All Call Paging Utilizing a Merge/Isolate Cabinet
Merge/Isolate (M/I) cabinets contain switching relays that are energized by a control signal from
Page/Party
®
stations. When energized, the relays merge (connect together) the page lines of multiple
Page/Party
®
systems. This allows voice pages to be broadcast from all the systems connected to the M/I
cabinet. ICS handset stations with the All Call feature contain a push-button switch on the front panel for
activating an M/I cabinet. Refer to Figure 8.
