A. Initiating a Page
1. Ring Trip Paging
To access the ZPI-4 for ring trip paging, call the C.O., Centrex number or PABX/KSU station number the ZPI-4
is connected to. The ZPI-4 will answer on the first ring, produce dial tone (if enabled) and await Touch Tone entry
for 10 seconds. If there is a Touch Tone entry, the ZPI-4 activates the selected zone(s). If there is no Touch Tone
entry in 10 seconds, the ZPI-4 disconnects.
2. Paging from an Unused Phone System Trunk Input
To make a page with the ZPI-4 installed on a spare trunk port, simply access the trunk connected to the ZPI-4.
The ZPI-4 will produce dial tone (if enabled), wait for Touch Tone entry, and activate the selected zone(s) when it
sees a Touch Tone entry.
3. Paging from a Phone System's 600 Ohm Paging Port
To page in this situation, access the phone system's paging port. The ZPI-4 will detect that a page is being initiat-
ed and wait for a Touch Tone entry. When it sees an entry, it activates the selected zone(s).
B. Selecting Zones
1. Selecting Zones with One ZPI-4
Enter a single Touch Tone to select the zone
or zones to be paged. After this entry has
been made, the ZPI-4 activates the selected
zone(s). See diagram to the right.
2. Selecting Zones with Multiple ZPI-4's
To page all zones, enter a Touch Tone "0". The
ZPI-4 will activate all zones to which it is con-
nected. Otherwise, enter two Touch Tones,
with the first selecting which ZPI-4 is being
addressed, and the second selecting which
zones connected to that ZPI-4 are to be
paged. If a Touch Tone "1" is entered as the
first digit, the Master is selected. If a Touch
Tone "2" is entered as the first digit, the Slave
is selected. See diagrams to the right.
C. Paging
After there has been a Touch Tone entry, the ZPI-4 activates the selected zones and produces a paging alert tone. At
this point the page can be spoken into the handset of the phone. In a RING TRIP or PAGING PORT WITHOUT CON-
TACT CLOSURE application, it is necessary to keep in mind that there is a time limit on the page, set by the TIME
OUT ADJUSTMENT. Also, in these two applications, the VOX voice detect circuit will disconnect the page if three sec-
onds of silence elapse during the page. When finished paging, simply hang up.
