I General
GST8903 Intelligent Graphic Repeater Panel (hereafter called the repeater panel) is a
fire alarm display unit used in buildings and fire control center. The host
control panel in
fire control center will give an alarm in case of fire taking place in the building; at the
same time it will transmit the alarm signals to the repeater panel, which locates in fire
alarm area. The repeater panel will show the position of the alarming detector through
indicators. The personnel will be alerted and evacuated out of the fire area.
II Features
1. Small size and convenience in installation and operation.
2. Good
performance, high-reliability, and flexible configuration.
III Technical Specifications
1. Display Range: Each main board can support Max. 100 groups of
coded point and
allow parallel connection of multi-mainboard. The code supports the mode of
wildcard character.
2.
Display Capacity: Up to100 pieces of fire information can be displayed by each
mainboard.

IV Operation Principle
The repeater panel is a graphic panel developed from the microprocessor. It displays
the position of detectors and gives alarm signal at the same time. The repeater panel
connects with the fire
control panel through the communication BUS, disposes and
displays the data from the control panel. Each floor can be placed with one repeater
panel in case one fire alarm control panel
monitors couples of floors or zones.
