VISTA-128FBPN Installation and Setup Guide
3-8
Auxiliary Relay Connections
The VISTA-128FBPN 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 3-8.
If field 3
✳61 = 4, the auxiliary relay remains activated until User Code + # + 67 is entered. 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).
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. 2,
BELL 1, AND BELL 2 CANNOT EXCEED 2.3A MAX.

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.
4-Wire Smoke Detector Reset
(3
✳61 = 2) Momentary (8-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 3-9.
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.
