General Information
The VISTA-32FB provides two bell circuit outputs for operating fire and burglary alarm
notification appliances. Each bell output is rated as follows: 10VDC - 14VDC, 1.7 amps max.,
power limited. Note that the total alarm current drawn from the Aux Power 1, Aux Power 2,
polling loop, Bell 1, and Bell 2 outputs cannot exceed 2.3 amps for battery-independent
operation. Each output has the following options:
•
Class B supervision (style-Y) or no supervision.
•
Selectable to activate by individual zone assignments.
•
Selectable for Confirmation of Arming Ding (1-2 sec. sounding to confirm system has
armed).
•
Selectable to chime when entry/exit or perimeter zones are faulted.
•
Selectable for steady or pulsing output.
•
Selectable for no timeout or timeout of 2-30 minutes.
The optional PS24 Power Supply Module may be used to convert one or both of the VISTA-32FB
12VDC, 1.7A supervised bell outputs to 24VFW, 1.7A supervised bell outputs. The PS24 module
must be used with the optional VISTA-ULKT enclosure kit (PS24 mounts in this kit's enclosure)
and the optional 1451-24 dual 18VAC/30VAC secondary transformer. The PS24 is powered from
the 30VAC winding of this transformer
•
Burglary bell circuits must be programmed for a timeout of 16 minutes or longer.

•
Commercial fire alarm systems require bell or indicating circuits to be supervised.
Bell Circuit Supervision
To supervise bell circuits, do the following:
•
Install a 2K EOL resistor (Model 610-7, supplied) across the last notification appliance
on each bell output to be supervised.
