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.
NOTICE: This manual shall be left with the owner/user of this equip-
ment.
IMPORTANT: This detector must be tested and maintained regularly fol-
lowing NFPA 72 requirements. The detector should be cleaned at least
once a year.
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 designed for use in air duct systems are
used to sense the presence of smoke in the duct.
The ADP-R 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
Contents of the Duct Smoke Detector Housing Kit
The ADP-R Duct Smoke Detector consists of the following items
(See Figure 1.):
Figure 1: Exploded View Of Duct Smoke Detector Components
NOTE: For ducts over 1
1⁄2 feet, longer sampling tubes must be ordered to complete the installation. They must be the correct length for the width of
the duct where they will be installed. See Table 1 on page 3 to determine the sampling tube required for different duct widths.

sensor
2. Two #10 x 1
1/4″ sheet metal mounting screws
3. Two sampling tube filters
4. One test magnet
5. Drilling template
6. Two foam gaskets
7. Four #6-self tapping mounting screws for the
sampling tube and optional exhaust tube exten
sion
8. One sampling tube end cap
9. One plastic sampling tube
10. One #8 self-tapping screw for plastic sampling

Contents Of The Duct Smoke Detector
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.
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 ADP-R has remote test
capability with the RTS451/RTS451KEY Remote Test Station. The ADP-R
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).
WARNING
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.

[1] Verify Duct Air Flow Direction And Velocity
The ADP-R duct smoke detector is designed to be used in air handling
systems having air velocities of 100 to 4000 feet per minute. 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.
[2.1] Sampling Tube Installation for Ducts Less Than 11⁄2 Feet
Wide (see Figure 2)
1. Remove the front cover.
2. Slide the plastic sampling tube into the housing bushing.
3. Align the holes in the bushing with the holes in the sampling tube. Make
sure there are 6 exposed holes on the plastic sampling tube. Secure with
the #8 self-tapping screw into the bottom of the permanent tube (shown
in Fig. 2).
NOTE: The sampling tube end cap is critical to the proper operation of
the duct smoke detectors. The end cap is needed to create the
proper air flow to the sensor of the duct smoke detector.
NOTE: For ducts greater than 1
1⁄2 feet 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 #10 x 1
1⁄4″ 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
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 1
1⁄2 feet 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 into the duct.
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 But Less Than 8
Feet Wide
1. If the tube is longer than the width of the air duct, drill a 3⁄4″ hole in
the duct opposite the hole already cut for the sampling tube. Make
sure the hole is 1″ to 2″ 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. 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

[4.2] Installation For Ducts More Than 8 Feet Wide
NOTE: To install sampling 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 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.
Install the sampling tube as follows:
1. Drill a 3⁄4-inch hole in the duct directly opposite the hole already drilled
for the sampling tube. Make sure the hole is 1″ to 2″ below the inlet
hole on the opposite side of the duct to allow for moisture drainage.
2. Slide the sampling tube with the flange into the housing bushing that
meets the air flow first. Position the tube so that the arrow points into
the air flow. Secure the tube flange to the housing bushing with two
#6 self-tapping screws.
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.
4. Trim the end of the tube protruding through the duct so that 1″ to 2″ 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.
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 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 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 over the tube end.

bottom of the detector housing (Figure 14).
2. Verify system control panel alarm status and control panel execution
of all intended auxiliary functions (i.e. fan shutdown, damper control,
etc.)
3. The detector is self-restoring when the magnet is removed. Verify that
the system control panel has reset; panel may have to be reset.

[9.2.2.2] RTS451/RTS451KEY Remote Station Test
The RTS451/RTS451KEY Remote Test Station facilitates test of the alarm
capability of the duct smoke detector. These accessories provide the
stimulus to initiate an alarm condition at the detector. The detector is
self-restoring when the accessory test stimulus is removed. Verify that the
system control panel has reset; panel may need to be reset.
[9.2.3] Sensitivity Tests
Notify the proper authorities that the smoke detector system is undergo-
ing maintenance, and that the system will temporarily be out of service.
Disable the device or system undergoing maintenance to prevent unwant-
ed alarms and possible dispatch of the fire department.
[9.3] Maintenance of Duct Smoke Detectors
[9.3.1] Air Filters
1. Turn off power to the system.
2. Remove and inspect sampling tube filters.
3. If filters are heavily coated with dirt, replace them with new filters
(p/n F36-09-11). If they are not heavily coated, use a vacuum cleaner
or compressed air nozzle to remove dust, then reinstall the filters.

H0136-00
H0133-00

[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.
[9.2] Standby, Alarm, And Sensitivity Tests
[9.2.1] Standby And Trouble
Standby — If the system control panel is programmed, look for the
presence of the flashing LEDs through the transpar-
ent housing cover. The LED will flash with each communi
cation.
Trouble — If the detector LEDs do not flash, then the de-tector lacks
power (check wiring, panel pro-gramming, or power sup
ply), the detector board is missing (replace), or the unit
is defective (return for repair). Additionally, if the cover
is removed for more than 20 minutes, the LEDs of the
detector will not flash.
Test — The trouble condition can be caused intentionally to
verify correct operation of the system. Remove the detec
tor board to cause a trouble condition locally and at the
system control panel.
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).
[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.
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 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 manufactur-
er’s specifications for wiring requirements for the particular model control
panel being used before wiring the detector loop.
The ADP-R 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 of insulation from the end of the wire, sliding
the bare end under the plate, and tightening the clamping plate screw.
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 ADP-R may be
available on some control panels, but not on others. The possible features
The possible features available in the ADP-R, 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 does not follow the condition of the
duct smoke detector LED in standby, but follows the LED condition of
the duct smoke detector in alarm.
Please refer to the operation manual for the UL listed control panel
for specific operation of the ADP-R.

[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.
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 flow-
ing 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.
*Aerosol smoke can be purchased from Home Safeguard Industries,
Malibu, CA. Phone: [phone].
[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.
[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 measure-
ment 2. If the difference is greater than 0.15 volts, there is enough air flow
through the duct smoke detector for proper operation.
[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].
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.
[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.
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 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.
