Steven1089 0 Posted June 7 Share Posted June 7 Good evening, I am writing to ask you info about the following problem. Today it has been the third time in less then 2 months that my Scantronic alarm started to make an internal sound - maybe a brief external one as well? - and give me the error "Sound Tamper Reset Required". I have performed the Engineer reset correctly all these times, but I was wondering if maybe this error means that I have to change my alarm battery. What do you think? Thanks for your help Steven Quote Link to post Share on other sites
MrHappy 1,939 Posted June 7 Share Posted June 7 a duff battery won't make the bell tamaper go off.. Quote Mr Veritas God Link to post Share on other sites
PeterJames 752 Posted June 7 Share Posted June 7 Tamper fault will be one of the 24 hour circuits to one of your detectors or the bell, the panel and keypad also has a tamper circuit. When was the battery last changed? Not saying it is the battery just asking to find out if its another problem waiting to happen Quote Link to post Share on other sites
sixwheeledbeast 561 Posted June 7 Share Posted June 7 Why does it need an "engineer reset"? Sounds like the external box is duff to me but would need further diagnosis with a meter. Quote Link to post Share on other sites

Not saying it is the battery just asking to find out if its another problem waiting to happen Hi Peter, I think the battery is at least 5 years old (maybe something more, I should ask to the previous house owner). 9 hours ago, sixwheeledbeast said: Why does it need an "engineer reset"?

sixwheeledbeast 561 Posted Tuesday at 08:50 Share Posted Tuesday at 08:50 Well then the battery is also likely duff too. They need regular servicing to be reliable. Checking the tamper return voltage with a DMM would be a start. Quote Link to post Share on other sites
PeterJames 752 Posted Tuesday at 19:08 Share Posted Tuesday at 19:08 Battery should be replaced every 4 years, it is another problem in the waiting. Quote Link to post Share on other sites
Steven1089 0 Posted Wednesday at 08:15 Author Share Posted Wednesday at 08:15 Thanks @sixwheeledbeast and @PeterJames for your kind answers. I was wondering, in the case of a power cut and a duff battery, will I have to re-code/re-install my alarm, or the alarm would be able to keep my settings in memory?

sixwheeledbeast 561 Posted Wednesday at 08:48 Share Posted Wednesday at 08:48 You don't want this to happen in the first place as that would trigger the outside bell hold off when mains and battery are missing. Programming should be stored in non-volatile memory but it can be possible for memory to be lost on older kit if the system is faulty. 1 Quote Link to post Share on other sites
