Scantronic 9651 Internal Sounder when Unset

[Dashnine]

Hi all,

 

I've recently bought the house but only got the user code off the previous owner.  Have had a new kitchen installed but needed to move the (second) keypad by an inch, in doing so set off the tamper on the keypad.  I did a user reset but keypads showed Call Installer.  As I have no Engineer code, I reset all the codes with the first level reset (I think also mistakenly have reset everything to default).  Now in the situation when the system powers up the internal sounder is permanently on when unset, but when the system is set - it stops, restarting when I unset the system.

 

I've set up the sensors again (there are 4, all PIR - one FE, others NU), but for the life of me can't see in the installation manual or online why the internal sounder is going off when the system is unset!  Battery is OK, runs system when mains is disconnected.

 

Any ideas please?

 

Thanks!

That should be one FE, 3 NA and the remaining 4 set NU.

You've defaulted everything and whatever is making a noise is now not programmed correctly.

Check what's wired in and how it's programmed.

Thanks but I pretty much have done so, I can see the wiring for the 4 sensors, 01-04 and while system works OK when set it's just setting the internal sounder off when unset.  Nothing in the log, other than Installer logging in/out, Sets / unsets etc.  

 

Can't see anything in the installation manual as a default or otherwise that would trigger it to do so, or how to set it not to do so.

Check how the internal sounder is wired ? What connections is it going to?

I assume.leypad.jist shows model and date time with no errors? When unset and sounder activating

Excuse my ignorance, but how would that make a difference when nothings changed on the wiring, it’s exactly as it was?  Does the system have to be coded differently for having (or not having) an internal sounder?

 

Yes, keypad just shows date and time with 9651 underneath when unset and sounding.

All inputs and outputs are programmable. If you cleared the programming then the defaults may not be compatible with the system design OOTB.

Yes it was a long shot I was thinking maybe internal siren on an output changed from something

Agreed bet it's a horrible sound bomb type thing connected to an output programmed as open closed rather than bell

This is the block for the outputs, I assume some are the internal, others the external sounder.

 

OP1, OP2, OP3 and TR left to right.
