Two Problems: Speech and Alarm

Intercom audio is a two-way trade-off: the louder the door-station speaker, the more the microphone picks it up. We tune speaker and mic placement together to keep calls feedback-free, while alarm sounders follow the opposite rule — as loud as the margin requires, placed so wiring loads stay legal. The wiring calculator below keeps your total impedance inside amplifier limits.

Speaker Wiring Impedance
Parallel: total Z = Z₁/n — check it stays above the amplifier minimum. Series: total Z = Z₁ × n. Power per speaker ≈ amp power × (Z total load share).
