My father has an old Spartan SP-600F. The neighbors have complained that when he was on vacation the alarm sounded for 20 minutes before the siren went off. I checked the "Bell Shut Off Time" in progrom location 88 and it is set to "3" which should translate to 6 minutes. We tried a number of different settings but the minimum time we got the siren down to was 14 minutes (We used a VOM to test the siren, we didn't disturb the neighbors).
Any one have any ideas? Should we just spring for a new box?
Thanks.
