Alarm went off middle of night scatronic 9651/9930

This is winding me up now.

Checked resistors across door contact, they were just about in spec. Went to RS components to get new ones.

Replaced resistors and replaced the original 2 core wires with two that weren't originally being used. Same problem!

I'm running out of ideas. I've linked out the tamper at the PCB, internal control box battery seems ok, and I've replaced door contact, resistors and wires.

Any other suggestions more than welcome.

For my own sanity, I've disconnected the internal sounder and the siren in the bell box, so when it triggers only the keypad rings/alarms. Could this be anything to do with it? I didn't want to attach the Sounders as they're driving me mad.

Thanks.

Is the cable a separate one or does it share it with anything else ? What do you have on that cable at the control panel end ?
 
Hi sparkymarka,

Assuming I've understood correctly...2 of the 6 core wires from the door contact go to zone 1 of the PCB and one of these wires is twisted with another wire from, what I assume is, zone 2 (the hall).

I had the hump so I did a 'restore default command' (98tick at the keypad). I've tried to reprogramme the 7 zones but now it won't let me set the alarm as it say '5 problems' (one of which seems to be zone 3 is 'active'). No idea what I've done! But it hasn't alarmed with the tamper error for the past hour.....


Assuming anybody cares, I'll keep you updated as this is driving me crazy....

If the zone is wired EOL then you need to put a 2.2k resistor across the zone in the panel not a wire link

Hi handymanjo, see attached photo.

White and green wires come from door contact (changed from blue/black from previous pic incase it was the black/blue wires playing silly buggers).

Since I messed about with resetting the system, the issue has moved from the original 'tamper error' to now just not being able to set the system and having errors with the other zones (nothing seems to come up in the 'walk test'). I'm now powering everything down and will try to reboot to see if that sorts it...

Back at work tomorrow so may have to leave any further updates to the weekend.

Thanks again.

Sounds like you have done a full default and the panel now needs to be completely 're programmed.
Should have asked questions before default panel
 
Agreed...although, i thought i was asking questions before.

Irrespective, i was hoping i had reprogrammed according to pages 26-29 of the manual but the panel isn't happy with me...not sure what i'm doing wrong...
 
Why do people mess with things they have no idea about ....defaulting the system , you have now made a single issue into a multiple issue ....best of luck
 
Thanks, sparkymarka. Really appreciate your constructive and insightful comments and knowledge of the situation.

A bolted horse and stable doors spring to mind, but let's not digress...
 
In case this helps anybody else...seemingly got there in the end. Had to reconfigure the zones and reprogramme everything (maybe more trial and error or more luck than judgement rather than anything else) but everything seems to be back to normal - no errors/alarms overnight and all the zones set and the walk test works.

Unfortunately still don't know what caused the problem in the first place....dodgy door contact? last week's heatwave? Me keying in various codes over and over again? Seems like the system needed to be cleared and re-taught - at least, that's what seems to have worked.

Thanks again for your time and constructive input.
