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, 10MHz-1GHz). It delivers a 12m detection range, 110 degree 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).

Key Features
12m/110 degree dual-element PIR coverage with Fresnel optics for reliable indoor detection
True temperature compensation - stable performance under changing ambient temperature
3-level adjustable pulse counting - balance sensitivity vs. RF-interference resistance per site
Anti-RF and anti-white-light interference, tested to 20V/m (10MHz-1GHz)
Selectable NO/NC alarm output - compatible with most conventional alarm panels
Independent NC tamper output for enclosure protection
Wall or corner mount, SMT-manufactured for consistent quality control
Low MOQ (100pcs), 5-day lead time, OEM/private label available

Installation Guidelines
Mount on wall (height 1.7-2.5m) 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 about 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
