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.
