Chapter 1 Product Overview
Matching Digital FD&A Panel, VG-6762 Digital Fire Repeater is designed to monitor and indicate fire
alarm messages. The fire repeater has a TFT display, LEDs for indicating messages of critical conditions,
which can display directly fire and fault messages from digital control panels.
VG-6762 Digital Fire repeater communicates with the Digital FD&A Panel through loop line. It can be
mixed with detectors and modules to program the addressable points ranging from 0 to 255. The local
address is set on the fire repeater. Each fire repeater can be set to four display range. Addresses of the
detectors can be not only individual, but also continuous. The repeater panel can display conditions of
detectors whose addresses are included in the preset range. Those conditions of detectors outside the
range are not displayed on the repeater panel.
Each fire repeater can display maximum 100 fire messages or 100 fault messages. The messages
exceed 100 are not displayed.
VG-6762 Digital Fire Repeater has functional keys on its own, which can be used to scan received fire
alarm and fault messages. The Fire repeater can also be communicated and controlled by the intelligent
fire alarm control panel. When the intelligent fire alarm control panel is silenced and is reset, the
messages can be sent to the fire repeater to make it silence and reset, so that the system can be
centralize-controlled.
