Installation
1 - 20 ADPRO FastTrace, Issue 5
1.17 General Alarm Relay Output
A Form C single pole changeover contact set is available on the rear panel. If configured to do so, the General Alarm
relay activates while the ADPRO FastTrace has an alarm active. The contacts will remain in the changeover condition
until all alarms are reset.
Ratings: Switching Voltage = 32VDC maximum
Switching Current = 1Amp maximum
Isolation = 32V maximum
The relay may also be configured to activate whenever the unit is connected via a network or data link to the Remote
Viewing Software (e.g. ADPRO Video Central). This feature may be used (for instance) to notify a third-party alarm
system when ADPRO FastTrace activity is taking place.
1.18 Audio Connections
Audio functionality is provided via two connectors on the ADPRO FastTrace. The functions available are compatible
with the ADPRO VM22A Audio Switchers.
