I. Product overview

The CST-982 fire display panel (display panel for short) 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 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.

II. Product features

ü           Each display panel is connected with a fire alarm control panel via a RS-48 bus. At most 99 display panels may be connected with each RS-485 bus.

ü           The display panels can display fire alarm messages or feedback messages only rather than fault messages, action messages or other messages. 

ü           A fire alarm control panel may be used for setting the display area of a display panel. The set display panel can display the fire alarm messages of the designated area (floor display) only. Note: See the User’s Manual of the fire alarm control panel for the setting method.

ü           It can replace a JB-FSD-981 fire display panel in a 2100 system.
