Optex HX40 3rd Party Kit – High Mount PIR

How is it used?

We use the third party Optex HX40RAM High Mount Detector for Patios and other outdoor areas where furniture or obstacles would obstruct the standard (low mount) Pet Friendly PIR detection area. The HX40 is installed high enough to detect movement over the top (on the other side) of obstructions ensuring intruders do not pass by undetected


  • Form C alarm out and tamper output
  • Battery saving timer function
  • Active IR digital anti-masking function
  • Mounting height 2.5 – 3m (8ft. – 10ft.)
  • Intelligent and detection logic
  • Double conductive shielding
  • Dual signal processing circuit
  • Vegetation sway analysis logic
  • Ideal detection area setting


The HX-40RAM is a high mount, wireless ready, outdoor detector for mid level to high end applications where reliability and performance is a must. This wireless-ready, battery powered version works with most manufacturer’s wireless systems and allows installers to save valuable installation time and labour costs because no trenching, conduit or cabling is required. 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 fails 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-40RAM meets these requirements.
