Fire Display Panel
Fire Display Panel Introduction:
Fire display panel is a kind of microprocessor -controlled fire display panel developed by our company. Each display panel is connected to a fire alarm control panel produced by our company via a special RS-485 interface to process and display the data sent from the fire alarm control panel. Each floor of a building may have a firm display panel installed. When there is a fire alarm on the floor where the display panel is installed, or the neighboring floor above or below it, the display panel will give a horn/strobe alarm and display the floor No., the room No., and some other position information of the fire alarm.
