Elevator Multi-Party Communication System Cable

An elevator multi-party communication system (such as an intercom system and emergency alarm system) requires different types of cables to ensure the system's stability and reliability. Below is an overview of the common cable requirements for an elevator multi-party communication system:

1. Communication Signal Cables:

· Twisted Pair Cables: Used to transmit voice signals or data communication. Typically, shielded twisted pair cables (such as CAT5e or CAT6) are chosen to reduce electromagnetic interference and ensure signal clarity and stability.

· Coaxial Cables: If the system includes video surveillance or requires high-frequency signal transmission, using coaxial cables (such as RG-59) might be more appropriate.

2. Audio Cables:

· Audio Signal Cables: Used to transmit voice signals. These typically use shielded twin-core cables (such as audio cables) to avoid noise and interference.

3. Power Cables:

· Power Lines: Provide power to various components of the communication system (such as intercoms and alarms). Usually, appropriately rated power cables (such as 2-core or 3-core cables) are chosen to ensure their current-carrying capacity meets the device requirements.

4. Emergency Alarm System:

· Alarm Cables: Used to connect emergency buttons and the alarm system. These typically use shielded twisted pair cables or multi-core cables to ensure reliable transmission of alarm signals.
