Replacement cycle & preventive maintenance
Otis bulletin SB-INT-2024-05 recommends:
-
Audio test every 6 months: latency < 200 ms, SPL > 85 dB at 1 m.
-
Network test every 12 months: packet loss < 1 %, PoE voltage 48 V ±2 V.
-
Replace entire intercom every 10 years or 1 million button presses, whichever comes first.
-
Immediate replacement if:
– latency > 200 ms or packet loss > 1 %,
– SPL < 80 dB at 1 m after volume adjust,
– IP address not pingable after power cycle,
– housing cracked exposing electronics.
Pro tip: 70 % of premature failures are traced to loose RJ45 — re-crimp every year.
Maintenance tips from nanjing zhuye elevatorparts
-
Always use shielded CAT5e; unshielded cable picks up inverter noise.
-
Never apply WD-40; it attracts dust and clogs microphone mesh.
-
Keep a spare XAA25301H10 in every service van; at 0.3 kg it costs less than one non-compliance fine.
-
After heavy cleaning, run 10 voice tests and check packet loss = 0.
-
Order the “Intercom Kit” (handset + PoE + CAT5e + calibration certificate) from nanjing zhuye elevatorparts to eliminate parts hunting and ensure matched components.
