I'm seeking advice about why my external sounder may be malfunctioning. Several years ago I installed a DSC Powerseries alarm panel with some zone expanders and an output expander PC5204. I opted for the PC5204 because I was concerned about the amount of amps the external sounder, internal sounder and strobes would pull when the system was in alarm. Installation was fine and the system functioned fine. We haven't had need to set the alarm for a few years but recently I decided to double check it was all working ok and noticed that the external sounder no longer was functioning correctly. The external sounder is a CQR Multibox Plus. The problem is I can't get the sounder to trigger at all except for when I remove the hold up voltage and then it is obviously using the internal battery. I assumed that the trigger wire had corroded or something so got the ladder out went up and used one of the unused wires (8 core) at the box to connect a new trigger wire - I used a tone tester on the new wire to check it worked. I noticed when I went up the ladder to remove the cover but with the Hold Off voltage still applied that the sounder went off because I obviously tripped the tamper switch - so by all accounts the multibox is functioning ok. Anyway I put everything back together - ran some tests and it was working. A few days later I decided to double check and its not working again! I decided to change the wiring at the panel end and see what happens if I wired the sounder to the DSC1864 main panel instead of the 5204 but had the same problem. Its very annoying because every time I remove the Hold Off + voltage the sounder goes off so there's nothing wrong with the actual bell bit and the strobe works and is triggered fine. Could there be a malfunction with the trigger terminal on the Multibox? Is there some quirk to sounders that some experts here could suggest. Here is my current wiring breakdown with Multibox directly on to 1864 panel: CQR Multibox ------ DSC 1864 Trig -------- Bell - STB -------- PGM2 RTN -------- Zone 7 Hold Off - ----------- AU - Hold Off + ----------- Bell + Here was my wiring which was working into the PC5204: CQR Multibox ------ PC5204 Trig -------- PGM3 STB -------- PGM2 RTN -------- Zone 7 Hold Off - ----------- BLK Hold Off + ----------- Aux+ I've attached pictures below to help illustrate and adding links to full manauls. Any help gratefully received!

Hello All I'm struggling to get my Alarm panel set up as i want it, and i think i have a gaping hole in the way i have it set up at the moment. I have Texecom Premier Elite 48 with several PIRs around the property and a magnetic door sensor on the main door. i have a key pad in the hall way, where i also have a PIR. so i have set up the zones as follows: Front door: Zone Type - Entry/Exit 1 Attribute 1 - Omittable Attribute 2 - None Halllway PIR Zone Type - Guard Access Attribute 1 - Omittable, Access, Entry/Exit 2 Attribute 2 - none The problem i have is that if the front door is tripped and the alarm is NOT deactivated, only the internal alarm is triggered and the external SAB is quiet. To ensure that the external sounder is actually working i have activated a Panic alarm and i can hear the siren from the external sounder. Ultimately this means that if someone was to force the front door open, the external sounder wouldn't go off and no one outside would know. can someone please help me diagnose what the problem could be? thanks Sups
