I have a very old but reliable FBII XL 4600 system that uses white wires with 4 wires inside( red, black, yellow and green). Could you please help me identify this cable so I can buy more to wire a new zone? Thanks in advance. I'm really enjoying your videos.

Hi. If you have the kind with the siren/alarm stays on for 30 sec after the alarm has been sounded, and can open one up to see...How does that work ? Does it have a tiny clock/timer that will engage the magnet after 30 sec ? thx. just curious
