2. Paging from an Unused Phone System Trunk Port
Note:
In this mode, the
ZPI-4
’s time out and VOX sensitivity are disabled. The
ZPI-4
will release the trunk
as soon as the paging party hangs up.
3. Paging from a Phone System’s 600 Ohm Paging Port
Step 1.
Set the
RING TRIP/TRUNK/PAGE PORT
switch to the
TRUNK/PAGE PORT
position (all the way to the right).
Step 2.
Set the
TALK BATT
switch to the
ON
position (all the way to the right).
Step 3.
Attach the unused trunk port to the
TELCO IN
screw terminals.
Step 4.
Attach the background music source, if required, to the
MUSIC IN
screw terminals.
Step 5.
If the phone system provides a contact closure for night ring, connect a pair of wires from this closure to the
NIGHT
CONTACTS
screw terminals. If the phone system provides ring signal for night ring, hook up a pair of wires from
the phone system night ring output to the
NIGHT RING
screw terminals.
Step 6.
Dial tone and Page alert tone may be enabled as shown in
DIP Switch Programming
.
Step 1.
Set the
RING TRIP/TRUNK/PAGE PORT
switch to the
TRUNK/PAGE PORT
position (all the way to the right).
Step 2.
Set the
TALK BATT
switch to the
OFF
position (all the way to the left).
Step 3.
Attach a pair of wires from the paging port to the
TELCO IN
screw terminals.
Step 4.
Attach the background music source, if required, to the
MUSIC IN
screw terminals.
Step 5.
If the phone system provides a page dry contact closure for paging, connect a pair of wires from this closure to the
INPUT
CONTACTS
screw terminals of the
ZPI-4
. In this application, the
ZPI-4
’s time out and VOX sensitivity are disabled. The
ZPI-4
will release the page port as soon as its
INPUT CONTACTS
open.
If the phone system does not provide a page dry contact closure, adjust the
TIME OUT ADJUST
as required (adjustable from
approximately 5 seconds to 80 seconds). This should be set to a second or two longer than the longest expected page. The
ZPI-4
hangs up when this time is reached, and if the timer is set too short, the
ZPI-4
will hang up in the middle of a page.
Notes:
The
VOX SENSITIVITY
probably will not have to be adjusted unless the
ZPI-4
is disconnecting in the middle of a page,
before the time out or there is a period of silence during a page longer than three seconds and the
ZPI-4
does not auto-
disconnect.
To adjust the
VOX SENSITIVITY
, turn the POT counter clockwise to decrease the VOX sensitivity and clockwise to increase
it. The
VOX SENSITIVITY
should be increased if the
ZPI-4
is auto-disconnecting in the middle of pages, and decreased if it is
not auto-disconnecting on periods of silence longer than three seconds.
Step 6.
If the phone system provides a contact closure for night ring, connect a pair of wires from this closure to the
NIGHT
CONTACTS
screw terminals. If the phone system provides ring signal for night ring, connect a pair of wires from
the phone system night ring output to the
NIGHT RING
screw terminals.
Step 7.
Put DIP switch
4
to
OFF
to disable the
ZPI-4
’s dial tone.
Note:
You must be able to send Touch Tones through the PABX’s paging port for this mode to work.
