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 flow 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 specifically 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 fire
detection system.
PRODUCT DESCRIPTION
The HS-100 Series smoke detector is fitted 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 flowing
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.

PRODUCT OVERVIEW
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, 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 airflow is
present. In all situations, confirmation 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.
