Xtralis XCC Class C Aspirating Smoke Detector

Key Features
EN54-20 Class C compliant
Absolute smoke detection
Clean air barrier for optics protection
Single pipe inlet


The Xtralis Class C (XCC) detector is specifically designed to provide a convenient solution for meeting the requirements for a normal sensitivity EN54-20 Class C aspirating smoke detector (ASD).

The XCC offers cost effective normal sensitivity aspirating detection making it ideal where an ASD is needed to overcome the limitations of point detectors. The XCC provides support for flexible ASD pipe network designs to meet the needs of a wide range of environments. When smoke is difficult to detect due to high ceilings and other factors, XCC’s active sampling provides reliable protection. Maintenance access difficulties can be avoided by positioning the detector at ground level or outside the protected area. Discreet capillary air sampling provides unobtrusive detection where ‘invisible’ protection is required. In dirty environments, the XCC helps to reduce nuisance alarms through discrimination between dirt and smoke. In addition, its clean air barrier protects the detection chamber optics for reduced maintenance and longer detector life.

The XCC detector can cover up to 1600m2 and supports up to 18 holes. Each hole is designed to meet EN54-20 Class C requirements and can be used in place of normal point detection with total confidence. The XCC provides two levels of alarm for reliable indication of fire to assure life safety and/or asset protection for your business, using a simple interface to fire alarm control panels and monitoring systems via relays.
