Notifier FSP-951-IV Ivory Low-Profile Intelligent Photoelectric Smoke Sensor
The Notifier FSP-951-IV is a low-profile intelligent photoelectric smoke sensor designed for use with compatible Notifier addressable fire alarm systems. Featuring an ivory finish, the sensor combines an advanced photoelectric sensing chamber with addressable-analog communications to provide reliable smoke detection for commercial and institutional fire alarm applications.
The FSP-951-IV transmits an analog representation of smoke density over the signaling line circuit to the fire alarm control panel. This allows the compatible panel to evaluate sensor information and determine the appropriate system response.
Designed for flexible system integration, the FSP-951-IV supports both FlashScan and CLIP (Classic Loop Interface Protocol) operating modes. Built-in rotary decimal switches provide straightforward device addressing during installation and commissioning.
The FSP-951-IV is also listed for use in duct applications, expanding its versatility across a variety of fire detection system designs.
This model is an appropriate replacement for the Notifier FSP-851 when compatibility with the existing fire alarm system has been verified.

Intelligent Photoelectric Detection
The FSP-951-IV combines a photoelectric sensing chamber with intelligent addressable communications. Rather than functioning solely as a conventional standalone detector, the sensor communicates smoke level information to the compatible Notifier fire alarm control panel for system processing.
This architecture provides the fire alarm system with detailed information from individual sensors while allowing each device to have a unique address on the signaling line circuit.
FlashScan and CLIP Compatibility
The Notifier FSP-951-IV supports both FlashScan and CLIP communication protocols, providing flexibility for compatible Notifier fire alarm systems.
Rotary dial switches located on the sensor provide a straightforward method for assigning the device address during installation, replacement, or system expansion.
Duct Applications
The FSP-951-IV is listed for use in duct applications when installed with compatible equipment and according to applicable installation requirements.
With an air velocity rating from 0 to 4,000 ft/min (0 to 1,219.2 m/min), the sensor can support compatible HVAC duct smoke detection applications in addition to standard open-area detection.
Applications
The Notifier FSP-951-IV is ideal for:
-
Commercial buildings
-
