Setting the Duct Sensor’s Address
Addressable Duct Sensors
4098-9755 or 4098-9756
(MAPNET II/IDNet)
The procedures that follow are used to install the 4098-9755 or 4098-9756
addressable duct sensors. See Figure 1 for the location of the duct sensor DIP
switches. The instructions provided show how to set the address at each sensor
and also how to make electrical connections. Addressable smoke duct sensors are
connected to a 2120 Multiplex Communicating Device Transponder (CDT), 4010
Fire Alarm Panel, 4020 Fire Alarm Panel, 4100+ Fire Alarm Panel, or 4120 Fire
Alarm Panel by a single twisted-shielded wire pair (MAPNET II/IDNet).
General
Address Setting for the 2120
CDT System (use with
4098-9755 only)
Duct sensor addressing is critical since the 2120 Communicating Device
Transponder (CDT), 4010, 4020, 4100+, and 4120 Systems report alarms and
troubles per duct sensor rather than per zone. Each duct sensor has a unique
address. This address is associated with a custom label which identifies its
physical location within a building. The duct sensor’s address and location must
match up with the address listed in the specification sheets of the 2120 Job
Configuration Report or P rogrammer’s Report for the 4010, 4020, 4100+, or
4120 System. You should have the appropriate specification sheets with you
during this part of the installation.
1. Using the 2120 Job Configuration Report, find the entry for the duct sensor
you are about to install. The CUSTOM LABEL column provides the
location while the DEVICE ADDRESS column provides the switch setting
data.
2. Using the switch setting data for the duct sensor you are installing set the
duct sensor’s address using Figure 3. Loose n t he four screws securing the
clear plastic cover to the housing base. Locate the DIP switch on the duct
sensor’s PCB assembly in the wiring compartment (see Figure 1). Use a
small screwdriver or pen to set the switches.
For the switch setting data in the DEVICE ADDRESS column, “1” is switch
ON while “0” is switch OFF.
3. Recheck the location of the sensor and its address before electrical
installation. Mark an address label with the appropriate address for your
duct sensor by shading a label box for each sensor DIP switch in the ON
position. Then apply the label to the sensor near the sensor’s DIP switches.
4. Secure the duct sensor’s clear plastic cover to the housing using the four
screws (Torque screw to 8-10 inch-pounds).
Address Setting for the 4010,
4020, 4100+, or 4120
1. Using the System Point Summary for the 4010, 4020, 4100+, or 4120, find
the entry for the duct sensor you are about to install. The ZONE NAME
(with a “M” prefix) and CUSTOM LABEL are located in the SYSTEM
POINT SUMMARY.
For example, Address M1-7 (for the 4010, 4100+, or 4120 System) is
shaded in Figure 2. M1 is the addressable channel while -7 is the device
address on the channel. For a duct sensor with Address M1-7, address 7
must be set on the duct sensor’s DIP switches. Address 7 is illustrated in
Figure 3.

Addressable Duct Sensors
Addressable Duct Sensor
Compatibility
Addressable duct sensors are connected to a 2120 CDT (4098-9755 only), 4010, 4020,
4100+, or 4120 Fire Alarm System by twisted pair-wire (MAPNET II/IDNet). The
duct sensor obtains both power and data over this wire pair. (Shielded twisted pairwire for the MAPNET II/IDNet circuit is recommended; if not shielded or twisted,
consult Simplex Sales Engineering.) For relay operation (4098-9756 only), a separate
24VDC source of power is required in addition to the MAPNET II/IDNet lines. Refer
to Table 1 for duct sensor compatibility.
Note: The 24VDC power source must originate from a fused power supply listed for
fire protection signaling use, or from the Fire Alarm Control Panel (FACP)
power supply.

