The GST-FT8WN is an 8-zone fire telephone panel that provides 2-way voice communication between a central control center and up to 10 communication points on each zone, such as fire telephones, speaker handsets, or jack sockets. It allows single calls to individual zones or group calls to multiple zones simultaneously. The panel is wall-mounted and wired radially to the various communication points. Regular testing of the system is recommended to ensure proper operation in an emergency.
