allows the horn relay to serve as another level A1, level A2, level A3 or both. Individual channel alarms
may also be configured to not affect the Horn relay on a channel by channel basis.

Turning Acknowledge set to Yes allows the Horn relay to be deactivated during alarm conditions by an
Alarm Reset. This is useful if an audible device is being driven by the relay
4.5.2.10 Failsafe
Failsafe controls relay activation for this relay. Failsafe set to Yes causes the horn relay to de-energize
during alarm conditions and energize when there is no alarm. Thereby, a power failure forces the relay
contact to the alarm position.
4.5.2.11 Piezo Alarm
Piezo Alarm On causes the audible piezo to duplicate the action of the horn relay. This feature may be
used to provide a low decibel indication of the status of the system's horn.
