NH-100(A) Series
Intelligent Addressable Thermal
Detectors for FireWarden Series
Addressable
DN-6997:D • A1-320
General
The
NOTIFIER NH-100(A) Series thermal detectors are
addressable sensors that use a state-of-the-art thermistor
sensing circuit for fast response. These sensors provide open-
area protection and are intended for use with
FireWarden
Series (FireWarden-100-2 and FireWarden-50) and Spartan
(NSP-25)
addressable Fire Alarm Control Panels (FACPs).
The
NH-100(A) and NH-100R(A) sensors provide fixed tem-
perature alarm detection at 135°F (57°C). The
NH-100R(A)
sensor also responds to rate-of-rise conditions of greater than
15°F (8.3°C) per minute. The
NH-100H(A) is a fixed high-tem-
perature detector that activates at 190°F (88°C). These ther-
mal detectors provide addressable property protection in a
variety of applications.
Two LEDs on each sensor light to provide a local, visible sen-
sor indication. Remote LED annunciator capability is available
using an optional accessory, the RA100Z.
Features
SLC loop:
• Two-wire SLC loop connection.
• Unit uses base for wiring.
Addressing:
• Addressable by device.
• Rotary, decimal addressing: 01 – 99 with FireWarden-100-
2, NSP-25, 01 – 50 with FireWarden-50.
Architecture:
• Sleek, low-profile, stylish design.
• State-of-the-art thermistor technology for fast response.
• Integral communications and built-in device-type identifica-
tion.
• Built-in tamper resistant feature.
• Built-in functional test switch activated by external magnet.
Operation:
• Factory preset at 135°F (57°C) for the NH-100(A) and NH-
100R(A); 190°F (88°C) for the NH-100H(A).
• Rate-of-rise triggers at 15°F (8.3°C) per minute for the NH-
100R(A).
• 360°-field viewing angle of the visual alarm indicators (two
bicolor LEDs). LEDs blink red in Normal condition and turn
on steady red in Alarm.
• Visible LEDs “blink” every time the unit is addressed.
Mechanicals:
• Sealed against back pressure.
• SEMS screws for wiring of the separate base.
• Designed for direct-surface or electrical-box mounting.
• Plugs into separate base for ease of installation and main-
tenance.
• Separate base allows interchange of photoelectric, ioniza-
tion and thermal sensors.
Other system features:
• Remote test feature from the panel.
• Walk test with address display.
• Low standby current.
• 94-5V plastic flammability rating.
Options:
• Remote LED output connection to optional RA100Z remote
LED annunciator.
• Flanged surface mounting kit.
Installation
NH-100(A) Series plug-in intelligent thermal detectors use a
detachable base to simplify installation, service and mainte-
nance. Installation instructions are shipped with each detector.
Mount base (all base types) on an electrical backbox which is
at least 1.5" (3.81 cm) deep. For a chart of compatible junction
boxes, see DN-60054.
NOTE: Because of the inherent supervision provided by the SLC
loop, end-of-line resistors are not required. Wiring “T-taps” or
branches are permitted for Style 4 (Class “B”) wiring only.
Applications
Use thermal detectors for protection of property.
Construction
These detectors are constructed of off-white fire-resistant
plastic. The NH-100(A) Series plug-in intelligent thermal
detectors are designed to commercial standards and offer an
attractive appearance.
Operation
Each NH-100(A) Series detector uses one of 99 (FireWarden-
100-2, NSP-25) or 50 (FireWarden-50) possible addresses on
a control panel SLC loop. It responds to regular polls from the
control panel and reports its type and the status. If it receives a
test command from the panel (or a local magnet test), it stimu-
lates its electronics and reports an alarm. It blinks its LEDs
when polled and turns the LEDs on when commanded by the
panel. The NH-100(A) Series offers features and performance
that represent the latest in thermal detector technology.
