Fire fighter phone system interconnections
The ES Net Digital Controller Card supports the transmission of 2-way voice communications from Fire Fighter Phones over the ES Net network.
The Fire Fighter Phone Card (4100-1270) is used to interface the Fire Fighter Phone system to the ES Net network through the Digital Audio Controller
Card. The talk line is used for the transmission of communications between the ES Net Digital Audio Controller card and the Fire Fighter Phone Card.
Notes:
• Fire fighter phone system interconnections are not supported when you set the card in digital audio controller mode.
• An unlimited number of remote phone assemblies can be connected in a system. However, the maximum number of phones that can be activated
at the same time either locally at a node or on the entire ES Net network is 7.
