BT Telephone Door Entry Systems
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. All types of domestic telephones are compatible with the BT1 including cordless DECT telephones which are of great benefit to those people with limited mobility. The interface may also connect onto a telephone switchboard (PABX).
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.
