Zoning Configuration.
The INTERCALL system features comprehensive zoning facilities which can cope with most zoning requirements.
The principle of zoning is to enable calls to be displayed only in the area from which they originate. This could be
achieved by installing separate systems but this does not provide 'master' displays where all calls can be shown or the
ability to display emergency 'crash' calls throughout the building to alert other members of staff.
With the INTERCALL system, the zoning is configured and controlled by the display units. They have terminals for
the zone switch and built in menu functions, which are used to configure the zone requirements. When a system is
zoned, we must concentrate on the call point addresses and disregard the text that is associated to that address as this
will need to be re-programmed when the system is commissioned.
Additional Equipment Required.
If a system is to be zoned, you will need to re-program the text. See page 57 Custom Configuration for more
information. If the zoning configuration is to be changed by the staff (e.g Day/Night operation) we will need a zone
switch or time switch for automatic switching.
Call Points
When a system is zoned, we effectively have call points in separate groups which are to be treated as the zones. (See the
diagram above) All the call points in each group must have consecutive addresses.
Display Units
We also have displays arranged in groups these are called display addresses. All displays in the same group must be
set to the same display address. The zone switch is connected to one display in each group, this display is the master
display for that group.
Zone Switch
The Zone Switch is simply a closing contact, which is connected to the chosen master display for each display
address group. It may be a simple manual switch, time switch or automatic closing contact. If the contact is open
circuit, then all displays in that display address group are ‘global’ and they will respond to all call points on the
system. This ‘global’ mode is often used as one of the zone settings.
Display Address Windows
The mechanism by which the zoning is programmed at the LCD Displays, is based around three address windows,
these are called ‘Zone A’, ‘Zone B’ and ‘Zone C’. Each address window has a ‘Lower Address’ setting and a ‘Higher
Address’ setting. When the ‘Zone Switch’ is operated, it selects either global (all addresses) or one of the three address
windows. Pages 35 and 44 detail the connections to be made on the LCD Display units which select the address
window which that group of addresses will use. Page 59 details the setting of the address windows ‘Zone A’, ‘Zone
B’ and ‘Zone C’.
Display Menu - Display Address 00.
There are 16 available display addresses from 00 to 15. When display address 00 is used, the settings for the address
windows ‘Zone A’, ‘Zone B’ and ‘Zone C’ are set up individually on all displays. This allows displays to be controlled
by a single switch, but to have different address window settings.
