Dual technology motion detector that combines PIR technology with microwave detection is suitable for protection of rooms with suboptimal environmental conditions where drafts or intensive convection may occur. The use of new microwave sensor operating and 24GHz frequency, together with 0402 SMD technology, allowed to design a dual technology device that fits into a typical PIR enclosure. These makes GREY a great choice for protection of rooms with a fireplace or hot-air heating systems, where the appearance of the installation components is of the same importance as their reliability.

• dual detection technology PIR+microwave that ensures reliability even in harsh conditions,
• ambient temperature compensation,
• remote test mode and alarm memory features,
• PET immune mode (up to 15 kg)
• built-in end-of-line resistors (2EOL: 2 x 1.1 kΩ).
