The BT1 Telephone interface offers the convenience of operating a door entry system from an existing BT style telephone without interfering with its normal usage. Most domestic tone-dialling telephones are compatible with the BT1 including cordless DECT telephones which are of great benefit to those people with limited mobility.
In addition to conversing with a caller at the front door panel the resident may allow them access by operating the lock release directly from their telephone.