Installation
Pre-Installation Routines
The 4098-9685, 4098-9686, 4098-9688, 4098-9755 or 4098-9756 Duct
Detector/Sensor should be installed in a location of relatively nonturbulent air
flow and within the intended operating velocity range of 300-4000 feet-perminute (91 to 1220 M/min.).
Simplex recommends measurements of air flow and examination of engineering
specifications that define expected duct air velocities under all conditions. This
is done to determine if a location is suitable for duct detector/sensor operation.
An Alnor Instrument Co. (Chicago) Model 6000P Velometer or equivalent (not
supplied) may be used to check the duct air velocity.
Rules to Follow
1. It is recommended to locate detectors/sensors a minimum of six duct widths
downstream from bends or inlets. Such locations ensure that air flow is nonturbulent and that smoke is properly mixed with air in the duct for maximum
detector/sensor efficiency. See Figures 9 and 10.
Note: Installation of a duct detector/sensor to a round duct is the same as
shown in Figures 9 and 10 as long as the round duct is 18 inches or
larger (45.7 cm) in diameter.

Figure 10. Duct Housing Placement - Location of Air Return Inlet
2. Locate duct housings so that dampers do not restrict air flow at the
detector/sensor location. See Figure 11.
3. Locate air duct detectors/sensors on the return or supply duct of the
equipment’s air handling system. However, detectors/sensors should NOT
be installed in the return air damper branch. See Figure 11.

4. Locate air duct detectors/sensors on branch lines if close identification of
the alarm source is required.
5. Locate air duct detectors/sensors on the downstream side of filters to sense fire
in filters. However, should the filters block, sufficient air flow may not be
available for proper air duct detector/sensor operation. See Figure 11.

6. Whenever possible, locate air duct detectors/sensors where they can be
conveniently observed and readily serviced.
7. Locate the air duct detectors/sensors in return air ducts ahead of mixing
areas.
8. Do not locate air duct detectors/sensors next to outside air inlets unless you
want to monitor smoke entry to the handling system from an adjacent area.
9. Locate air duct detectors/sensors upstream of air humidifiers and cooling
coils.
Duct Detector/Sensor
Installation
1. Tape the template (Figure 18) on the duct surface as shown in Figure 12.
Note: Do not position the Template with edges angled with respect to air flow
direction (Figure 12) .
2. Drill two 1 1/4 inch (31.75 mm) holes (marked “A” in Figure 18) as located
by the template. Remove template after holes have been drilled.
3. If the duct is more than 3 feet (0.9 m) wide, then punch a 1-inch (25.4 mm)
hole in the duct wall directly opposite the upstream 1 1/4 inch (31.75 mm)
hole. See Figure 13. This hole is used to support the inlet tube.

secure the duct housing (no pre-drilling is required). Torque screws 10-12
inch-pounds.
Inlet Tube Installation (See Figures 13 and 14)
7. Install the inlet tube by inserting the rubber plug end of the tube into the
upstream tube receptor located in the rear of the duct housing. The inlet
tube must be installed through the hole i n t he housing corner next to the
smoke port/air flow test holes. Place the tube retainer (supplied) over the
inlet tube so that the tab on the tube retainer goes into the slot on the inlet
tube. Make sure the tube retainer is in the proper orientation so that the
holes in the inlet tube face upstream into the airflow. The tab on the inlet
tube retainer bracket indicates the inlet hole side of the pipe.
Note: If a support hole is being used, be sure to insert the inlet tube through
the hole on the far side of the duct.
8. Fasten the tube retainer using two #8 machine screws.
Notes:
1. Be sure to securely tighten the #8 machine screws to prevent accidental
turning of the tube within the receptor. Torque screws 16-18 inch-pounds.
2. If the inlet protrudes thr ough the far side of the duct, seal t he opening around the
tube (on the outside of the duct) with duct sealant.
Exhaust Tube Installation (See Figures 13 and 14)
9. Install the exhaust tube into the downstream receptor of the duct housing
base. Place the inlet tube retainer bracket (supplied) over the exhaust tube
so that the tab on the tube retainer goes into the slot on the exhaust tube.

