Alarm went off this morning early hours, the zone was for the shed / summer house, done a test between the panel and the shed / summerhouse and there is a break in the cable between the two, don't really want to replace with 6 core alarm cable in case it happens again (Installed this run approx 6 years ago) could I use ....outdoor Cat5e Ethernet telephone/ CCTV alarm cable wetherproof..... that is selling on ebay. Thanks.
