Commercial Video Intercom Expansion | Home-Run Wiring | 7 JP-4HD Station Connections | Cat5e/6 | 24V DC

The Aiphone JP-8Z Video Distribution Adaptor is a professional-grade intercom accessory designed to simplify wiring and expand compatible Aiphone JP Series Video Intercom Systems.

Featuring seven dedicated video sub master station connections, the JP-8Z allows up to seven Aiphone JP-4HD video answering stations to connect directly to a single distribution point rather than requiring traditional daisy-chain wiring.

Designed for commercial offices, schools, healthcare facilities, government buildings, and larger residential properties, the JP-8Z provides a convenient solution for installations requiring multiple indoor video answering locations.

The adaptor connects to the Aiphone JP-4MED Video Master Station using Cat5e or Cat6 cable and distributes communication signals and 24V DC power to the connected JP-4HD sub master stations.

Depending on the number of connected stations, the JP-8Z uses one or two Aiphone PS-2420UL power supplies, allowing reliable operation of expanded JP Series intercom systems.

Its compact design, direct surface-mount capability, and DIN rail mounting compatibility make the JP-8Z an excellent solution for structured commercial intercom installations.

Home-Run Wiring & Power Distribution

1. Centralized Video Intercom Connections

The Aiphone JP-8Z allows multiple JP-4HD answering stations to connect directly to one central adaptor.

This home-run wiring configuration simplifies cable routing and provides a convenient alternative to connecting each sub master station sequentially.

2. Seven Independent Station Connections

The adaptor provides seven dedicated sub master outputs divided into two groups:

Group 1 – Four Sub Master Stations

• Connects up to four JP-4HD stations.

• Uses a compatible 24V DC PS-2420UL power supply.

• Provides centralized power and communication connections.

Group 2 – Three Additional Sub Master Stations

• Connects up to three additional JP-4HD stations.

• Requires a second compatible PS-2420UL power supply when five to seven sub masters are installed.

3. Master Station Integration

The JP-8Z connects to the JP-4MED primary master station using Cat5e or Cat6 cable.

This arrangement allows the connected indoor stations to participate in supported JP Series visitor communication, monitoring, door-release, and internal calling functions.

These functions are provided by the connected intercom stations, not by the distribution adaptor independently.

4. Flexible Commercial Installation

By centralizing the sub master connections, the JP-8Z helps simplify installation in offices, schools, medical facilities, and buildings with multiple indoor answering locations.

5. Expanded System Capability

When used with compatible JP Series equipment, the JP-8Z supports a system consisting of:

• One JP-4MED primary master station

• Up to seven JP-4HD sub master stations

• Up to four compatible video door stations within the complete JP Series system

Installation & Compatibility

The Aiphone JP-8Z is designed specifically for compatible Aiphone JP Series Video Intercom Systems.

The adaptor connects to the JP-4MED master station using Cat5e or Cat6 cable, while each JP-4HD sub master station connects directly to an available distribution output.

The JP-8Z uses one or two Aiphone PS-2420UL 24V DC power supplies to power connected sub master stations. The JP-4MED master station requires its own properly configured power supply.

Mounting Options

• Direct Surface Mount: Installs onto a suitable wall or equipment panel using integrated mounting holes.
