DECT PHONE ENTRY SYSTEM

image of colour finishes

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.

The interface is housed in an attractive and discreet ABS plastic enclosure which is designed for wall mounting in any indoor location, preferably next to the telephone line and a power point.

Dimensions: H = 230mm, W = 185mm, D = 45mm
