Key Features:

• Honeywell 5800 Compatibility: Supports all unencrypted 345 MHz Honeywell 5800-series wireless devices (doors, windows, PIRs, panic buttons, keyfobs, etc.) – enabling easy takeover of existing wireless sensors
  
• High Zone Capacity: Handles up to 144 wireless zones via one receiver (mapped into zone slots on the M1). Multiple receivers (up to 9) can be installed to improve coverage in large installations
  
• Data Bus Powered: Connects to the M1’s RS-485 data bus just like a keypad or zone expander – making installation and addressing straightforward (set via DIP switches)
  
• Dual Antennas: Two whip antennas for reliable RF reception (diversity reception reduces dead spots). Typical open-air range is 300–500 feet line-of-sight for transmitters
  
• Simple Enrollment: Wireless sensors are enrolled into the M1 using ElkRP software or via keypad learning mode, similar to enrolling zones on a Honeywell system. Tamper switches on the receiver provide supervision if the cover is opened or unit is removed.
  

Technical Specifications:

• Frequency: 345 MHz one-way (compatible with Honeywell/Resideo 5800 and some 2GIG sensors)
• Zones: 144 wireless zones per receiver (zone numbers assignable in blocks); up to 9 receivers can share the load or extend coverage
• Connection: 4-wire data bus (12VDC, A, B, GND). Address set via DIP – occupies one “expander” address on the M1
• Current Draw: ~70 mA from panel aux power. Backup battery recommended on panel for power outage coverage
• Dimensions: Approximately 5″ × 3″ PCB; comes with a plastic mounting case and hardware (anchors, screws) for wall mounting near panel. Operating temp 32–120 °F
