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., powerlimited. 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 batteryindependent 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 VISTA128FBP/VISTA-250FBP 12VDC, 1.7A style-Y
supervised Notification Appliance Circuits to
24VFW, 1.7A style-Y supervised Notification
Appliance Circuits.

UL
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 VISTA128FBP/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.

Supervising the Notification Appliance Circuits
To wire the NAC using the supervision feature, perform
the following steps:
Step
1
2
Action
Install a 2K EOL resistor (Model 610-7,
supplied) across the last notification
appliance on each Notification Appliance
Circuit to be supervised.
Program Zone 970 (Bell 1) and zone 971 (Bell
2) with a response type of 19 (24-Hour
Trouble).
Disabling the Supervision of the Notification
Appliance Circuits
To install the NAC and disable the supervision feature,
perform the following steps:
Step
Action
1
Cut the white jumpers W1 (for Bell 1) and W2
(for Bell 2) on the main PC board.
2
Program Zone 970 (Bell 1) and zone 971 (Bell
2) with a response type of 00.
The Notification Appliance Circuits will not
respond unless the zones are assigned to them.
For fire alarms, the system displays “FIRE ALARM
SILENCED.” This message also displays if the
Notification Appliance Circuit is not supervised.
Auxiliary Relay Connections
The VISTA-128FBP/VISTA-250FBP provides a built-in
Form C relay with contacts rated at 28VAC/VDC, 2.8A.
The relay may be programmed (field 3✳61) for one of
the following functions:
•
Alarm Activation
•
Trouble/Supervisory Activation
•
4-Wire Smoke Detector Reset
•
Battery Saver
Alarm Activation
(3✳61 = 1 or 4) Steady activation in response to an
alarm.
If field 3✳61 = 1, the auxiliary relay remains active
until Aux. Relay Timeout expires or until User Code +
OFF is entered. This option can be used to provide an
unsupervised Notification Appliance Circuit for
supplementary strobes, sounders, etc. when wired to
the Aux Power 1 or a separate power supply, see Figure
3-7.
If field 3✳61 = 4, the auxiliary relay remains activated
until User Code + # + 67 is entered. This option can be
used for elevator recall or ventilator shutdown on fire
alarms. By default, the relay is set to activate on alarm
zones 1-8 with no timeout (field 3✳61 = 1).
When field 3✳61 = 1, the auxiliary relay can be
programmed to give a brief activation for confirmation
of arming ding (field 3✳57) or Chime Mode (field 3✳59).

Figure 3-7: Wiring Auxiliary Relay for Alarm Activation
Trouble/Supervisory Activation
(3✳61 = 0) Steady activation in response to any zone or
system related trouble condition or to any fire
supervisory condition. The auxiliary relay remains
activated until all fault conditions have been corrected
and a User Code + OFF is entered.
Battery Saver
(3✳61 = 3) When this option is selected, the auxiliary
relay is normally activated (e.g., N.O. and pole contacts
are connected) and de-activates 4 hours after the start
of AC Loss. Using this feature, non-critical loads, such
as supplementary keypads, can be disconnected from
the auxiliary power outputs, allowing a smaller
capacity battery to be used. The relay re-activates
within a few seconds after the AC power restores.
4-Wire Smoke Detector Reset
(3✳61 = 2) Momentary (6-second) activation in response
to a second entry of a User Code + OFF sequence
following a fire alarm condition. This interrupts power
to 4-wire smoke detectors connected to hardwired zones
1-8 and polling loop zones, allowing the detectors to be
reset. Power to the detectors should be wired to the
auxiliary relay and to Aux. Power 1 output, see Figure
3-8.
