How does the 3GL mount inside the Lynx panels?
When you purchase a Honeywell 3GL cellular communicator you'll get a connector chip in the box along with the communicator. This connector chip is what is used to mount the 3GL in the Lynx Touch panels.
Iside the Lynx Touch panels there is a receptacle that the connector chip fits in. There is also the same kind of receptacle on the 3GL communicator. The connector chip plugs into each of these receptacles connecting the two.
