Stoatgobbler Posted March 27, 2009 Share Posted March 27, 2009 Hi there, I've got a Scantronic 9800 to which I've fitted two extension speakers (CQR Mach 1 16ohm). The Scantronic manual states that two speakers can be fitted, I've connected them in series (giving a 32ohm load). They work fine but......I can't adjust their volume to lower the entry / exit tone, I've turned the potentiometer on the control pcb to both extremes and it seems to make no difference. Any advice please? Stoaty Link to comment Share on other sites More sharing options...

lawandorder Posted March 27, 2009 Share Posted March 27, 2009 Connect them in parrallel That will make them louder! I'm pretty sure that the volume control only affects the kepad sounder volume not the entry exit sounder. Link to comment Share on other sites More sharing options...
antinode Posted March 27, 2009 Share Posted March 27, 2009 For a start, none of the 9800's I have worked on have a volume pot. What you have probably adjusted is a factory set potentiometer (usually to do with the voltage regulator circuit) that is not supposed to be adjusted once it's been set at the factory, end user or service engineer alike! Also, the speaker on the 9800 will only signal alarm (tamper, alarm, fire, fail to set) and chime tones, not entry exit tones.

Wasn't this query about the 2 CQR extension speakers and not the 9800 one?? Link to comment Share on other sites More sharing options...

Must admit I didn't think they had either but checking the manual it seems that the 9800+ does have a volume pot. I'm guessing either the OP has a 9800+ or he has indeed adjusted something else. You are also right about entry/exit tones on the 9800 only coming from the keypad but again on the + they came from the speaker as well (according to the manual). I have never actually worked on a 9800+, it came out in the face of some very stiff competition from Menvier and I used TS 900s. Wasn't this query about the 2 CQR extension speakers and not the 9800 one?? Yes but the 9800 didn't actually have a built in speaker so I think we are all talking about the extension ones.

antinode Posted March 27, 2009 Share Posted March 27, 2009 Never seen 98+, but hopefully that's what the OP has, though I get the feeling it's the standard 98 as his volume pot does'nt seem to be doing anything Wasn't this query about the 2 CQR extension speakers and not the 9800 one??
