Philips HC-3210/HC-3220 Non-visual Indoor Unit User Manual
The HC‑3210/HC‑3220 indoor units are non‑visual intercom devices with a high‑strength plastic housing, offering basic call functions, anti‑tamper protection, and emergency alarm features. The HC‑3220 model adds a four‑zone anti‑theft system and can be linked with visual units or used independently in villas or large communities.
Installation uses a back‑plane mounting method and a 4‑core communication bus. The units can be expanded to a maximum of four indoor units and two resident door stations, with wiring requirements for shielded twisted‑pair data lines and coaxial video lines. Power is supplied at DC15 V (±10 %). This manual is written in Chinese.
