General
NOTIFIER ND-100 and ND-100R Intelligent Photoelectric
Smoke Duct Detectors provide
low-flow technology that
enables duct smoke detection throughout a broad range of air-
flow environments in HVAC applications. The low-flow technol-
ogy can detect smoke at air speed velocities of 100 feet per
minute (0.5 m/sec) or greater, while continuing the same reliable
performance to 4,000 feet per minute (20.32 m/sec). The intelli-
gent low-flow duct detectors sample air currents passing
through a duct and gives dependable performance for shutdown
of fans, blowers, and air conditioning systems, preventing the
spread of toxic smoke an fire gases through the protected area.
ND-100 and ND-100R are used exclusively with the NOTIFIER
FireWarden Series addressable control panels. ND-100 and
ND-100R provide a remote alarm output for use with auxiliary
devices, such as the RA400Z(A) remote LED annunciator, as
well as remote test capability with the RTS451(A) or
RTS451KEY(A) Remote Test Stations. The ND-100R features a
Form-C relay.
Applications
Duct smoke detectors have specific limitations, they are:
•
NOT a substitute for open area smoke detectors.
•
NOT a substitute for early warning detection.
•
NOT a replacement for a building’s regular fire detection sys-
tem.

guide,

Features
• Air velocity rating from 100 to 4,000 feet per minute (0.5 to
20.32 m/sec).
• Patented telescopic sampling tube.
• Easily accessible code wheels for addressing detector.
• Outside mounting tabs.
• Mounts to round or rectangular ducts from 1' to 12' (0.3 to 3.7
meters) wide.
• Transparent cover for convenient visual inspection.
• Powered outputs for remote LED, and remote test and
sounder.
• Two Form-C auxiliary contacts (ND-100R).
• Patented cover-tamper trouble signal (ND-100R).
• ND-100R requires both com line power and one of the follow-
ing: 24 VAC/VDC or 120/220 VAC for operation.
Installation
Refer to installation manuals for control panel and duct detector
for detailed information or to install equipment. Installation man-
uals for detectors: I56-2853-000R for ND-100, I56-2854-000R
for ND-100R.
Wiring: For signal wiring (the wiring between detectors or from
detectors to auxiliary devices), it is recommended that single
conductor wire be no smaller than 18 AWG (0.821 mm²). The
duct smoke detector terminals accommodate wire sizes up to 12
AWG (3.31 mm²). Flexible conduit is recommended for the last
foot (30.48 cm) of conduit; solid conduit connections may be
used if desired.
Smoke detectors and alarm system control panels have specifica-
tions for Signaling Line Circuit (SLC) wiring. Consult the control
panel specifications for wiring requirements before wiring the
detector loop. The detectors are designed for ease of wiring; their
housing provides a terminal strip with clamping plates.
LED Features: If programmed with the system control panel,
two LEDs on each duct smoke detector light to provide local vis-
ible indication.
Programming specifications/requirements for intelligent
system control panels: The number of devices that can have
their LEDs programmed to illuminate is limited by the features of
the panel and the individual devices. The actual number of
devices is determined by the control panel and its ability to sup-
ply LED current. Refer to the control panel installation manual
for details.
