The document summarizes an intelligent, multi-sensor fire detector called the AD355(A) ADAPT detector. It has the following key features:
1. It uses a combination of photoelectric and thermal sensing technologies to automatically adjust its sensitivity without needing programming by a control panel.
2. It has a microprocessor in the detector head that processes alarm data and adjusts sensitivity based on the environment.
3. It is compatible with LiteSpeed and CLIP communication protocols to provide fast response speeds between detectors and control panels.
