Dual technology motion detector that combines PIR technology with microwave detection is suitable for protection of rooms with sub-optimal 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. This 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,
• microwave antimask feature
• ambient temperature compensation,
• remote test mode and alarm memory features,
• „PET immunity” option
