• \n1 flat system – 8 wire<\/li>\n
• 2-8 flat system – 12 wire<\/li>\n
• A 12 wire cable is the largest recommended size cable to be used for the loop-in method as the ringing wire connections have to be made in each unit. Whichever method of wiring is used the cable should be broken through a junction box at the front entrance and the lock release cable connected at the junction box behind the secure door.\n<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"
