Vista 20 - Alarm Sounded in middle of night and turned off on its own.

I have an ademco vista 20 with a 6150 keypad. Have had it for about 3 years. In the middle of the night last night, the alarm sounded for about 15 seconds, then turned off on its own. There was no record of anything happening on the keypad...in fact it still had the red light as if it was armed and ready....And nobody called us from the headquarters. So it's as if nothing happened, but I can't figure out why the alarm sounded.



Anyone heard of this before or have any ideas what may have caused this?

A passing emergency vehicle that sounded like your siren?

As the previous poster said, it is possible that your panel TLM setting (telephone line monitor) is set for "alarm if armed". What this means is, IF the panel is armed, AND the phone line goes out, the panel will sound the siren. It won't send anything, just blow the horn (the idea being I guess that if someone cuts your phone line, the siren will scare them off).
