Guest Aled Posted September 27, 2006 Share Posted September 27, 2006 if you can't mend it get the raf to pick us up, I will sort it for a decent meal & go on the machine gun It'd be great if the RAF could pick us up at the right time/place, let alone trying to get you guys out here with them! And a decent meal is probably a little beyond what's available here too!! The machine gun however.....!! Link to comment Share on other sites More sharing options...
arfur mo Posted September 27, 2006 Share Posted September 27, 2006 Several things spring to mind. Firstly make sure that there isn't a resistor fitted in the terminals of the sounder. For some odd reason some manufacturers ship internal sounders with a resistor on one terminal which makes the sounder quieter. You need the wires to connect to the wires on the sounder (obviously via the connector).Dave hi Dave, some did this to stop damaging the speaker driver high output transistor stag, as if it was not met with a low ohms path when driven, the base junctios would be destroyed. obviously, a bit flipping daft as if the cable got chopped during a inrussion or building works then it blew them. guess what happens when the client can't stop the noise? they invariably diss the speaker and 'POP' regs alan If you think education is difficult, try being stupid!!!!

Guest Aled Posted September 29, 2006 Share Posted September 29, 2006 Thank you one and all - the alarm is now fixed! It came down to a knackered speaker. The two spare that I'd tried swapping in were also u/s hence not solving the problem earlier. That's one of the big disadvantages in having a brand new team work out here every 6 months - unless everything is labelled properly, there's no way of knowing whether a shelf is of working spares or kit waiting to be back-loaded to the UK! Anyway, thanks again - this is indeed a great resource - I'll definitely be passing on this forum's details to the next team who replace us! Aled.

arfur mo Posted September 29, 2006 Share Posted September 29, 2006 hi,on the lines Lurch suggest, if you can borrow a spare known working speaker from another panel and test it at the panel with some spare wire to see if the cable run is damaged. if this is still low disconnect any wires you can and test the panel alone, you may have a short somewhwere between cables like nail through a couple of them (or where your working some shrapnel or a 303 cal ) hi all, now was i on the money - or was i on the money? ok accidentally attributed my reference to Lurch so ooops, but am i just too darned good for this forum?, you lot are lucky ro have such a king as arfur to rule over you regs alan If you think education is difficult, try being stupid!!!!
