DBA-8Z 8 Way Zone isolator

The DBA-8Z Isolator is used to distribute wiring to a ‘zone’ of up to 8 flats whilst providing

isolation from other zones. This isolation ensures that a cable fault within one zone will not

affect the operation of phones within any other zone. It offers a good compromise between

equipment cost and ease of maintenance. If greater isolation is required please refer to the

DBA-4I Phone Isolator.

There is a maximum of 2 phones in each flat. Adding a 2

phone / extension phone reduces

the maximum number of flats that can be powered from the same Power supply.

Isolator PCB’s are normally supplied in an individual ABS plastic enclosure, but can be

supplied in multiples in a lockable IP55 Steel cabinet (with or without power supplies). All

control equipment must be placed in a protected indoor environment.
