is there a weatherproof alarm contact available out there, or sould i just use a normal contact, for an outside gate that is attached to my garage wall, in which is the main panel........ im thinking of running an alarm contact on the opening gate. and just thought there maybe a special contact available. or as i said im just going to use a standard surface door contact and a bit of sealant!. OR actually is there a remote contact available to use within a hard wired system.........ie a reciever connected to the panel and a transmitter at the contact
