Notifier, Multi-Criteria Detector, Photo/Thermal/Infrared FPTI-951
The Notifier FPTI-951AUS are plug-in addressable multicriteria detectors that replace the FAPT-851AUS Series. They combine photoelectric, thermal, and infrared (PTIR) sensors in one unit to sense multiple components of a fire. This approach enables enhanced sensitivity to real fire with heightened immunity to nuisance particulates.
Multiple sensors and communication can greatly reduce nuisance alarms compared to single sensing methods. Sophisticated algorithms maximize the advantages of the sensor types. This detection strategy offers heightened immunity to nuisance particulates and enhanced sensitivity to real fire.
- Photoelectric sensors detect airborne particles associated with smoke
- Thermal sensors detect heat and rate-of-rise 57 °C fixed temperature threshold.
- The Infrared sensor discerns light patterns in the environment as an additional data point for alarm determination.
This ability to reject certain nuisance alarm triggers supports the use of the detector in applications where moderate to heavy nuisance conditions exist that might cause single sensing detectors to trigger a false alarm.
The PTIR detector meets AS 7240.7 and AS 7240.5 standards requirements and can indicate distinct smoke and heat alarms. This dual nature supports a local alarm setting for photoelectric detection and a general evacuation setting based on thermal detection. This can minimize work interruptions in multi-level buildings.
