I would suggest it is compatible then if you already have a working 730.
re delay options see below (copied from install manual)
4.4.5 Abort Time (fig. 4.4 location 05)
Do not use in UL installations.
Here you select the length of time allowed by the system to
abort an alarm (not applicable to alarms from FIRE, 24H
SILENT, EMERGENCY, GAS and FLOOD zones). The
PowerMax+ is programmed to provide an “abort interval”
that starts upon detection of an event. During this interval,
the buzzer sounds a warning but the siren remains inactive
and the alarm is not reported. If the user disarms the
system within the allowed abort interval, the alarm is
aborted.
Available options: 00s, 15s, 30s, 45s, 60s, 2m, 3m, 4m.
