DAX Digital Isolating Exchange

The DAX digital door entry telephone system is designed primarily for large blocks of flats in the public housing sector where a conventional door entry panel may be impractical due to its size. The entrance panel is based on the vandal resistant LCP design and incorporates a large, clear display and well-spaced buttons.

The DAX digital system operates on the Line Isolation principle, which has two advantages over common-wired systems:

• Any malicious damage sustained to an individual telephone or its associated cable will not effect the operation of the rest of the system.
• The telephone conversation between the tenant and the caller is totally private.

System Features

• up to 256 flats and 4 entrances.
• large LED dot matrix display
• 4 digit alpha-numeric flat numbers
• 4 digit coded access facility
• trades and porter facility
• standby battery backup
• outputs for fail-safe and fail-secure releases
