SES ALRJ71C Telco Interface Block for Alliance Voice Processor Line Cards
The SES ALRJ71C telco interface block is a Select Engineered Systems wiring and termination accessory used in Alliance telephone access installations. It provides a practical interface point for telephone-style wiring tied to the Alliance line card arrangement, helping keep building phone-line connections organized inside the access-control system cabinet or associated wiring area.
This part is most often needed during service work on older apartment, condominium, office, and multi-tenant telephone access systems where one line card serves multiple resident phone connections. It should be selected by the existing board label or parts list, not by appearance alone, because SES Alliance components work together as a specific system family.
The ALRJ71C is not a replacement for the ALXLC line card or ALXLEP line expansion panel. It supports the wiring side of the system and should be installed only after the technician confirms the phone-line count, card location, and original SES wiring plan.

Technician Note
Confirm whether the service issue is with the interface block, line card, expansion panel, or field wiring. A bad phone-line connection can look like a board problem when the trouble is actually in the terminal block, punch-down wiring, or tenant phone wiring.
Before Ordering
- Match the original SES part number ALRJ71C.
- Verify the system is an Alliance / Alliance Voice Processor installation.
- Confirm the number of line cards and the location of the block being replaced.
- Photograph and label existing telco wiring before disconnecting anything.
- Do not substitute a generic telco block unless the SES wiring layout supports it.
Professional Advisory
Telephone access wiring can involve active telecom circuits and building-wide resident phone wiring. For multi-tenant buildings, use a qualified access-control technician familiar with SES Alliance systems.
Product Questions & Answers
Is the ALRJ71C a complete line card?
No. The ALRJ71C is a telco interface block. The ALXLC is the related line card used for phone-line capacity in the Alliance system.
What SES system is this part commonly associated with?
It is commonly associated with Select Engineered Systems Alliance / Alliance Voice Processor telephone access systems.
Can I use this on a CAT or TEC telephone entry system?
Do not assume that fitment. Use the ALRJ71C only where the installed SES system or parts list calls for the Alliance telco interface block.
Why does the wiring need to be checked before replacement?
Older telephone entry systems are often modified in the field. Correct wire position matters for resident phone routing and call operation.
Does this part fix no-dial or no-call problems by itself?
Only if the interface block or its connections are the problem. Line card, processor, phone-line wiring, and programming issues can create similar symptoms.
