGNET TEST per Section [9.2.2.1]. The
RTS451 test of Section [9.2.2.2] may substitute for this requirement.
3. Perform AIR FLOW TEST per Section [9.1].
For signal wiring, (the wiring between detectors or from detectors to auxil-
iary 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 flex-
ible 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.
4. Perform SMOKE RESPONSE TEST per Section [9.1.1].
[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.
Smoke detectors and alarm system control panels have specifications for
Signaling-Line Circuit (SLC) wiring. Consult the control panel manufactur-
er’s specifications for wiring requirements for the particular model control
panel being used before wiring the detector loop.
[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 person-
nel in verification of proper detector operation.
The DH200RPL 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.
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
[9.1.4] Air Flow Test using Dwyer Series 607 Differential Pressure
Transmitter
[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 han-
dler 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 section 9.1.2.
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 trans-
mitter 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 for proper operation.
[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 differ-
ential pressure between the sampling tubes, as described in 9.1.1.
Figure 8. Procedure for verifying air flow:
TO SAMPLING TUBE

Drill a ⁄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
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.
H0163-01
[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 suf-
fices 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.
