Description
**The SK-PTIR-W is a cutting-edge, multi-criteria fire detector that integrates photoelectric, thermal, and infrared (PTIR) sensors to accurately identify various components of a fire.**
This multi-sensor solution, which replaces the SK-ACCLIMATE, provides superior sensitivity to genuine fires while maintaining strong resistance to false alarms from airborne nuisances. The implementation of multiple sensors and advanced communication capabilities significantly reduces the occurrence of false alarms compared to single-sensor systems. Advanced algorithms optimize the benefits of all four types of sensors, creating an effective detection strategy with enhanced fire sensitivity and minimized interference from nuisance particles.
– **Photoelectric sensor**: Identifies airborne particles associated with smoke.
– **Thermal sensor**: Detects heat and monitors rate-of-rise with a 135°F fixed temperature threshold.
– **Infrared sensors**: Analyze light patterns in the environment to provide additional data for alarm evaluation.
This detector’s capability to filter out specific false alarm triggers, like those from theater smoke, makes it ideal for settings with moderate to heavy nuisance conditions where single-sensor detectors might misfire. The PTIR detector complies with both UL 268 7th edition and UL 521 listing standards, allowing it to signal distinct alerts for smoke and heat. This dual functionality supports local alerts for photoelectric detection and general evacuation alerts based on thermal detection, thus minimizing workflow disruptions in multi-level buildings.
