Hkc ext alarm fault

Munch789

Hi I’m a first time poster hopefully I can get some help. I’m having windows fitted in ten days so I started to remove the upstairs magnetic reed sensors and twist the wires together to close the loop. My alarm was setting and working fine then it went off in the middle of the night with an ext bell tamper showing on the screen. I couldn’t get the fault to clear so ended up disconnecting the battery and removing the fuse at the panel. Would it be the removal of the window sensors that would of caused this? Or is it it just coincidence? Thanks any help would be great.

It could be just a coincidence or it could be the external bell is somehow wired through some of those window sensors. To clear the fault for now remove the tamper return cable & place a 4k7 resistor across BHO & Tamper Return

Thanks for the reply. I found the issue a wire had come loose at the panel. So easy fix in the end. I never had the panel open but I was working near it so maybe I managed to dislodge the wire. Thanks again
