Multi-criteria detection with ASAtechnology from Siemens  Very Early Warning Fire Detector complaint with NFPA 76 (Telco), NFPA 720, and UL 2075  2 thermal, 2 optical and 1 CO sensor  Operating temperature range of 32°F to 120°F  Programmable supervisory temperature warning (32°F to 120°F)  9 selectable temperature and 26 selectable environment settings  No False Alarm Guarantee  Green detection (no ionization and RoHS compliant) 1st detector in the U.S. with dual optics, forward backward, light scattering for highly sensitive detection ASA or Advanced Signal Analysis is a dynamic algorithm that continually adjusts

What makes detectors with ASAtechnology unique? Two IR light sources 1 2. Scattered light from smoke (Forward & Backward) 2 3.Optic Receiver 3 Patented labyrinth 4 Two redundant temperature sensors measure the temperature 5 Monitored CO sensor measures the CO concentration 6 Only Siemens offers UL listed Forward and Backward Light Scattering Detection

Siemens FireFinder XLS provides unrivaled interface with VESDA fire detection  Compatible with most VESDA-NET devices  100 VESDA detectors on VESDA-NET  Up to 4000 VESDA detectors per FireFinder XLS panel

Typical Application with Siemens and VESDA  Single point of control to view/control any VESDA detector  Reduces complexity and cost –no monitor modules required  4 Levels of Alarm, detailed fault codes, scan signals, obscuration levels appear at user interface  No need for VESDA displays
