Key Features:

• Ultra-Slim Design: Small, low-profile wireless contact – perfect for discreetly securing doors, windows, drawers, etc. (Sensor measures only a few centimeters long)
  
• Reliable 319.5 MHz RF: Uses ELK’s 319 MHz one-way protocol, fully supervised by the panel. Long RF range and strong battery life ensure dependable performance across your property
  
• Full Supervision: Reports open/close status, tamper (if cover removed), low battery, and sends supervisory check-in signals so the panel can supervise its presence
  
• Easy Installation: Includes double-sided tape and mounting screws. Magnet can be placed up to ¾″ away from sensor. Simply enroll the transmitter serial into the panel and attach to the protected opening
• Battery-Powered: Runs on two (2) CR2032 coin cell batteries (included and user-replaceable) for convenience. The sensor sends a low-battery alert to prompt timely replacement

Technical Specifications:

• RF Frequency: 319.5 MHz (works with ELK-319 series receivers/panels and Interlogix/ITI protocol systems)
  
• Magnet Gap: Supports up to 3/4″ gap between sensor and magnet for reliable closure detection (smaller gaps improve sensitivity)
  
• Dimensions: Transmitter approx. 2.25″ × 1.0″ × 0.3″; Magnet 1.0″ × 0.25″ × 0.25″ (mini form factor for tight mounting spaces)
