PRODUCT OVERVIEW
PRODUCT APPLICATION
SL-2000 Series duct smoke detectors provide early detection of
smoke and products of combustion present in air moving through an
HVAC duct supply, return, or both in commercial, industrial, and
residential applications. These devices are designed to prevent the
recirculation of smoke in areas by the air handling system’s fans and
blowers. Complete systems may be shut down in the event of
smoke detection.
The duct smoke detector units are designed to operate in duct
widths from 6” to 10’ wide with an air velocity between 100 to 4,000
feet per minute. To verify correct installation, the pressure
differential between the sampling (high side) and exhaust (low side)
tubes should be measured using a Magnehelic pressure gauge or
equivalent. An acceptable reading is between 0.01 and 1.2 inches
of water.
* NOTE: For the correct installation of a duct smoke unit, please refer to
To minimize the impact of air turbulence and stratification on
performance, a duct smoke detector should be located as far as
possible downstream from any obstruction (i.e. deflector plates,
elbows, dampers, etc.). In all situations, confirmation of velocity and
pressure differential within specifications is required.

REMOTE ACCESSORIES
the NFPA 72 (National Fire Alarm Code), NFPA 90A (Standard for
Installation of Air Conditioning and Ventilation Systems),NFPA 92A
(Recommended Practice for Smoke Control Systems.), NFPA 5000 (Building
Construction and Safety Code), IMC (International Mechanical Code), and
IFC (International Fire Code).
NOTE: Overcurrent protection device is required in Building
Installation. A switch or circuit breaker is to be included in the building
installation and shall be in close proximity to the duct detector and within easy
reach of the operator and shall be marked as the disconnecting device for the
SL-2000 duct detector.
Audible and visual alarm indicators, remote status indicators, and
remote reset/test switches can be accommodated by the SL-2000
Series duct units by connecting to DC voltage output terminals as
described on Page 4. These terminals are not supervised and the
voltage/current will only be present when the detector unit is in
alarm. The remote pilot (green) LED will be permanently
illuminated when connected to the output terminals as long as input
power and detector head are present.
This detector is not intended for open area protection nor should it be used
for early warning detection or replace a regular fire detection system.

The trouble contacts will not operate in the event of a smoke alarm.
The SL-2000 Series duct detector will operate from various input
voltage sources; namely 24VAC, 24VDC, 115VAC and 230VAC.
SAMPLING TUBES
The operating principle of a duct detector is based on the Venturi
effect. Two tubes extend into the HVAC duct. Air flowing through the
duct is forced into the air intake (inlet) tube via the air intake holes,
(facing the airflow) and passes over the detector head. The air will
be drawn out via the exhaust tube back into the HVAC duct. (A 7”
exhaust tube is provided in the installation kit.) When the
concentration of smoke particles suspended in the air stream reach
the alarm threshold of the detector head, the unit will go into alarm.

MECHANICAL INSTALLATION
LOCATION PREREQUISITES
“NO-TOOLS” TUBE INSTALLATION
This guideline contains general information on duct smoke
detector installation, but does not preclude the NFPA and/or ICC
documents listed. Air Products and Controls assumes no
responsibility for improperly installed duct detectors. To determine
the correct installation position for an SL-2000 Series duct smoke
detector, the following factors must be considered.
The SL-2000 Series duct smoke detector provides a unique,
patented mechanism for installation and/or removal of the
sampling and exhaust tubes from either the front or rear of the
detector housing.
Once the airflow direction has been determined, insert the inlet
and exhaust tubes into the duct smoke detector. If the cover is
in place, the tubes may be inserted into the back of the detector
via the key-slots provided. Simply push the tube into place
against the spring loaded retainer, and turn into the correct
position, allowing the key to “lock” the tube in the desired
orientation.
For front side installation, simply rotate the tube
retainer until the tube may be inserted and oriented properly.
Once the tube is installed, rotate the retainer back into place to
lock down the tube. Ensure air intake sampling tube is positioned
so that the inlet holes are directly facing the airflow.
1) A uniform non-turbulent (laminar) airflow between 100 ft/min.
to 4,000 ft/min. must be present in the HVAC duct. To determine
duct velocities, examine the engineering specifications that
define the expected velocities or use an Alnor model 6000AP
velocity meter (or equivalent).
2) To minimize the impact of air turbulence and stratification
on performance, a duct smoke detector should be located as
far as possible downstream from any obstruction (i.e. deflector
plates, elbows, dampers, etc.). In all situations, confirmation of
velocity and pressure differential within specifications is
required.
Tube Support Hole only for Ducts Greater than 3 Feet Wide
The pressure differential between the input sampling (high
pressure) tube and exhaust (low pressure) tube for the
SL-2000 Series smoke duct detector should be greater than
0.01 inches of water and less than 1.2 inches of water.
DUCT WIDTH
AIR FLOW DIRECTION
3) Identify a code compliant location (supply or return side,
or both) for the installation of the duct unit that will permit
easy access for viewing and serviceability.
4) When installing on the return side, install duct units prior to
the air being exhausted from the building or diluted with
outside “fresh” air.

