Supplementary Power Supply for Additional Keypads
When the control’s auxiliary power load for all devices exceeds 1A, you can power additional keypads from a regulated
12VDC power supply. Use a UL Listed, battery-backed supply for UL installations. For fire applications, the power
supply must be UL1481 Listed.
Connect the additional keypads as shown in
Figure 3-9
, using the keypad wire colors shown. Be sure to observe the
current ratings for the power supply used.
UL
For UL commercial fire and burglary installations, no more than one wire per terminal may be connected.
Use only 14-22AWG wire.
•
Make connections directly to the screw terminals as shown in
Figure 3-9
.
•
Be sure to connect the negative (–) terminal on the power supply unit to terminal 7 (

Installing External Sounders
The VISTA-32FBPT provides two Notification Appliance Circuits for operating fire and burglary alarm notification
appliances. Each circuit is rated as Special Application for Fire and 10VDC – 14VDC, 1.7A max. power-limited for
Burglary.
NOTE:
The total alarm current drawn from Auxiliary Power 1, Auxiliary Power 2, polling loop, Bell 1, and Bell 2 cannot
exceed 2.3A (for Canada 1.95A) for battery-independent operation.
The outputs have the following options:
•
Selectable to activate by individual zone assignments
•
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.
You may use a Commercial Fire Listed 24VDC Power Supply to convert one or both VISTA-32FBPT 12VDC,
1.7A style-Y supervised Special Application Notification Appliance Circuits to 24V, style-Y supervised, Special
Application Notification Appliance Circuits.
