Guest derrick Posted October 11, 2004 Share Posted October 11, 2004 Hi , Can anyone help A fault has appeared "out of blue" with my alarm, if i try to enter the code to set... the alarm goes off ..... I can turn the sounder off by just entering the first digit of the 4 no code, then hit reset. Can i test the keypad in any way ? (continuity test etc?) Any help would be much appreciated.

FASTCAR Posted October 11, 2004 Share Posted October 11, 2004 Hi , what else is displayed , DAY or TAMPER etc , what is on the 2 digit led display?. Has it had a new battery in the last 5 years?. Link to comment Share on other sites More sharing options...

FASTCAR Posted October 11, 2004 Share Posted October 11, 2004 Firstly , be aware that there is 240v inside panel , you could try removing the fuse from the spur , then remove the battery spade terminal.Then replace the mains fuse and hope that the panel fires up.I would check/replace the battery.There is a service guide on this site , or get a local installer to come and give it a service / check over.

This though doesn't tell you absolutely that fuse is ok. Check so that measure across battery minus and fuse. If both ends of fuse gives you the same result than when measuring across the battery + and - it is ok. There MIGHT (depending of the panel) be a diode between the battery and fuse so difference can be -0,3 to -0,7 VDC. If 11.2VDC @ battery --> chance it regardless if it causes the fault or not (should be approximately 13.8VDC). It is in end of life. Link to comment Share on other sites More sharing options...

Guest Posted October 11, 2004 Share Posted October 11, 2004 i would guess that if the battery voltage is even lower than in control box it is in end of life also... Link to comment Share on other sites More sharing options...
bellman Posted October 11, 2004 Share Posted October 11, 2004 Battery has probably cooked itself, It should be replaced after 5 years as a matter of course. you should get at least 12.8 volts out of the battery, i'd replace the battery and replace the fuse, do be careful as there is LETHAL voltages inside the panel. check to make sure you have at least 13vdc at the batt leads in the panel before connecting the new battery.

bellman Posted October 11, 2004 Share Posted October 11, 2004 If you get no voltage between batt ov terminal and either end of the fuse holder that would be indicitave of the charging cct being fried, Regards Bellman Service Engineer and all round nice bloke ) The views above are mine and NOT those of my employer.
