Key Features:

• Pet Immune Motion Detection: Adjustable processing to ignore pets up to ~40 pounds, so your cat or small dog won’t trigger false alarms. Dual-element PIR and selectable pulse count minimize false triggers while catching human intruders
  
• 40′ × 40′ Coverage: Wide detection coverage for large rooms or hallways. Suitable for 90° corner mounting or flat wall mounting. Walk-test mode can be initiated from the keypad (two-way feature) to easily verify the coverage area
  
• Bright White LED Light: Industry-first integrated LED that serves multiple roles:
  
  • Walk Test Mode: LED lights on momentarily whenever motion is detected (so installer sees coverage pattern)
    
  • Alarm Strobe: During an actual alarm, the high-intensity white LED can flash repeatedly, acting as a visual deterrent and aiding in video verification (illuminates the area for security cameras) 
    
  • Night Light: Programmable via rules – for example, if motion is sensed during certain hours, the panel can command the PIR’s LED to turn on steadily for a preset duration to light a pathway 
    
• Two-Way & Supervised: The PIR receives arming status – it can automatically adjust sensitivity when the system is armed (vs. disarmed). Supervisory check-ins and low-battery reports keep the panel informed of its status
  
• Long Battery Life: Despite the added LED, efficient power usage (and two Lithium AA batteries) ensures long operation. Plus, sleep mode after motion limits reporting rate (to preserve battery during frequent movement)
  

Technical Specifications:

• Detection Pattern: 40 ft × 40 ft coverage, 90° angle. Optimal mounting ~7–8 ft high. Pet immunity effective when mounted 7.5′ high or above, avoiding areas where pets can get close to sensor
  
• Wireless: Elk Two-Way 902–928 MHz. Sensor can receive commands (e.g., enter walk test or activate LED on demand) from the control. Fully encrypted communication
  
• Battery: Two (2) 1.5V AA Lithium batteries (L91 type recommended).
• Battery Life: ~4–5 years under typical conditions (LED usage and motion frequency can impact this). Low battery signal is sent well before depletion
  
• LED Light Output: White LED, high intensity. Configurable via panel (enable/disable alarm strobe, link to rules for night-light function). Provides substantial illumination in a dark room when on (improves camera footage in alarms)
• Dimensions: ~3.5″ H × 2.4″ W × 1.6″ D. White housing. Operating Temp Range: 14°F to 122°F (–10°C to 50°C). Contains tamper switch on back and cover.
