aissecur Posted June 11, 2018 Share Posted June 11, 2018 The panel contains NVM - non volatile memory, this should retain all your codes / settings Quote Link to comment Share on other sites More sharing options...
karl taylor Posted June 11, 2018 Author Share Posted June 11, 2018 Thanks for that information. Strange this. Have just come home now off shift and i have noticed that the key pad is illumanted and saying unset. It was off yesterday. Very odd. However it is saying 2nd january 7.31 time. I have tried putting my security code in in but it doesnt respond. Would i be correct in assuming it will not fully work until i replace the one amp fuse that has blown Then i will just have to change the time and date . Dont know why its saying this date etc or why it has now come back to partial life as was dead yesterday.... Please see picture of what fuse is blown. Its the middle one. Was thinking that the bottom might have blown as thought that looks after key pad but it was ok upon removal and checking.. Quote Link to comment Share on other sites More sharing options...
aissecur Posted June 12, 2018 Share Posted June 12, 2018 I would change your fuse, there is a possibility that if your code doesn't work the panel may of defaulted back to the default code (quite rare for this to happen but not unknown) By the looks of your panel it is a CPX Quote Link to comment Share on other sites More sharing options...
karl taylor Posted June 12, 2018 Author Share Posted June 12, 2018 Thanks for that information. As soon as i get the fuses i one in and try it. Hopefully it wont have defaulted to another code as i wouldnt know what that would be. I am just assuming the bottom fuse in the picture is the fuse for the illumanation of the key pad? As it says on the board key.....? And the one that has blown controls the door and pir sensors and key pad???? Quote Link to comment Share on other sites More sharing options...
karl taylor Posted June 12, 2018 Author Share Posted June 12, 2018 hi all . Any ideas on this. have isolated the pir . seperatly taped up red and black wires to it. and have joined tamper wires together and taped up and zone wires together and taped up. key pad is working in engineer mode as got the code. issue now is it is coming up with a internal alarm saying: bell box tamper fault. Then saying zex 8 tamper check !!! the bell box is not flashing and no lights . am i correct in assuming it because this 1amp fuse is blown in the panel ? the second fuse in the panel i am waiting to get. what else can it be? does this fuse control the pir. Door sensors and bell box ? Any one know?? Quote Link to comment Share on other sites More sharing options...
karl taylor Posted June 12, 2018 Author Share Posted June 12, 2018 If any one who has had experience of this problem please reply. What i believe has happened is when the alarm was in engineer mode and i touched the red wire of the pir to some thing when i was taking the wires back out of the pr it blew the fuse which is for the power supply to the wired and the wirelss sensors and the pr and door contacts. In doing so it set the bell box off for 30 minutes. The key pad went dead. Today the key pad is working so am assuming its getting its power on a battery back up. Engineer code works So upon entering the engineer code the bell box has stopped flashing and has no lights so assuming before it was on it battery back up. The key pad is saying bell box tamper and zex 8 tamper I can only assume until i get a new fuse that this fuse protects the controls of the power supply to the above parts of the alarm ?? Any one know? When i decorate another room in the future is it always best to take this fuse out or will it set the outside siren off??

aissecur Posted June 13, 2018 Share Posted June 13, 2018 (edited) wait for your fuse to come, down power your panel - ensure no cables are shorting out reconnect your PIR re-fit blown fuse (check all other fuses with a multimeter & if blown change - ensure you replace with correct size) Power back up, silence alarm & reset Edited June 13, 2018 by aissecur Quote Link to comment Share on other sites More sharing options...
aissecur Posted June 13, 2018 Share Posted June 13, 2018 If you decorate in future , a suggestion would be to remove a pir (and you feel competent enough) you could drop the cables out of the 12v AUX terminal in the control panel, carry out the works, then when complete reconnect the 12v+ Quote Link to comment Share on other sites More sharing options...
