PA-6600 series is a novel approach to the issue of false alarms and pet tolerance in PIR motion detectors. Through the use of "Twin Dual-Element" mirror optic sensors, we've created ceiling mount detectors with no equal in the security industry.
Using "non-linear" mirror adjustment technology, PA-6600 series ensure maximum performance over a given area on ceilings up to 6m. Twin PIR's are not new but Twin-Mirror-Non-Linear PIR's are. With "rock solid" performance, PA-6600 series offers installers the opportunity to virtually eliminate false alarms from the toughest of environments.
