This module is used to connect a remote firefighter telephone to a centralized telephone console. A ringing sound is provided at each off-hook handset until it is connected to the console. Wiring to individual telephone jacks and handsets is supervised, and status is reported to the panel as NORMAL, TROUBLE, or TELEPHONE. This module has two pairs of output termination points available for fault-tolerant wiring, and includes a panel-controlled LED indicator.
Firephone Control Modules are intended for use in intelligent, two-wire systems, where the individual address of each module is selected using the built-in rotary switches
