Section 14: AUXILIARY RELAY
The VISTA-100 provides a built-in "Form C" relay with contacts rated at 28 VAC/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 #93 Zone Programming mode. 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 21. 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).
