Key Features:

• Wide-Angle Motion Detection: 40 ft range, 90°+ field of view – ideal for wall placement to cover large rooms or corridors. Detects motion of a human intruder crossing the zone
• Pet Friendly: Can be set with pulse count or placed to avoid pets up to ~40 lbs. Reduces false alarms by requiring multiple pulses (heat changes) before triggering if desired
  
• Easy Installation: Mounting bracket included for flat wall or corner mounting. The sensor clips into the bracket securely and has a tamper switch to alert if it’s pried off.
  
• Battery Efficient: Runs on one high-capacity CR123A lithium battery, providing roughly 5–7 years of operation. The device will report low battery to the panel to prompt replacement
  
• System Integration: Works seamlessly with ELK 319 one-way wireless receivers or compatible 319.5 MHz panels – each motion sensor is a supervised zone with alarm memory and trouble reporting
  

Technical Specifications:

• Coverage Pattern: Broad 40′ × 40′ coverage when mounted at ~7.5′ height. Curtain coverage down to floor; optimal detection of movement perpendicular to sensor (side-to-side motion)
  
• Battery: One (1) CR123A 3V lithium battery. User Replaceable: Yes, via front cover (panel will alert when battery is low)
  
• Tamper Protection: Yes – cover tamper switch. Any removal of the sensor from its mounting or opening of the case sends a tamper signal
  
• Frequency: 319.5 MHz. Transmits alarm, tamper, supervision, and low battery signals to the control.
• Dimensions: 3.2″ H × 2.4″ W × 1.7″ D. White housing. Operating environment 32–120 °F (0–49 °C) indoor
