On analog Alarm Panels, it's possible to set an ALARM DELAY which is quite a good feature to have in order to avoid waking up the neighborhood with false alarms.
When an armed sensor is triggered, we set the panel to have a 15 second delay before alarming.... and during this delay period, the panel would beep repeatedly indicating it's about to go off and ring all alarms/sirens etc etc.... This gives the user a chance to cancel it if it was triggered by accident. On most occasions when user is unsure what caused the alarm, user would cancel it first, but keep the panic button on hand.... user would then investigate and if it's a legit situation, user will manually trigger the real alarm sounds.
I would like to mimic this behavior and experience on Hubitat.
