The board is designed to provide the possibility of supplying light (text or symbolic), sound alarms in fire alarm and fire extinguishing systems when working together with receiving and control devices.The display can be equipped with a backup power source - a battery, which makes it possible to generate an alarm signal after the power supply is cut off. The display can be used in hazardous areas and rooms of classes 1 and 2.
