The RY-PA 12 VDC Door Release Relay with Normally Open Dry Contact from Aiphone is used in the LEF Series Hands-Free Selective Call System. Each door to be released requires a separate RY-PA Door Release Relay. This relay can also be used in the LDF, NDR, and TB-M/D Intercom Systems. In addition, the RY-PA can be used to activate a doorbell or buzzer when a call is received at the VC-K Handset in the VC-M Series Multi-Tenant Audio Entry System.
