Sense Keypad does not always announce alarm trigger

Aha, so it happened today. In span of 2 days, I set the system to Away 3 times, all from the keypad. When I came home and triggered the alarm, the first two times it announced no problems. The third time, it didn’t announce right away. However, I paid more attention this time and realized that there was an announcement but after alarm triggered. So it could be a delay in the announcement. Does the keypad get a signal from base station of when to make the announcement? Could it be that it’s a latency issue? I did submit a log with id 558716
