    Key features
    Wireless capacityA single module recognizes 16 wireless devices; up to 6 sirens, door and IR detectors, panic buttons, and keyfobs count toward that number.
    RangeCommunicates up to 2 km away in open space and uses frequency hopping.
    Zone loopsRecognizes NO/NC, 1EOL, 2EOL, and 3EOL zone loop types and works with 2.7 K, 4.7 K, and 6.8 K EOLR values.
    Relay to the panelConverts data from wireless peripherals into TCP/IP network data and sends it to the wired control panel.
    Secure linkCommunicates two-way and uses AES128 encryption.
    Link and installationStores up to 1024 events when the link drops; the 126.0 mm × 57.0 mm × 33.2 mm electro-galvanized sheet case fits into the panel.
