Selection notes

• The documented specifications apply to the cited manufacturer version. Confirm the supplied hardware, firmware and accessory configuration.
• Rated audio power is separate from electrical input, PoE standard, auxiliary power output and storage capacity. Speaker impedance is not an extra audio-input connection unless the input row explicitly says so. The cited edition explicitly states 64 GB eMMC with 55 GB for audio files. The 4 GB / 1 GB storage of neighbouring models is not inherited. Only the exact original full model and cited manufacturer edition are used. No omitted B, E, T, R, S, /EN, /EU, /BLACK or hardware revision is inferred.
• Readers, locks, power supplies, batteries, licences and other accessories are not assumed to be included. ISD confirms specification, compatibility, supply, price, lead time and local warranty separately.
