Hi,
Going to be doing a full alarm install for a farm, now I've noticed that the the Barnes will need some form of protection, my first instinct is to use door contacts to prevent false alarms. The only problem I'm having is to find a door contact with an IP rating that will prevent corrosion or any build up of dust etc.
I was thinking I could maybe find some sort of cover to make a cheaper door contact Ip rated, or apply a silicone sealant around it?
Anybody got any ideas?
Matt
