The HX-40DAM is a high mount, outdoor PIR / MIcrowave detector with Anti-Masking for use under severe environmental conditions where reliability and performance is a must. It includes all the same features as the HX-40AM, with the exclusive Microwave Area Shaping Technology and Optex designed gold plated antenna. The added microwave technology and features allow unrivaled quality and ability to achieve highly reliable detection performance. The unique pyro-element developed by Optex provides a multiple pattern detection with 94 high density detection zones and accurate discrimination function for spot temperature changes of moving objects. These features drastically reduce fales and missed alarms caused by severe outdoor environmental changes and provide a wide range of applications. Accurate detection performance is necessary is such environments, and the HX-40DAM meets these requirements.
