INSTALLATION AND MAINTENANCE INSTRUCTIONS
FOR SM-501 SERIES DUCT SMOKE DETECTORS
PRODUCT OVERVIEW
PRODUCT APPLICATION
SM-501 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.
NOTE:For the correct installation of a duct smoke unit, please refer to
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).
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.
PRODUCT DESCRIPTION
The SM-501 Series smoke detector is fitted with a mounting base that will
accept an ionization smoke detector head model 55000-225 (or 55000-
250) or photoelectric smoke detector head model 55000-328 (or 55000-
350). The duct unit supports two sets of form “C” alarm contacts and one
form “C” trouble contact. The trouble contact supervises the presence of
the input power and removal of the detector head.
THE TROUBLE CONTACTS (TERMINALS13-14, 15)
ARE SHOWN IN THE NON-ENERGIZED CONDITION. IN
NORMAL OPERATION,CONTACTS WILL BE REVERSED.
The trouble contacts will not operate in the event of a smoke alarm.
The SM-501 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.
The duct smoke detector units are designed to operate in duct widths
from 6” to 10’ wide with an air velocity between 500 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.
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
Audible and visual alarm indicators, remote status indicators, and
remote reset/test switches can be accommodated by the SM-501 Series
duct units by connecting to DC voltage output terminals 16 through
21. 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.

SM-501 – Installation

MECHANICAL INSTALLATION
LOCATION PREREQUISITES
This guideline contains general information on duct smoke detector
installation, but does not preclude the NFPA and/or ICC
documents listed. No responsibility is assumed for the
improper installation of the duct detectors. To determine the correct
installation position for an SM-501 Series duct smoke detector, the
following factors must be considered.
1. A uniform non-turbulent (laminar) airflow between 500 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.
The pressure differential between the input sampling
(high pressure) tube and exhaust (low pressure) tube
for the SM-501 Series smoke duct detector should be
greater than 0.01 inches of water and less than 1.2 inches
of water.
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.
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.
6. Where possible, install duct detectors upstream of air humidifiers
and downstream of dehumidifiers.
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.
SAMPLING TUBE ASSEMBLY
Sampling tubes are to be ordered separately in one of four standard
lengths.
STS-1.0 For duct widths of 6” to 1.0’
STS-2.5 For duct widths of 1.0’ to 3.0’
STS-5.0 For duct widths of 3.0’ to 5.0’
STS-10.0 For duct widths of 5.0’ to 10.0’
FAST TUBE Sectional Tube for duct widths up to 8.0’
Standard sampling tubes are steel tubes with air intake holes drilled
the entire length of the tube. FAST Tubes are a recognized plastic with
an open slot along the length. These tubes can be cut to length and
must span at least 80% of the duct width (spanning the entire width is
suggested).
Sampling tubes over 3ft must be supported on the opposite side of the
duct. To ensure correct operation of the sampling tube, the red end cap
(red stopper in installation kit) must be inserted in the end of the air
intake. For custom duct widths, always use the next longest standard size
and cut down to the exact requirement.
Once the airflow direction has been determined, insert the inlet and
exhaust tubes into the sampling tube connectors fitted to the back of
the duct smoke detector which are equipped with set screws. These
connectors will allow the tubes to be correctly orientated and secured
by tightening the set screw. Ensure air intake sampling tube is positioned
so that the inlet holes (or FAST Tube slot) directly face the airflow.
DUCT PREPARATION
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 (4) mounting holes
(3/32” diam.) for the # 12 X 1/2” sheet metal screws packaged in the
installation kit. Drill or punch (2) 1 3/8” holes for inlet sampling and
exhaust tubes, using the template as a guide. Clean all holes.
MOUNTING
After securing the sampling and exhaust tubes to the duct smoke unit,
(or initially placing the tubes through the 1 3/8” 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 (4) # 12 X 1/2” sheet metal screws (packaged in the
installation kit) to secure the duct smoke detector to the HVAC duct
sheet metal.
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.

SM-501 – Installation

OPERATIONAL TESTING
To determine the correct operation of the SM-501 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 (55000-225 or 55000-328) will flash while the unit is in standby mode.
The LED on the detector head of both the ionization and photoelectric
models (55000-250 or 55000-350) will not flash while the unit is in the
standby mode. The LED on all the above detector heads will be permanently
illuminated when smoke is detected and the head is in alarm.
With the air handling unit shut down (not connected), and the clear cover
removed, press and hold the test/reset button on the SM-501. 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) (8-9) and (11-12). When releasing the
test/reset button these contacts will open.
The trouble contacts 13, 14, 15 on the SM-501 detector will not change
state in the event of a fire alarm, operational, or functional testing. The
trouble contacts can be tested by 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, (13-14) will
be closed (continuity) and (14-15) 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 (13-14) will be an
open circuit and (14-15) will be closed (continuity).
FUNCTIONAL TESTING
Once operational testing is concluded the unit requires functional testing to
determine the correct operation of the detector head.
With the clear cover removed, air handling unit shut down, and using the
aerosol test smoke gas part number TG-1000, spray the test gas directly at
the detector head from a distance of 12 inches for 2 seconds.
 CAUTION: SPRAYING FROM A DISTANCE CLOSER
THAN 12 INCHES MAY CAUSE DETECTOR CONTAMINATION.
TESTING PROCEDURES
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, light a piece of clothesline
(rope) and blow the flame out, hold the smoldering rope 3” from the detector
head and lightly blow across the smoldering area towards the detector head,
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.
S65A ionization detector head 55000-225 and S60A ionization detector head
55000-250 utilize a radioactive source as its means of detection and will detect
smoke particles of between .1 and 1 micron in size.
S65A photoelectric detector head 55000-328 and S60A photoelectric detector
head 55000-350 operate 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.
MAINTENANCE
Each installation location must be assessed on its own merits. If the protected
area is of a very dirty nature then the SM-501 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 vaccum the
detector head thoroughly or to blow the detector head out using clean, dry
compressed air.
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.
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.
Above: The LED will be permanently illuminated when the unit is in alarm.
Above: For factory recommended functional testing, spray the proper test
gas directly at the detector head from a distance of 12 inches for 2 seconds.
