Fantoma Posted September 1, 2017 Share Posted September 1, 2017 (edited) I am in the process of replacing my external Bellbox which is connected to a Securit 700L Control panel, the system was installed when the property was built around 1996-7, there is no name on the Bellbox except the flaking writing with the Installers name & phone number. Amazingly I still have the original Engineer instructions (with all codes) and it all still works after having replaced the Battery in the control panel, I then decided to check the Battery in the Bellbox thinking that was also due to be replaced, on removing the Bellbox cover I could see that one of the Battery wires was not even connected and just dangling loose and I suppose it was never connected during installation but has never caused a problem. So after a bit of research I purchased a Pyronix Deltabelle plus Bellbox and I need some help with the wiring, I have cross referenced some of the wires but not all of them, bellow is what I have with some images of all components to help you help me. This is my current set-up Securit 700L Control Panel External Bellbox And this is the Installation diagram for the Pyronix Deltabell Plus My understanding from this is as follows, could you please confirm and fill in the gaps. Deltabell Bellbox Securit 700L Control Panel T (1st T) = Tamper Return (Yellow) R- (Bell Tamper return) T(2nd T) = Tamper Negative feed applied and - (Bell Hold Off Neg supply & Bell Tamper) linked to Negative in Bellbox (Black)?? Eng Hold = ???? ??????????? STB = Strobe Trigger (Green) ST- (Strobe switched Negative trigger) Bell = Bell Trigger (Blue) S- (Bell switched Negative trigger) 12v + = Positive Hold Off (White) + (Bell Hold Off/ Strobe Positive Supply) 12v - = Negative Hold Off (Black) - (Bell Hold Off Neg supply & Bell Tamper) ?????????????? (RED) + (Bell Hold Off/ Strobe Positive Supply) On my existing Bellbox I have a terminal E looped with a Black wire to A- which is connected to Bell Hold Off Neg supply & Bell Tamper in the Control panel, is this E the old style Engineers Hold Off? The Deltabell has Eng Hold terminal, where should I connect this to in the Control panel? Any help at all would be appreciated, thanks in advance. If you need any more info or images please let me know. Thanks. Edited September 1, 2017 by Fantoma Image move down. Link to comment Share on other sites More sharing options...
al-yeti Posted September 1, 2017 Share Posted September 1, 2017 Might not be what your looking for but Why are you not scrapping the panel aswell? 1 Link to comment Share on other sites More sharing options...
al-yeti Posted September 1, 2017 Share Posted September 1, 2017 Apart from that ignore engineer hold you could connect it if you want at the bell side and leave it disconnected at panel end Link to comment Share on other sites More sharing options...
sixwheeledbeast Posted September 1, 2017 Share Posted September 1, 2017 What's wrong with the panel if it works? Stick a new NiCd pack in the old bell job done, if the bell is operational. As for fitting the new, you seem to have worked it out, red and white are connected to the same place so the same thing. Engineer hold off wasn't really around when the 700L was made, so do with it what you want. If your not sure, try wiring it up on a short wire adj panel before messing about up a ladder all day.

Your right plenty spares on eBay , especially keypads, so carry on like contracts, never upgrade and never move with the times Link to comment Share on other sites More sharing options...
sixwheeledbeast Posted September 1, 2017 Share Posted September 1, 2017 It's an alarm! What's to get with the times, as long as it's serviced, is functional and suits the customers needs, I don't see a problem. Link to comment Share on other sites More sharing options...

Thanks al-yeti, I may well change the panel at a later date for a more modern system (one step at a time). Link to comment Share on other sites More sharing options...

I might try and get the ladders out shortly and I'll let you know. Thanks a lot for the advice. Link to comment Share on other sites More sharing options...

Thanks, trying it on a short wire is a great idea. Link to comment Share on other sites More sharing options...
norman Posted September 1, 2017 Share Posted September 1, 2017 Nothing wrong with the 700l, and if it's not broke... Nothing is foolproof to a sufficiently talented fool. Link to comment Share on other sites More sharing options...

Absolutly, that old adage is spot on, problem is as human beings sometimes we can't help ourselves messing with things that aint broke. Link to comment Share on other sites More sharing options...
Fantoma Posted September 1, 2017 Author Share Posted September 1, 2017 Success is a slow process, problem is I'm sometimes a bit too slow and I suppose on that basis I should be very successful but I'm not. My point is I took my time with this little project and studied it to understand, then I came here to the professionals seeking advice and final approval, of course you did just that so acting on your confirmation I got the ladders out this afternoon and replaced the old Bellbox with the new Deltabell, reconnected the Battery and the powers supply at the control panel and jobs a guddun as they say, tested it and everything works perfectly with no problems at all. BTW I checked the old Bellbox and it was definitely dead but no fault showing. I would like to thank all of you for your quick response and support in helping me out, I only submitted my post late this morning and the same afternoon jobs completed. I am extremely grateful, oh and the banter's not bad either. Now I need to work out how to close the post or mark it as completed (in the words of Homer Simpson.....Doh.... where's the 'Any Key') Thanks again Guys.
