* Note:
Remove these shunts to eliminate background music for each zone individually (except Single Amplifier Mode).
IMPORTANT:
Electronic devices are susceptible to lightning and power station electrical surges from both the AC
outlet and the telephone line. It is recommended that a surge protector be installed to protect against such surges.
Step 1.
Set the
RING TRIP/TRUNK/PAGE PORT
switch to the
RING TRIP
position (all the way to the left).
Step 2.
Set the
TALK BATT
switch to the
OFF
position (all the way to the left).
Step 3.
Attach
TIP
and
RING
to the
TELCO IN
screw terminals.
Step 4.
Attach the background music source, if used, to the
MUSIC IN
screw terminals.
Step 5.
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 timer is up, and if
the timer is set for too short a time, 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 busy signals or periods of silence more 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, hook up a pair of wires from
the phone system night ring output to the
NIGHT RING
screw terminals.
Step 7.
Dial tone and page alert tone may be enabled as shown in DIP switch programming.
