NOTIFIER XAS-1 and XAS-2 XAS Smoke Detector

General

The XAS Air-sampling Smoke Detection system provides a flexible detection solution to meet unique needs of challenging applications found in typical commercial and industrial sites. The XAS solution is well suited to installations where access to the monitored areas is restricted and provides tamper-proof and unobtrusive detection. The ability to mount the device outside the protected area makes it ideal for use in applications such as correctional facilities, transformer vaults, cable tunnels, elevator shafts, and HVAC ducts. The XAS systems actively draw air from the protected area through sampling holes in a pipe network. Sampled air is then filtered before being analyzed by the analog point detectors incorporated in the systems. The XAS system is available in a single zone (Order as XAS-1-US) or dual zone (Order as XAS2-US), and can be used with one or two detectors per system. The systems utilize a high performance aspirator and programmable flow monitoring circuitry. Air flow level is displayed on a ten element bar graph that can be adjusted for high and low flow thresholds, and flow failure is reported as a device fault via relays to the monitoring system. Compatible with NOTIFIER ONYX, FireWarden, and CLIP series Fire Alarm Control Panels.
