sixwheeledbeast Posted March 22, 2020 Share Posted March 22, 2020 Certainly wouldn't recommend buying an expander card for such an old panel, but that's up to you. I am all for good well maintained systems avoiding the e-waste but throwing decent money at obsolete kit is where I'd draw the line. 1 Quote Link to comment Share on other sites More sharing options...

Ok in that case for a dog stint it's ok as if it doesn't work it can be returned Then other choice as swb says you will have to upgrade which is inevitable Quote Link to comment Share on other sites More sharing options...
CR Alarms Posted March 24, 2020 Author Share Posted March 24, 2020 Hi all, just thought I'd let you know i got the sounder tampers working correctly by rtfm, i was very easy it only involved cutting a link in the first unit and linking the tamper series to the second unit tamper return. Now both Sounders if tampered self activate and trigger a full alarm at the panel as it should very loud indeed! Before when the second unit was wired to zone 8 it would only trigger the internal sounder, i imagine this is what you meant about it not being correct. Anyway zone 8 is now spare for what i need, i probably won't bother with the expansion card as i don't foresee myself adding anything else. Just thought i would give you an update. Thanks again all and stay healthy. Quote Link to comment Share on other sites More sharing options...
CR Alarms Posted April 7, 2020 Author Share Posted April 7, 2020 Hi again, i was just wondering out of curiosity if it is acceptable to switch the modes on my sounders the other way round, so the front unit is now scb and the back is now on sab, as i sure you know burglars will want to break into a house where they are less likely to be seen, in my case this would almost certainly be the back of the property, so with that being said is it better in my case to have an ear piercing loud sounder at the back (sab) and have the front sounder changed to scb so it's just loud enough to attract nearby neighbours which my house is surrounded by? Is this acceptable? Or is it best practice to leave as it is? How do you guys generally set it up? Would you do something different? Maybe put both sounders on scb and go for a very loud internal sounder something like an elmdene int400/402? Thanks Quote Link to comment Share on other sites More sharing options...

CR Alarms Posted April 20, 2020 Author Share Posted April 20, 2020 Hi all, sorry to pester you once again, i managed to get hold of an elmdene elm300 it's an scb Internal sounder which will draw at the most 80ma charging current from the panel, can i safely add this to the system? I know from the scantronic 9600 manual it can supply 1250ma at 20 degrees, my total current in alarm is 840ma, so it will be 920ma worst case if the elm300 sounder it taking full charging current. One thing that has always baffled me is the 9600 manual does not say what the bell hold off terminals (0v and 12) are capable of supplying? Am i correct in thinking that the total load is 1250ma but you have to factor everything else on the system to determine how much you can draw from it? The load from both external Sounders take 420-430ma from the hold off circuit. Given i want to keep the total load under 1amp, am i correct in thinking the max that can be drawn from the bell hold off circuit will be around 580ma? How i worked this out was calculating the keypads panel, detectors and speaker, the total draw from these (speaker sounding obviously) is 421ma, taking this away from the power supply output i could potentially draw 830ma from the bell hold off circuit, obviously i want to stay under an 1amp so i will knock off 250ma, so in which case the max remaining current i can draw from the bell circuit is 580ma. Is this how the loading works for this panel? Or does the bell have its own polyfuse? If so surely the manual would mention this but it does not, so i can only think the 12v on this system ( aux ,bell hold off, ect) is all commoned together and the limit is 1250ma and you build the system ensuring you stay under this figure, for the being sensible i will be staying below 1 amp. Does this sound correct? Thanks Hope this makes sense, Here is the relevant info from the manual Quote Link to comment Share on other sites More sharing options...
