Key Features:

• Pattern Recognition™ Audio Sensing: Dual-stage listening – it listens for actual glass-break patterns across the full audio band (low-frequency flex + high-frequency shatter) and uses built-in algorithms to confirm real breaks. Minimizes falses from jingling keys, etc.
  
• 20 ft 360° Coverage: Omni-directional microphone covers all glass within ~20 ft (line of sight). One unit on a wall or ceiling can protect many windows in a room (ideal for living rooms with bay windows or commercial storefronts)
  
• Two-Way Wireless & LED Indicators: Communicates with the panel’s two-way transceiver – which allows features like remote testing.
• LED indicators: Red LED on front activates during alarm (and can be used in manual testing); an internal bi-color LED (viewable with cover off) shows RF acknowledgement and status 
  
• Tamper Supervision: Cover tamper switch will alert the system if someone removes the detector’s cover (attempting to disable it). The device also sends periodic supervisory check-ins to ensure it’s online
  
• Flexible Mounting: Can be wall-mounted or ceiling-mounted. For best performance, position within 20 ft of the glass being protected, with line of sight. (Avoid mounting in noisy kitchens or bathrooms to reduce falses)
  

Technical Specifications:

• Glass Types Detected: Plate, Tempered, Laminated, and Wired glass within specified thicknesses (e.g. plate 3/32″–1/4″, tempered 1/8″–1/4″, etc.). Not intended for glass block or unframed glass
  
• Coverage Range: Rated: 20 feet (6 m) radius in all directions. (For larger rooms, multiple detectors may be needed.) Minimum 4 ft from glass (for accurate sound recognition)
  
• Battery: One (1) CR123 3V lithium battery.
• Battery Life: ~5 years. Low battery condition communicated to panel when battery is nearing depletion
  
• Frequency: 902–928 MHz Elk two-way wireless. Encrypted communication. Device supports OTA firmware updates if needed (flash memory on board)
• Dimensions: 4.25″ W × 3.13″ H × 1.7″ D – sleek, rounded rectangle housing (white). Mounting screws included. Operating Temp 32–120 °F.
• Testing: Recommend using FG-701 simulator or Elk-601 test mode for verifying detection
