20-Conductor Configuration

The 82222050C contains twenty individual 22 AWG conductors within one cable assembly.

This high conductor count is ideal for compatible multi-station intercom systems where numerous communication, call, and control circuits must be carried between system components.

Using one properly specified multi-conductor cable can simplify installation compared with running multiple smaller cables.

Overall-Shielded Construction

An overall shield surrounds the cable assembly to help protect low-voltage intercom signals from electrical interference.

Shielded cable is especially useful in commercial buildings containing:

• Power wiring

• Lighting circuits

• Motors

• Transformers

• HVAC equipment

• Building automation equipment

• Other electrical systems

Always follow Aiphone's wiring and shield termination instructions for the specific system.

Aiphone LEF Series Applications

The 82222050C is specifically identified by Aiphone for several LEF Series wiring applications.

Typical uses include:

• LEF-10 standard system wiring

• LEF-10C system wiring

• BG-10C to LEF answering-station wiring

• Larger selective-call intercom systems

• LEF systems incorporating door-release functions

LEF-10 Application

Aiphone specifies #822220 cable for standard LEF-10 system wiring.

The LEF-10 is a 10-channel selective-call master station capable of supporting up to 11 total stations in a compatible system.

The 20-conductor cable provides ample conductors for the common wiring and individual station circuits required in larger LEF installations.

LEF-10C Application

The 82222050C is also specified for the:

LEF-10C – 10-Channel Master Station with All Call

This station supports:

• Selective calling

• Hands-free answering

• Door release

• Background music with additional equipment

• All Call with additional equipment

BG-10C Application

For systems using the BG-10C All Call / Chime / Background Music Adaptor, Aiphone specifies up to 19 conductors between the BG-10C and compatible LEF answering station.

Recommended cable:

Aiphone #822220

This makes the 82222050C the appropriate 500-foot cable option for these applications.

LEF Series Wiring Examples

Aiphone specifies the following cable families for various LEF configurations:

• LEF-10 – #822220

• LEF-10C – #822220

• BG-10C to Answering Station – #822220

• LEF-3C – #822212

• LEF-3L – #822212

• Looped Sub Stations up to 8 – #822210

• Door/Sub Station Homerun – #822203

Always verify the system wiring diagram before ordering cable.

Cable Ratings

The 82222050C carries several commercial low-voltage cable classifications:

CL3R – Class 3 riser-rated cable
FPLR – Power-limited fire alarm riser cable
CMR – Communications riser cable
FT-4 – Flame-test classification

Always verify applicable local building and electrical-code requirements.

Aiphone-Approved Cable

Aiphone systems can depend on specific cable characteristics including:

• Wire gauge

• Conductor count

• Shielding

• Capacitance

• Resistance

• Maximum wiring distance

Using manufacturer-specified cable helps maintain system performance and simplifies troubleshooting and future service.

Important Installation Note

The 82222050C is shielded and non-plenum.

Do not substitute it where the installation specifically requires:

• Plenum-rated cable

• Direct-burial cable

• Non-shielded cable

• CAT-5e or CAT-6

• Different wire gauge

• Different conductor count

Always follow the wiring requirements of the exact Aiphone equipment.

Ideal Applications

• Commercial offices

• Schools and universities

• Healthcare facilities

• Government buildings

• Warehouses

• Manufacturing facilities

• Security offices

• Multi-station intercom systems

• Selective-call systems

• LEF Series installations

• Existing Aiphone system repairs

• Intercom system expansions

Aiphone Warranty Advantage

When qualifying Aiphone products are installed using approved Aiphone wire according to manufacturer requirements, the applicable product warranty is extended by one additional year.
