Installing External Sounders
The VISTA-128FBP/VISTA-250FBP provides two
Notification Appliance Circuits for operating fire and
burglary alarm notification appliances. Each circuit is
rated as follows: 10VDC – 14VDC, 1.7A max., power-
limited.
NOTE:
The total alarm current drawn from
Auxiliary Power 1, Auxiliary Power 2, polling loop, Bell
1, and Bell 2 cannot exceed 2.3 amps for battery-
independent operation.
The outputs has the following options:
•
Selectable for supervision.
•
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 steady or pulsing
•
Selectable for no timeout or timeout of 2-30
minutes.
If you purchased a kit containing the PS24
Power Supply Module, you may use this
module to convert one or both VISTA-
128FBP/VISTA-250FBP 12VDC, 1.7A style-Y
supervised Notification Appliance Circuits to
24VFW, 1.7A style-Y supervised Notification
Appliance Circuits.

•
Burglary Notification Appliance Circuits
must be programmed for a timeout of 16
minutes or longer.
•
Commercial fire alarm systems require
Notification Appliance Circuits to be
supervised.

This control complies with National Fire
Protection Association (NFPA) requirements for
temporal pulse sounding of fire notification
appliances.
Notification Appliance Circuit Supervision
When supervision is enabled, the VISTA-
128FBP/VISTA-250FBP monitors the Notification
Appliance Circuits wiring for open and short circuit
faults while the output is inactive. The system provides
a trouble indication (Zone 970 Bell 1; 971 Bell 2) when
an open occurs; or when a short occurs between the Bell
(+) and Bell (-) terminal wiring, or between the Bell (+)
terminal wiring and earth ground.
The VISTA-128FBP/VISTA-250FBP indicates the
trouble condition regardless of whether the system is
armed or disarmed. The zone displays on the keypads,
reports to the event log, and transmits to the central
station (if programmed) on Partition 1. The trouble is
cleared from the display by entering the user code +
OFF.
Wiring the Alarm Output
The wiring of the Notification Appliance Circuits
depends upon whether you are going to supervise the
circuit or not. Use the appropriate procedure below for
your application.

Use only UL Listed sounding devices for UL
installations.
