The Athenalarm AT-805 is a wired indoor PIR (Passive Infrared) motion sensor for conventional intrusion alarm systems. It uses a dual-element pyroelectric infrared sensor with Fresnel lens optics, true temperature compensation, 3-level adjustable pulse counting, and anti-RF interference protection (20V/m, 10MHzâ??1GHz). It delivers a 12m detection range, 110° detection angle, selectable NO/NC alarm output, and a dedicated NC tamper output.
Suitable for residential, office, retail, warehouse and factory security. Available for wholesale, bulk order, and OEM/private label (MOQ 100pcs, 5-day lead time, 1-year warranty).

Installation Guidelines
Mount on wall (height 1.7â??2.5m) or corner; surface must be solid and vibration-free
Position so intruders cross the detection field rather than walk directly toward the sensor
Avoid: outdoor use, direct sunlight, HVAC vents, heat sources, rotating fans, unstable surfaces, or areas with pets
After power-up, allow ~60s self-test, then perform a walking test to confirm alarm response before commissioning
Recommended: weekly walking test for ongoing system verification
Applications
Residential (homes, villas) · Commercial (offices, retail, malls) · Industrial (factories, warehouses, storage) · Conventional wired alarm system integration projects
