Relay Functions
The VISTA-32FB provides a built-in Form C relay with contacts rated at 28VAC/VDC, 2.8
amps max. This relay may be programmed for one of the functions below (determined by
program field 3 61):
• Alarm Activation.
• Trouble/Supervisory Activation.
• 4-Wire Smoke Detector Reset.
• Battery Saver.
These options are described below.
Alarm Activation
(3 61 = 1 or 4): Steady activation in response to an alarm on one, some, or all zones, as
selected in Zone Programming in #93 Menu Mode (refer to the Quick Start Guide). If 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 a third, unsupervised bell output for
supplementary strobes, sounders, etc. when wired to the Aux. Power 1 output or to a
separate power supply as shown in Figure 15-1. 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). This usage might be required for a
common fire and burglary alarm strobe indicator.
When field 3 61=1, the auxiliary relay can also be programmed to give a brief activation for
confirmation of arming (field 3 57) or for entry/exit or perimeter zone faults while Chime
Mode is active (field 3 59).
AUX RELAY
FACTORY DEFAULTS
• Activates for Zones 1-8 alarms
(steady alarm output)
• No timeout
NOTES:
• Use non-polarized indicating
devices
• Wiring is not supervised
• Do not exceed ratings of the
supply used. If Aux. Pwr. 1
output is used, the combined
alarm current drain from Aux.
Pwr. 1, Aux. Pwr. 2, Bell 1, and
Bell 2 cannot exceed 2.3A max.
