Honeywell PTIR-W Multi-Criteria Photo/Thermal/Infrared Detector

$119.99

The SK-PTIR-W is an intelligent, multi-criteria detector that combines photoelectric, thermal, and infrared (PTIR) sensors in one unit to sense multiple components of a fire. This multi-sensor approach on the SK-PTIR-W (replaces the SK-ACCLIMATE) 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 all four sensor types creating our best detection strategy offering heightened immunity to nuisance particulate and enhanced sensitivity to real fire. • Photoelectric sensor detects airborne particles associated with smoke. • Thermal sensor detects heat and rate-of-rise (135°F fixed temperature threshold). • Infrared sensors discern light patterns in the environment as an additional data point for alarm determination. This ability to reject certain nuisance alarm triggers, such as theater smoke, 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 both UL 268 7th edition and UL 521 listing 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.