AIR FLOW
5) When installing duct smoke units downstream of filters,
fires occurring in the filters will be detected, but if the filters
become blocked, insufficient air flow through the duct unit will
prevent the correct operation of the duct detector. Duct units
installed in the supply air side may monitor upstream
equipment and/or filters.
NOTE: Mountings shown
are typical. Detectors can
be installed side, bottom
or top of duct as long as
proper tube operation and
flow/pressure performance
is maintained
6) Where possible, install duct detectors upstream of air
humidifiers and downstream of dehumidifiers.
DUCT PREPARATION
7) To prevent false alarms, the duct detector should not be
mounted in areas of extreme high or low temperatures, in
areas where high humidity exists, or in areas where the duct
may contain gases or excessive dust.
Remove mounting template from the installation kit. Remove
paper backing from the mounting template and affix it to the duct
at the desired location. Using the template as a guide, drill (2)
mounting holes, 3/32” (2.5mm) for the #12 X ½” sheet metal
screws packaged in the installation kit. Drill or punch (2) 1¼”
(32mm) holes for inlet sampling and exhaust tubes, using the
template as a guide. Clean all holes.
SAMPLING TUBE ASSEMBLY
The SL-2000 Series duct smoke detectors employ a specially
notched sampling tube, which must be ordered separately in one
of four standard lengths.

MOUNTING
After securing the sampling and exhaust tubes to the duct smoke
unit, (or initially placing the tubes through the 1¼” holes drilled or
punched in the HVAC duct to accept the inlet sampling and
exhaust tubes and then attaching them to the duct unit), hold the
duct unit assembly in position and use (2) # 12 X ½” sheet metal
screws (packaged in the installation kit) to secure the duct smoke
detector to the HVAC duct sheet metal.
For duct widths of 6” TO 1.0’
For duct widths of 1.0’ TO 3.0’
For duct widths of 3.0’ TO 5.0’
For duct widths of 5.0’ TO 10.0’
Standard sampling tubes are steel tubes with air intake holes
drilled the entire length of the tube. These tubes can be cut to
length and must span at least 80% the width of the duct. Sampling
tubes over 3.0’ must be supported on the opposite side of the duct.
To ensure the correct operation of the sensing tube, the red end
cap (red stopper in installation kit) must be inserted in
the end of the air intake sampling tube. For custom duct widths,
always use the next longest standard size and cut down to the
exact requirement.
AIR SAMPLING VERIFICATION
To ensure correct operation of the duct unit use a Magnehelic
differential pressure gauge, Dwyer 2000 or 4000 Series (or
equivalent) to determine the differential pressure between the
inlet (high side) and exhaust (low side) tubes. The differential
pressure between the two tubes should be greater than 0.01
inches of water and less than 1.2 inches of water.

AIR SAMPLING VERIFICATION (CONT’D)
This duct smoke detector is shipped with a velocity adapter insert, either factory installed (SL-2000-P), or found in the installation kit (SL-2000N). When installed, this adapter will allow the duct detector to operate at extremely low air velocities. To install the adapter, simply insert it into
the slots provided inside the detector housing so that the adapter fits snugly over the smoke detector head. Unless your system is consistently
operating in the slower velocity range (where the adapter is specifically required, SL-2000-N), we recommend that the adapter not be inserted.
If you experience false alarms at higher velocities with the adapter in place, the adapter should be removed. Please use the following chart for
guidance on when the velocity adapter should be used. For reference, the speeds indicated are intended to represent the velocity of air within
the duct under normal operational conditions.

* CAUTION: Do not use looped wire under terminals. Break wire run to provide for proper supervision of connections.
With detector head removed, connect one of the appropriate dedicated power sources to the applicable terminals (see above). Replace
detector head and depress the cover removal switch (SW1) and the unit will be energized. The green pilot LED will be illuminated, and when
pressing the test/reset button (SW2), the red alarm LED will be illuminated. This test confirms the correct basic operation of the duct smoke
unit, excluding the detector head (see functional testing).
In the event of a fire alarm, certain equipment may be required to be shut down. For example, shut down may be achieved by interrupting the
fan supply source to that particular piece of equipment when wired as indicated on Page 4.

