lancepar Posted April 30, 2020 Share Posted April 30, 2020 Hi, The management want me to start a new thread on this old system, but no help as to where to start it, so If in wrong place stick it where it should be. Question. System works as it did when I installed it around 1990 but the outside bell don't ring anymore. I could replace the whole lot but why? Before I have a look inside the bell box can anybody remember what was inside? I'll leave it there at the moment and see what developes.

PeterJames Posted April 30, 2020 Share Posted April 30, 2020 Any external sounder will do, the Bentley is quite old so before replacing the external sounder I would check that its not a fault with the panel bell output Quote Link to comment Share on other sites More sharing options...
james.wilson Posted April 30, 2020 Share Posted April 30, 2020 as above it could be externl sounder. That age it probably isnt an SAB so could be sounder failure, cable failure, panel failure etc etc Quote securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.

sixwheeledbeast Posted April 30, 2020 Share Posted April 30, 2020 Pretty sure they are SCB's on that age Bentley. Maybe even positive trigger? I would be checking the panel and it's outputs respond correctly to an alarm activation with a meter before even considering the ladders.
