Utilizing a sealed thermistor sensing circuit, the NH‑100R activates upon reaching a factory-set threshold of 135°F (57°C), making it ideal for spaces where smoke detection may be unsuitable—such as kitchens, mechanical rooms, or dusty industrial areas. It communicates with Notifier’s FireWarden and NSP-25 series control panels via the SLC loop, offering precise addressability through rotary switches. Its low-profile design, 360° visible dual LEDs, and support for remote testing make the NH‑100R both highly dependable and service-friendly. Key Features: Fixed-Temperature Detection: Activates at 135°F (57°C), providing consistent thermal response in high-heat or particulate-heavy environments. Addressable SLC Communication: Uses intelligent signaling to communicate alarm and status data to compatible Notifier panels. Rotary Address Switches: Enables panel-specific device addressing (01–99) for location accuracy and simplified programming. 360° Visible LEDs: Dual bi-color indicators blink green when polled and glow solid red in alarm, enhancing visibility from all directions. Low-Profile Plug-In Design: Installs quickly into standard Notifier bases, allowing for easy removal and maintenance. Sealed Construction: Protects internal components from air pressure and contaminants, increasing detector longevity. Remote Test & LED Support: Offers remote panel-based testing and a terminal for optional RA400Z remote annunciator connection. Environmental Performance: Operates from –4°F to 100°F (–20°C to 38°C), with up to 93% non-condensing relative humidity. Legacy Replacement: Supersedes the earlier NH-100 model in many system configurations. The Notifier NH‑100R delivers dependable thermal detection where smoke detectors may not be practical, combining addressable technology, robust construction, and flexible mounting in a compact form factor. Though now replaced by newer models, it remains a solid choice for legacy Notifier systems requiring heat-based fire detection.
