I'm installing mag-locks and fire door hold-open magnets at the moment and I'm wondering if any of the cable should be fire performance cable?
As I understand it the actual cable from the PSU to the magnets (24V system) doesn't need to be as if it's damaged by fire then it just cause the doors to shut anyway.
But does the cable from the fire alarm interface to the PSU which triggers the release of all doors if the alarm goes off need to be fire performance cable? And if so does it need to be red?
In the past I've always had the interface next to the PSU so it has made no practical difference but on this one I've got multiple PSUs to link to the one interface.
