Architectural/Engineering Specification
The air duct smoke detector shall be a Mircom Model
DH100ACDC Series Duct Smoke Detector. The
detector housing shall be UL and ULC listed. The
detector shall operate at air velocities of 100 feet per
minute to 4,000 feet per minute. The unit shall be
capable of controlling up to ten (10) air handling
systems when interconnected with other detectors.
The detector shall be capable of providing a trouble
signal in the event that the front cover is removed. It
shall be capable of local testing via magnetic switch
or remote testing using the SSK451A Multi-Signalling
Accessory or the RTS451KEY Remote Test Station.
The unit shall be reset by local reset button or remote
test station. The duct smoke detector housing shall
incorporate an airtight smoke chamber in compliance
with UL/ULC. The housing shall be capable of
mounting to either rectangular or round ducts without
adapter brackets. An integral filter system shall be
included to reduce dust and residue effects on detector
and housing, thereby reducing maintenance and
servicing. Sampling tubes shall either be telescoping
or be easily installed by passing through the duct
housing after the housing is mounted to the duct. The
unit shall provide a spacial separation of no less than
1/4” and/or a physical barrier between the high and
low voltage terminals. The enclosure shall meets
applicable UL and ULC standards regarding electrical
junction boxes. Terminal connections shall be of the
strip and clamp method suitable for 12–18 AWG
wiring.

Description
Mircom’s DH100ACDC 4-wire duct smoke detector
is available as either an ionization or photoelectric
model. This new design allows for simplified cleaning
and maintenance, or a change in application without
removing the duct housing. The DH100ACDC
samples air currents passing through a duct and gives
dependable performance for management of fans,
blowers, and air conditioning systems, preventing the
spread of toxic smoke and fire gases through the
protected area.
The DH1000ACDCLP features Low-Flow technology
enabling duct smoke detection throughout a broad
range of airflow environments. Many difficult to solve
HVAC applications occur in low airflow duct
applications where reliable smoke detection is critical.
Innoviar with Low-Flow technology can detect smoke
at air speed velocities of 100 feet per minute or greater,
while continuing the same reliable performance to
4,000 feet per minute.
WARNING: Duct smoke detectors have specific
limitations. Duct Detectors are: NOT a substitute for
an open area smoke detector, NOT a substitute for
early warning detection, and NOT a replacement for a
building’s regular fire detection system. Duct smoke
detectors shall be installed in accordance with CAN/
ULC-S524-M91 and CEC Section 32. Refer to NFPA
72 and 90A for additional duct detector application
information.
