RF Supervision Sounder: Setting this option starts a pulsing keypad trouble sounder.
Valid user code silences sounder in its partition.
RF Low Battery Sounder: Setting this option starts a pulsing keypad trouble sounder.
Valid user code silences sounder in its partition.
System Low Battery Sounder: Setting this option starts a pulsing keypad trouble
sounder. Valid user code silences sounder in its partition. Only partition 1 may be enabled
to send system low battery.
AC Loss Sounder: Setting this option starts a pulsing keypad trouble sounder. Valid user
code silences sounder in its partition. Only partition 1 may be enabled to send AC loss to
the CS (submode 2, Question 73, L3-L4).
Any time the sounder is on, it must be acknowledged with a user code before arming is
allowed. If the system is armed and a trouble sounder starts, entry of a valid user code will
disarm and silence the sounder for that partition. AC loss is a system event and will be
displayed/annunciated in all partitions. Thus if the system is partitioned, each partition's
sounder requires individual acknowledgment with a user code.
