Gabs Posted July 7, 2017 Share Posted July 7, 2017 I have just got a new Modern Security Systems bell box, made by Elmdene, dated 1992, however when power is applied, both sirens will sound very quietly, not at full power t all. Is this a problem with the bell box, or the wiring? I just put 12V into the Hold Off and it started sounding very quietly. Does anyone know if this has SAB/SCB functionality, or is it just SAB? If it is SCB, i know that it is the batteries that are the problem, I just need to change it back to SAB somehow, if this is the case. Thanks In Advance Quote Link to comment Share on other sites More sharing options...
norman Posted July 7, 2017 Share Posted July 7, 2017 Could be the batteries dragging it down, but I'd take the engineer link out first and try again. Quote Nothing is foolproof to a sufficiently talented fool. Link to comment Share on other sites More sharing options...

I tried that, and it made no difference. I'll try removing the batteries and try it again. It's a nice bell box, shame Modern are no longer around. What does the Engineer link do? Just now, james.wilson said: looking the pcb it don't look the best I know, that was my concern, it may be damaged beyond repair. I'll have a go at removing the batteries and try it again Quote Link to comment Share on other sites More sharing options...
The Arab Posted July 8, 2017 Share Posted July 8, 2017 If you're just putting power on are you holding the tamper switches down as from memory the things sounded when you put power on till the tamper switches are closed, also watch the big white paddles as they were for anti foam and caused nothing but hassle so slide them off Quote Trade Member Link to comment Share on other sites More sharing options...

Yeah, they are are... Sadly. Do you think to get the volume of it up, I could use something like this: http://www.ebay.co.uk/itm/LM386-Super-Mini-Amplifier-Board-Module-3V-12V-Kit-Red-Led-Light-Blue-PC-Board/252628203210?_trksid=p2047675.c100005.m1851&_trkparms=aid%3D222007%26algo%3DSIM.MBE%26ao%3D2%26asc%3D44779%26meid%3D597b9836e54d40ae8cef13a9609a3762%26pid%3D100005%26rk%3D6%26rkt%3D6%26sd%3D332261893488 I am thinking of it. 20 hours ago, norman said: Could be the batteries dragging it down, but I'd take the engineer link out first and try again.

MrHappy Posted July 8, 2017 Share Posted July 8, 2017 shouldn't a young man like you be drinking cider or sniffing glue in the park ? its old tat but try- close the 3 tamper switches - bolt, bottom & back leave the 2 anti foam switches open add hold off voltage, with tampers close it should be silent if so, wire link from rtn to & it should ring ?

Well, I go out with my friends, don't worry... I'm not THAT sad I tried all of that, but it didn't really work. Do you have any idea where I could get a Eurobell module?
