Security System EN1550
The audible alarm (siren) is not working. The other functions were working. We are looking for a detailed schematic for this system. Can anyone assist?

The odds are that the actual siren has failed. Your system is most likely a DSC PC1550 that's been rebranded (a common thing).
Simple test. If you have a multimeter, put the system in alarm and test the terminals labled "Bell", it should have 12VDC when in alarm. If there is no voltage, there is a 5amp - 5X15mm fuse on the top edge of the circuit board for the bell circuit.
