Common Numbering Schemes

In many buildings the flat numbering does not follow a single sequence as illustrated above;

there are often separate sequences for each floor and each sequence begins with a different

number (e.g. 101.. 201.. ). Most requirements can be achieved by adding an offset address

to each Isolator. This offset enables any start address (i.e. the address of the first flat) to be

set between 1 and 3200.

The offset address is set using dipswitch SW7:

SW7 switch

Offset

Example

[q2e4t6ui]

^ ^ ^

+2 +100 +400

Total offset = +502

1 +1

2 +2

3 +50

4 +100

5 +200

6 +400

7 +800

8 +1600

Simply add the Total offset value of SW7 switches to the addresses selected by SW6 (See

the table on page 33).

Example: First Floor 101-116, Second Floor 202-217:

(+100)

Choose 9-16 then add offset of +100

3 202-209

1, 5 ON

(+201)

Choose 1-8 then add offset of +201

4 210-217

16)

1, 5 ON

(+201)

Choose 9-16 then add offset of +201

Unused phone connections - Important

It may be desirable to use less than eight connections on a given isolator for convenience of

cable or building layout. E.g. if there are 6 flats on each floor: use one isolator per floor.

However it is important that in any numbering scheme there are no duplicate flat addresses

or the corresponding phones may not operate correctly. All unused outputs should

therefore be disabled.
