HT2006 Common-Talk Selective Ring Handset Intercom
For NH908A Type Systems: Wiring between handsets shall be 4-common #22AWG and 1 selective wire #22AWG, for each handset station connected on the system. For example, a system with 8- HT2006/10 handsets would require 4-common and 8-selective wires for a total of 12 wires (minimum).
See system Installation Manual: AWD016 for more complete wiring information.
For NH208TVU Systems: Use the same wiring as shown above for the NH908A systems (between handsets), and add 1-#22AWG wire for each handset push-button that will activate an electric door release, add 1-#22AWG wire for each push-button (at any entry door) that will selectively signal to one or more handsets connected to that push-button. In the illustration shown above for 8- HT2006/10 handsets, if you had an 8-button front entry panel and a door release you would add 1 door opener wire, and 8 selective call button wires, for an additional 9 wires added to the original 12, for a minimum wiring requirement of 21 wires.
See system installation manual no. AWD057 for more complete wiring information.
For NH908A and/or NH208TVU Systems: Add one more #22AWG wire for each of the other HT2006 push-buttons will be used for any other signaling purposes, such as paging, etc.
