NH-200 Series Addressable Heat Detectors for FireWarden Series
The NOTIFIER® NH-200 Series intelligent thermal detectors are
designed for both performance and aesthetics, and are direct
replacements for the NH-100 Series. A new modern, sleek, contem-
porary design and advanced thermal technologies make the NH-200
Series ideal for both system operation and building design. The
point ID address, set using rotary decimal switches, provide specific
detector locations.
Compatible with FireWarden® Series fire alarm control panels, the
series includes a 135°F/57°C fixed-temperature, rate-of-rise, and a
190°F/88°C fixed high-temperature detectors. These thermal detec-
tors provide effective, intelligent property protection in a variety of
applications. Detectors are available for both FlashScan® and CLIP
applications as designated.
Features
SLC LOOP:
• Two-wire SLC loop connection
• Unit uses base for wiring
ADDRESSING:
• Addressable by device
• Rotary, decimal addressing
(Refer to the FireWarden panel manuals for device capacity.)
ARCHITECTURE:
• Designed to meet UL 268 7th Edition
• Sleek, low-profile, stylish design
• State-of-the-art thermistor technology for fast response
• Integral communications and built-in device-type identification
• Built-in tamper resistant feature
• Built-in functional test switch activated by external magnet
OPERATION:
• Fixed temperature model (NH-200) factory preset to 135°F
(57°C)
• Rate-of-rise model (NH-200R),15°F (8.3°C) per minute
• High-temperature model (NH-200H
) factory preset to 190°F
(88°C)
• 360°-field viewing angle of the two visual alarm indicators, LEDs
blink red in Normal condition and turn on steady red in Alarm
• LEDs blink every time the unit is polled
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 maintenance
• Separate base allows interchange of photoelectric, ionization and
thermal sensors
OTHER SYSTEM FEATURES:
• Remote test feature from the panel
• Walk test with address display
• Low standby current
OPTIONS:
• Remote LED output connection to optional RA100Z remote LED
annunciator
• Flanged surface mounting kit
Installation
NH-200 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 detector 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.
When using relay or sounder bases, consult the N100-ISO installation
sheet I56-3625 for device limitations between isolator modules and iso-
lator bases.
Applications
Use thermal detectors for protection of property. For further informa-
tion, refer to I56-6522, Applications Manual for System Smoke
Detectors, which provides detailed information on detector spacing,
placement, zoning, wiring, and special applications.
Construction
These detectors are constructed of fire-resistant plastic. The NH-
200 Series plug-in intelligent thermal detectors are designed to com-
mercial standards and offer an attractive appearance.
Operation
Each NH-200 Series detector uses one of the panel’s addresses
(total limit is panel dependent) on the FireWarden Signaling Line Cir-
cuit (SLC). 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 stimulates its electronics and
reports an alarm. It blinks its LEDs when polled and turns the LEDs
on when commanded by the panel. The NH-200 Series offers fea-
tures and performance that represent the latest in thermal detector
technology.