Detector/Sensor Replacement
To properly remove and replace the detector/sensor to the base (see Figure 1):
1. Remove power from the Duct Detector/Sensor.
2. Loosen the four screws that secure the clear plastic cover to the housing base.
3. Insert a small blade screwdriver into the lock release slot in the base. Rotate
the detector/sensor counterclockwise to remove it from the base.
4. Remove dust cover from the replacement detector/sensor.
5. Insert the detector/sensor into the base and rotate until fully seated, continue
rotation until lock has been engaged.
6. Secure the clear plastic cover to the housing using the four screws (Torque
screws to 8-10 inch-pounds).
Note: An audible “snap” indicates proper contact engagement.
WARNING: System will not operate with dust cover in place.
DC Operation Detector
Testing
Periodic Air Test
Basic Unit Test
With power applied to the Duct Detector, introduce aerosol using the 553-673 Smoke
Detector Aerosol Tester i nt o the Duct Detector through the test port holes (Figure 1).
Or, place the 553-810 Magnet Tester next to the test location on the clear Housing
Cover (Figure 16). Observe “ALARM” LED operation on the detector or the
“ALARM” LED on the interface PCB for DUCT Sensors. Restore normal operation
to detector by doing a system reset at the panel, or by momentarily removing power,
or by removing and replacing the detector head. Restore normal operation to sensor
by doing a system reset at the panel.
With the air handling unit turned on, and all filters and dampers in place, open one of
the test port holes (Figure 1) by removing one of the red covers marked “Test” on the
Duct Detector/Sensor. Measure the airspeed velocity inside the duct housing using
the Alnor Instrument Co. Air Velocity Meter (Model 8500) or equivalent (not
supplied).
Note: Refer to manufacturer instructions when performing this test.
Insert the probe in the test opening and measure the airspeed directly in front of the
sampling tube. Airspeed measured at this point should be 200 fpm or greater.
Airspeed measured at the inlet is typically 40% – 60% of the actual airspeed in the
duct housing. Any deviation from the recommended installation rules described
previously can cause this measurement to be unreliable.
If the airspeed measurement is less than 200 fpm, then a direct airspeed measurement
should be taken inside the duct. Airspeed inside the duct should be between 300 fpm
and 4000 fpm (91 to 1220m/min) for proper operation of the smoke detector/sensor.
Airspeed below 200 fpm measured inside of the duct detector/sensor may indicate a
sampling or exhaust tube obstructed by debris. Tubes should be inspected and
cleaned as required.
IMPORTANT: Make sure the test port covers are replaced after testing.

(574-709) for detailed information on Detectors and Sensors.
Sensor Magnet Test
The following test method is suitable for functional checks of sensor bases
during installation; however, testing with aerosol must be performed to comply
with NFPA requirements.
Position the 553-810 Magnet Tester on the cover side, below either of the arrow
marks (see Figure 16), not between the two arrow marks. Testing a sensor
with a magnet reports a value of 255 for actual / peak (exception 4010 panel).
Clear the peak value after testing.
Detector Magnet Test
The 4098-9601 photoelectric detector may be tested by placing a magnet at the
location indicated by a “TEST” mark embossed on the cover for four (4)
seconds (see Figure 16). Use the Simplex Magnet Tester (Part No. 553-810),
Table 4, and the following information to test detectors.

