Might have been, taken any of them down recently? I would try to design the circuit like that, just don't want to damage my panel, if it goes wrong. I have built a few Security-Related circuits recently, Don't know anywhere that would sell old stock SABs Quote Link to comment Share on other sites More sharing options...
MrHappy Posted November 21, 2018 Share Posted November 21, 2018 modules started to become old hat in early 90's when interga's ect came to the market with 20min cut off timer (£10 but out stock) Quote Mr Veritas God Link to comment Share on other sites More sharing options...

Looks quite advanced for one. I will just have to try trial and error for my design, I have one, but it would only be one time use, as it wouldn't be charged up again Quote Link to comment Share on other sites More sharing options...
sixwheeledbeast Posted November 21, 2018 Share Posted November 21, 2018 All the SAB modules I used in the past where dipped, surprised to see one without. Should have a 15 minutes cut off to conform, you don't want the council charging you for getting a summons to silence your bell. The basic circuits on Ron's site are not designed to connect to intruder style bells, maybe adapt the circuit so the relay contact sinks a -ve via the alarm panel when coil is active? The other feature bells have is they self activate when the tamper is opened (hence the term Self Activating Bell). If you are going basic with the charging you could use a LM317T to set the voltage then use a 1 Watt resistor in series like you say. Issue being it will only keep the battery "a float" while the battery is charged. To charge a battery that has been drained you ideally need a constant current with a higher voltage than operational voltage; it would take forever or may not fully recharge otherwise.

Looks like a thin sprayed coating I recal recall aritech ones filled with resin Dragon ? with thin coating & ADE one with a even thiner coating Google images have very few pic of bell mods Quote Mr Veritas God Link to comment Share on other sites More sharing options...
