Paging is accessed from any telephone by pressing the CO line button (EKSU & KSU), or dialing the number assigned to paging. Twelve (12) individual
zones are selected by dialing 01 thru 12. All Call is selected by dialing 00. The four (4) zone groups are selected for group paging, by dialing 21 thru 24.
When any zone, zone group, or all call selection is made, a page alert tone will be heard at all the speakers in the selected zone, zone group, or all
zones (if all call is selected). The tone will also be heard at the paging telephone to provide verification of connection to the selected speakers.
The ZC-312 provides one zone group (3 zones) and can be expanded to 4 zone groups (12 zones), by adding up to 3 plug-in ZEM-3 zone expansion
modules as shown in Chart 1 and Figure 1.