Magnetic Test for Detectors
and Sensors (continued)
Preferred Method of Testing
Smoke Detectors/Sensors
When placing the magnet near the location (see Figure 16) indicated by a
“TEST” mark embossed on the cover, the visible LED flashes indicating the
detector's condition. The following are descriptions of what you should see
when using the MAG TEST.
• NORMAL - When in MAG TEST, the detector latches into alarm if the
detector is within calibration range and the visible LED stays ON.
• MORE SENSITIVE - When in MAG TEST, if the detector is more
sensitive than the maximum calibration, the visible LED quickly flashes,
twice a second. Following the sixth flash, the detector latches into alarm
and the visible LED stays ON.
• LESS SENSITIVE - When in MAG TEST, if the detector is less sensitive
than the minimum calibration, the visible LED slowly flashes four times,
once every two seconds. Following the fourth flash, the detector latches
into alarm and the visible LED stays ON.
• NON-FUNCTIONAL - If the detector is less sensitive than the minimum
allowable sensitivity, the visible LED does not flash normally. When in
MAG TEST, the visible LED slowly flashes four times, once every two
seconds. After the fourth flash, the detector does NOT latch into alarm and
the LED stops flashing and turns OFF.
If the detector is out of the normal operating range, it should be cleaned. If the
detector still indicates as other than normal sensitivity, replace the detector.
NFPA requires annual testing of the det ectors/sensors a t their installed location
using smoke or aerosol. With the air handling unit turned on, open one of test
port holes (Figure 1) by removing the red cover on the duct detector/sensor
housing. Using an extended nozzle on the smoke detector aerosol tester
(553-673) spray a 4-second burst of aerosol through the test port but not dire ctly
at the detector/sensor head. The nozzle of the smoke detector aerosol tester
should not extend beyond the inlet tube (see Figure 17). Aerosol is sprayed into
the stream of incoming air and not directly into detector/sensor.
IMPORTANT: Make sure the test port covers are replaced after testing.

Testing
Basic Unit Test
With the air handling unit OFF and power applied to the air duct detector/sensor,
introduce aerosol into the detector/sensor or activate the built-in test feature as
described in the 4098 Detectors, Sensors, and Bases Application Manual 574-709.
Observe alarm LED operation. Restore normal operation to the detector by doing
a system reset at the pane l , or by momentarily removing power, or by removing
and replacing the detector head after aerosol has been cleared from its chamber.
Restore normal operation to the sensor by doing a system reset at the panel.
Basic Unit Test with 4098-9830 or 2098-9808 Option
Perform the basic unit test above and observe both alarm LED operation of the
detector/sensor and remote alarm indicator. Restore normal operation to the
detector by doing a system reset at the panel, or by momentarily removing power,
or by removing and replacing the detector head after aerosol has been cleared from
its chamber. Restore normal operation to the sensor by doing a system reset at the
panel.
Basic Unit Test with 4098-9834 or 2098-9806 Option
Perform the basic unit test above and observe both alarm LED operation of
detector/sensor and remote alarm indicator. Restore normal operation to detector by
doing a system reset at the panel, or b y momentari l y removing power, or by re movi ng
and replacing the detector head after aerosol has been cleared from its chamber.
Restore normal operation to the sensor by doing a system reset at the panel.
An alternate test method is to insert the key into the keyswitch and turn the key

Air Differential Pressure Test
Maintenance
With the air handling unit turned on and all filters and dampers in place, measure
the air differential pressure using a Dwyer Instrument Co. (Michigan City, Ind.)
No. 20026 0 to 2” H
Take measurements from inside of the detector/sensor housing before the cover is
installed. Measure the difference in pressure between the intake tube and the
exhaust tube. The pressure differential for all duct velocities between 300 and
4000 feet per minute (91 to 1220 M/min.) shall not be less than 0.015 inches (.381
mm) of water nor greater than 1.55 inches (39.370 mm) of water.
After testing is completed, secure the clear plastic cover to the housing using the four
screws (Torque screws to 8-10 inch-pounds).
The duct housing sampling tube holes should be checked periodically for
cleanliness, thus assuring easy air entry. Any dust or debris should be removed
from tube or tube holes.
The maintenance program of the particular detector/sensor used should be
carried out in accordance with the detector/sensor installation instructions.
Vacuuming the detector/sensor air entry areas should be performed annually, or
as required.
