Notifier FSP-951T Multi-Technology Smoke & Heat Detector with Base is an advanced intelligent addressable fire detection device designed to provide reliable early warning of potential fire hazards in commercial buildings, industrial facilities, corporate offices, hospitals, hotels, shopping malls, IT parks, warehouses and other critical infrastructure.
Manufactured by NOTIFIER by Honeywell, the FSP-951T combines advanced photoelectric smoke sensing technology with an integrated fixed-temperature thermal sensor, providing dual-mode fire detection in a single intelligent device.
Its photoelectric sensing chamber detects smoke particles generated by a wide range of combustion sources, while the integrated thermal sensor provides fixed-temperature heat detection at 135°F (57°C). This combination enhances fire detection capabilities and provides an effective solution for intelligent building fire safety systems.
Designed for integration with compatible NOTIFIER ONYX and INSPIRE Series Fire Alarm Control Panels, the FSP-951T features intelligent addressable communication that allows the fire alarm panel to identify the specific detector location during an emergency. Its individual rotary decimal address switches simplify device identification, installation, commissioning and maintenance.
The detector supports NOTIFIER FlashScan® communication technology over a two-wire Signalling Line Circuit (SLC), ensuring efficient communication with compatible addressable fire alarm control panels.
Featuring dual LED indicators with 360-degree visibility, low standby current consumption, a modern low-profile design and convenient plug-in installation, the Notifier FSP-951T is suitable for professional fire detection installations requiring reliable monitoring and enhanced building protection.
Whether you are installing a new intelligent fire alarm system or upgrading an existing addressable fire detection network, the Notifier FSP-951T Smoke and Heat Detector offers an advanced solution for commercial and industrial fire safety applications.
