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.
U
L
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 (–) on the control.

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.