TESTING AND MAINTENANCE PROCEDURES
OPERATIONAL TESTING
SMOKE TESTING: Using smoke test canister with testing nozzle
(available from Air Products and Controls Inc. part number TG-2000),
insert the test gas nozzle into the test port on the unit cover. Press can
against cover to release gas into the chamber.
To determine the correct operation of the SL-2000 Series duct smoke
detector, ensure input power is connected and the green pilot LED is
illuminated.
The LED on the detector head of both the ionization and photoelectric
models will flash while the unit is in standby mode. The LED on the
smoke detector head will be permanently illuminated when smoke is
detected and the head is in alarm.
*
CAUTION:
DO NOT SPRAY GAS FOR MORE THAN ½
SECOND. OVERUSE OF TEST GAS FACILITY MAY RESULT IN
DETECTOR CONTAMINATION.
After 15 to 20 seconds the detector head will go into alarm, illuminating
the detector head LED and causing the duct unit functions to operate,
alarm relays will change state, and the alarm related remote
accessories, if attached, will function.
If no test gas is available to conduct functional testing, remove cover
and, while holding down the cover removal switch, blow smoke from a
cotton wick or punk directly at the head to cause an alarm. The alarm
indicator should illuminate within one minute.
Should additional testing also be required for simulated fire conditions,
smoke bombs placed in the duct may not be suited for the particular
detector head (photoelectric or ionization) selected and installed.
Consult the smoke bomb data for proper use and compatibility with
detector type.
Above: The LED will be permanently illuminated when the unit is in alarm.
The S65A ionization detector head (55000-225APO) utilizes a
radioactive source as its means of detection and will detect smoke
particles of between .1 and 1 micron in size.
With the air handling unit shut down (not connected), and the clear
cover removed, press and hold the test/reset button and the cover
removal switch on the SL-2000. The red alarm LED on the circuit
board will be illuminated and the alarm relay outputs will change state.
Using a multimeter set to OHMS (or continuity buzzer function on the
meter) place the meter probes on the following terminals, and ensure
the contacts are closed (continuity) (8-18) and (6-17). When releasing
the test/reset button these contacts will open.
The S65A photoelectric detector head (55000-328APO) operates on
the principle of light scatter and will detect smoke particles of between
1 and 10 microns in size.
When purchasing smoke bombs for additional required functional testing,
ensure smoke particle sizes comply with the criteria as described above.
NOTE: In situations that require a duct smoke detector to be held in an
alarm condition for an extended period of time, the magnet test or smoke
test methods should be used to ensure the detector is locked into alarm.
The trouble contacts (4,15,5) on the SL-2000 detector will not change
state in the event of a fire alarm, operational, or functional testing.
The trouble contacts can be tested by either releasing the cover
removal switch, or depressing the cover removal switch after rotating
the smoke detector head counter-clockwise and removing the
detector head. This action will extinguish the green pilot LED and
cause the trouble contacts to change state, (4-15) will be closed
(continuity) and (5-15) will be open circuit. Replacing the detector
head and rotating it clockwise until it locks, will cause the green pilot
LED to be illuminated and the unit will be operational, terminals (4-15)
will be an open circuit and (5-15) will be closed (continuity).
MAINTENANCE
Each installation location must be assessed on its own merits. If
the protected area is of a very dirty nature then the SL-2000 Duct
unit(s) will have to be checked and cleaned on a quarterly basis or
when cleaning is required.
As a guideline the smoke detector head should be cleaned every six
months or as required. The best methods of cleaning are to vacuum
the detector head thoroughly or to blow the detector head out using
clean, dry compressed air.
FUNCTIONAL TESTING
Once operational testing is concluded the unit requires functional testing
to determine the correct operation of the detector head.
Do not use chemicals or non-conforming air to clean the detector
head housing as this could contaminate the detector head and
damage the casing.
MAGNET TESTING: Place the magnet provided with the installation kit
on top of the housing between the raised sections above the detector
head (as indicated by the arrows on the unit cover). Allow at least five
seconds for alarm initiation. Remove magnet and reset detector.
Sensing tubes must be inspected and cleaned in accordance with
the schedule as determined above, to allow the free flow of air
through both inlet and exhaust tubes.
Consult your local code and AHJ requirements for required
maintenance schedules.
