martin691 Posted July 9, 2011 Share Posted July 9, 2011 Hi, I have a Scantronic 9651 hardwired control unit and a 9943 keypad. I have the following zones Zone 1: Fire (FR) Zone 2: Normal Alarm (NA) Zone 3: Normal Alarm (NA) Zone 4: Normal Alarm (NA) Zone 5-8: Not Used (NU) I am usings CC + Com A/T as a zone configuration. When I go into installer mode, and then press 99 and tick, the display shows as expected: 99:Checking bus 99 Exit Eng? I then press the tick, and it shows: 99:Checking Sys Shortly after this it flicks through the following messages: Tamper Zone 01 Tamper Zone 02 Tamper Zone 03 Tamper Zone 04 I checked the resistance between the 2 COM A/T connectors, and it was about 1kOhm. I thought maybe this value is too high, so I connected a wire direct between the 2 connectors, so that it gave a zero resistance value, but when I then did the whole procedure above and it ran through the checks, it said the same thing. Surely by shorting between the 2 COM A/T connectors it shouldn't register a tamper? In the attached photo, you can see that there is a blue and white wire going into the COM A/T connectors, and then I put a black wire accross the 2 to test the Anti Tamper problem. Thanks in advance for any help. Martin Link to comment Share on other sites More sharing options...
miaren Posted July 9, 2011 Share Posted July 9, 2011 It may be the way the panel has its zones programmed. Check the manual for the correct zone setup. Link to comment Share on other sites More sharing options...
martin691 Posted July 9, 2011 Author Share Posted July 9, 2011 I gave details about how I configured the zones, but just to give more info: Zone 1: Fire (FR) abcd Zone 2: Normal Alarm (NA) ab Zone 3: Normal Alarm (NA) ab Zone 4: Normal Alarm (NA) a Zone 5-8: Not Used (NU) I don't know if this answered it, and if not, I don't know what you mean. Thanks Martin Link to comment Share on other sites More sharing options...
martin691 Posted July 9, 2011 Author Share Posted July 9, 2011 I also changed all zones to NU (Not Used), which stopped the message. I then set zone 1 back to FR and it came back with the message: Tamper Zone 01 I then change Zone 4 to NA (Normal Alarm), and made all others, and it came back with: Tamper Zone 04 I would guess no matter which zones are NU, the tamper circuit will remain the same regardless. Thanks. Link to comment Share on other sites More sharing options...
reidy Posted July 9, 2011 Share Posted July 9, 2011 I think miaran was refering to zone wiring as in is the panel setup as FSL or CC Hey Ho, Lets Go Link to comment Share on other sites More sharing options...
martin691 Posted July 10, 2011 Author Share Posted July 10, 2011 When I press 21 and a tick in installer mode, I get the following: 21: CC+ComA/T I wired it as CC, so have not used resistors, and the tamper loop has very little load over it, so in my opinion should not be showing tampered. Thanks. Link to comment Share on other sites More sharing options...
Oxford Posted July 10, 2011 Share Posted July 10, 2011 Take the tamper pair out and put a hard link across the a/t on the board and see what happens. Then proceed to meter out each tamper circuit individually. I take it the tampers are in series and not parallel? Link to comment Share on other sites More sharing options...
miaren Posted July 10, 2011 Share Posted July 10, 2011 Worth putting the 2k2 resistors directly across 1 or 2 zones. Then exit programming. If the panel still thinks its FSL, those zones should dissapear. Link to comment Share on other sites More sharing options...

Then proceed to meter out each tamper circuit individually. I take it the tampers are in series and not parallel? Unless I misunderstand this, I put a black wire going accross the a/t as you can see in the photo. The tampers are in series. The current resistance accross the tamper contacts is zero. With and without the direct wire, the result is the same. Worth putting the 2k2 resistors directly across 1 or 2 zones. Then exit programming. If the panel still thinks its FSL, those zones should dissapear. Do you mean putting the 2k2 resistors instead of the yellow and green wires that you can see in the photo? Therefore I will not be touching the tamper loop. I will try that now. I don't think the panel thinks its FSL, because pressing 21 and a tick comes back with CC+ComA/T. I changed it to FSL which had the same Tamper messages, and then changed it back again, and still had Tamper messages. Link to comment Share on other sites More sharing options...
