To acknowledge receipt of the alarm, press "555" at any time during the recorded message.

This only acknowledges receipt, the alarm condition still exists.

Sensaphone alarm sequence:

When the power goes off, Alarm 2 waits 10 minutes, then issues an alarm status.

It then waits 5 further minutes to begin calling numbers on the list. There is a 1 minute pause between phone number calls.

Upshot: We currently do not know of a power outage until a minimum of 15 minutes after it happens.
