PRODUCT OVERVIEW
PRODUCT APPLICATION
HS-100 Series plenum / duct smoke detectors provide early
detection of smoke and products of combustion present in air
moving at no or low ow 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 HS-100 is designed specically for applications where our
standard external mount duct detectors cannot be utilized.
Examples include air shafts, plenum spaces or applications requiring
extremely low or no air velocity ≤ 100 ft/min. A compatible Listed
MS- or MSR- Series remote indicator must be installed in a visible
position with the HS-100.
 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 re
detection system.
PRODUCT DESCRIPTION
The HS-100 Series smoke detector is tted with a mounting
base that will accept an ionization smoke detector head
model 55000-225 or photoelectric smoke detector head
model 55000-328. The duct unit supports one set of form “C”
alarm contacts, one form “A” alarm contact and one form “B”
trouble contact. The trouble contact supervises the presence of
the input power and the removal of the smoke detector head.
The trouble contacts will not operate in the event of a smoke alarm.
The HS-100 Series duct detector will operate from various input
voltage sources; namely 24VAC, 24VDC, 115VAC and 230VAC.
SAMPLING
The operating principle of this duct detector is based on air owing
through the duct and passing over the detector head. 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 spaces
with an air velocity between 0 to 3,000 feet per minute. To verify
correct installation, the air velocity should be measured using a
velocity meter. An acceptable reading is between 0 and 2,000 ft/min
for the HS-100-N; between 0 and 3,000 ft/min for the HS-100-P.
To minimize the impact of air turbulence and stratication on
performance, a duct smoke detector should be located as far
as possible downstream from any obstruction (i.e. deector
plates, elbows, etc.). In plenum space applications, turbulent areas
would be preferred over areas considered “dead spots”, or areas
that do not have active velocity when typical system airow is
present. In all situations, conrmation of velocity is required.
REMOTE ACCESSORIES
Audible and visual alarm indicators, remote status indicators,
and remote reset/test switches can be accommodated by the
HS-100 Series duct units by connecting to DC voltage output
terminals as described on Page 3. 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.

LOCATION PREREQUISITES
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 plenum/duct smoke detectors. To
determine the correct installation position
for an HS-100 Series duct smoke detector,
the following factors must be considered.
1) The airow present at the HS-100 unit
must be a representative sample of the air
moving through the HVAC system (NOT in
a “dead spot”). The airow must be between
0 ft/min. to 3,000 ft/min. To determine
duct velocities for in-duct applications
(shown top right), examine the engineering
specications that dene the expected
velocities or use an Alnor model 6000AP
velocity meter (or equivalent).
To determine fpm velocities in plenum
spaces such as the return in a rooftop
package unit (shown bottom right), divide
the cfm velocity by the plenum space
in square feet at the desired mounting
location of the HS-100 unit (multiply the
linear foot measurement of height by the
linear foot measurement of width). For
example:
30 ton Package Unit puts out 12,000cfm
24in high x 30in wide = 2ft x 2.5ft = 5ft2
12,000cfm ÷ 5 ft2 plenum = 2,400 fpm
2) To minimize the impact of air turbulence and stratication
on performance, a duct smoke detector should be located
as far as possible downstream from any obstruction (i.e.
deector plates, elbows, etc.). In all situations, conrmation of
velocity within specications is required.
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 inspection 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 lters,
res occurring in the lters will be detected, but if the lters
become blocked, insufcient air ow 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 lters.
6) Where possible, install duct detectors upstream of air
humidiers and downstream of dehumidiers.
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.
MOUNTING
Remove the detector from its twist-in base. Remove the two
mounting base plate-to-shroud screws. After securing the
mounting base plate to the 4" square back box, wire the mounting
base plate as appropriate. Re-assemble the shroud/detector base
to the mounting base plate. Re-install the detector head. Proceed
to testing.
When mounted, it is critical that the smoke-sensor is situated
such that the airstream ows through the head and not directly at
the head (see below).

ELECTRICAL INSTALLATION
TERMINAL AND POWER CONNECTIONS
Prior to connecting input power to the duct unit, determine the correct input voltage/current availability and ensure it is connected
to the correct terminals.
WIRING
In the event of a re alarm, certain equipment may be required to be shut down. For example, shut down may be achieved by
interrupting the supply source to that particular piece of equipment when wired as indicated on Page 4.
 CAUTION: Do not use looped wire under terminals. Break wire run to provide for proper supervision of connections.

OPERATIONAL TESTING
To determine the correct operation of the HS-100 Series duct
smoke detector, ensure input power is connected and the LED
on the detector head of both the ionization and photoelectric
models is ashing 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.
Above: The LED will be permanently illuminated when the unit is in alarm.
Cause a detector alarm via magnet or smoke testing procedures
detailed under functional testing below with the air handling unit
shut down (not connected). The red alarm LED on the detector
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) (19-18) and (8-9).
When removing the magnet or clearing the detector chamber of
test gas and twisting the head loose manually and locking it back
into position these contacts will again open and the unit will be
back in the normal standby state.
The trouble contacts (16,17) on the HS-100 detector will not
change state in the event of a re alarm, operational, or functional
testing. The trouble contacts can be tested by rotating the smoke
detector head counter-clockwise or completely removing the
detector head. This action will extinguish the ashing red LED
and cause the trouble contacts to change state, and (16-17) will
be open circuit. Replacing the detector head and rotating it
clockwise until it locks will cause the red LED to be illuminated
ashing and the unit will be operational; terminals (16-17) 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.
MAGNET TESTING: Place the magnet provided with the
installation kit on top of the shroud or detector head roughly
opposite the LED. Allow at least ve seconds for alarm initiation.
Remove magnet and reset detector.
SMOKE TESTING: Using smoke test canister with spray
testing nozzle (available from Air Products and Controls Inc.
part number TG-1000), spray the test gas into the detector.
 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, 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 re
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.
The S65A ionization detector head (55000-225) utilizes a
radioactive source as its means of detection and will detect smoke
particles of between .1 and 1 micron in size.
The S65A photoelectric detector head (55000-328) 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.
MAINTENANCE
Each installation location must be assessed on its own merits. If
the protected area is of a very dirty nature then the HS-100 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.
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.
Consult your local code and AHJ requirements for required
maintenance schedules.
