External devices are connected to the roommonitor by using the 12-pin terminal cable.Connecting devices to the 12-pin terminal cable1. Cut the 12-pin terminal cable in half.R Only one of the connectors is needed.2. Strip 5 mm from the ends of the wires that will be usedto connect to the devices.R Strip only the wires that will be used.R Refer to the diagram below for information aboutwhich type of device should be connected towhich wires.3. Solder the ends of the wires coming from the deviceto the corresponding wires of the 12-pin terminalcable. Use an insulation sleeve to insulate the wires.4. Insulate any exposed wires of the 12-pin terminalcable that are unused.HGABCDEFA Connect to urgency buttonB Connect to emergency buttonC Connect to doorbellD Connect to device #4 (type is programmable)E Connect to device #5 (type is programmable)F Connect to device #6 (type is programmable)G 12-pin terminal cableH Insulation sleeve3712.
