Addressable Fire Alarm System Repeater

Addressable Fire Alarm System Repeater

Introduction:

Fire alarml addressable repeat is a kind of microprocessor -controlled fire display panel developed by our company. Each fire alarm addressable repeater 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 repeterl installed. When there is a fire alarm on the floor where the repeater is installed, or the neighboring floor above or below it, the repeater  will give a  horn/strobe  alarm and display the  floor No., the room No.,  and some other position information of the fire alarm.
