System Sensor SS-PTIR Addressable Photoelectric / Thermal / IR Smoke Detector with Base

Description

SS-Series smoke detectors are intelligent (addressable) detectors with point ID capability. Each detector’s address is set with rotary address switches for exact device locations. SS-Series detectors support current SK, LiteSpeed™ and SS Protocol systems. Refer to the Addressable Detector and Sounder Base Compatibility Chart or the Intelligent Control Panel SLC Wiring Manual for specific panel compatibility. Detector sensitivity is continually monitored and reported to the fire alarm control panel. The modern design and expanded color options support contemporary aesthetic demands. Each detector is constructed for exceptional installation and
maintenance efficiency.

The System Sensor SS-PTIR is an intelligent, multi-criteria detector incorporating photoelectric, thermal, and infrared (PTIR) detection principles. Advanced algorithms maximize the advantages of each sensor type creating a more robust detection strategy rejecting nuisance sources, but still responding quickly to real fires. By using multiple sensors and communication between the sensing elements, nuisance alarms can be greatly reduced when compared to single-sensing methods.
• Photoelectric sensors detect particulate in the air associated with smoke
• The thermal sensors detect heat including its rate-of-rise with a 135°F fixed temperature threshold
• The Infrared sensor discerns light patterns in the environment as an additional data point for alarm determination

Because it rejects certain nuisance alarm triggers, the PTIR detector is ideal for applications where moderate nuisance conditions exist. For example, single-sensing detectors might trigger a false alarm on transient cigarette smoke or a quick burst of steam. 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.
