•
Do not set any keypads to address 31
(nonaddressable mode). They will interfere
with other keypads (as well as other
devices) connected to the keypad
terminals.
•
If an “OC” or “OPEN CIRCUIT” message is
present on a keypad, data from the control
is not reaching the keypad. Please check
your wiring.
Supplementary Power Supply to Power Additional
Keypads
When the control’s auxiliary power load for all devices
exceeds 750mA, you can power additional keypads from
a regulated 12VDC power supply (e.g., ADEMCO
AD12612 (1.2A)). Use a UL Listed, battery-backed
supply for UL installations.
Connect the additional keypads as shown in Figure 3-5,
using the keypad wire colors shown. Be sure to observe
the current ratings for the power supply used.
•
Make connections directly to the screw
terminals as shown in
Figure 3-5. Make no
connection to the keypad blue wire (if
present).
•
Be sure to connect the negative (–) terminal
on the power supply unit to terminal 7 (–) on
the control.

Installing External Sounders
The VISTA-128B PLUS provides a bell circuit output
for operating fire and burglary alarm notification
appliances. The alarm output is rated as follows:
10VDC – 14VDC, 1.7A max., power-limited.
UL
•
For Household Fire and combination
Household Fire/Burglary installations, the
total current drawn from the auxiliary power,
polling loop, and alarm output combined
must not exceed 750mA.
•
For Household Burglary installations, the
total current drawn from the alarm output
must not exceed 1.7A. A battery must be
installed, as it supplies the current for the
combined auxiliary power, polling loop, and
alarm output in excess of 750mA.
The output has the following options:
•
Selectable for supervision.
•
Selectable for confirmation of arming ding.
•
Selectable to chime when entry/exit or perimeter
zones are faulted.
•
Selectable for no timeout or timeout of 2-30
minutes.
UL
Burglary bell circuits must be programmed for
a timeout of 16 minutes or longer.
UL985 Household Fire or Combination Household
Fire/Burglary Installations
For installations that must provide UL Listed
protection, the total combined current drawn from the
alarm output, auxiliary power output, and polling loop
must not exceed 750mA in order to comply with the
battery independence requirements. If, for example,
two System Sensor PA400 piezo alarm sounders, wired
in parallel, are used (24mA total), then 726mA (750mA
– 24mA) is available for auxiliary output and polling
loop use.
UL1023 Household Burglary Installations
For Household Burglary installations, the total current
drawn from the alarm output must not exceed 1.7A. A
battery must be installed, as the battery supplies
current from the combined auxiliary power, polling
loop, and alarm output in excess of 750mA.
Non-UL Installations
For non-UL installations, the total current drawn from
this output can be up to 1.7 amps. A battery must be
installed, as the battery supplies current in excess of
750mA. Up to two 719 sirens can be used wired in
parallel.
UL
This control complies with National Fire
Protection Association (NFPA) requirements
for temporal pulse sounding of fire notification
appliances.
