The Multiprotocol Gateway DP500 is suitable for usage in small objects in which only a ​small number of detection points must be transmitted. The maximum number of detection ​points is 330 indicating and 200 indicating and switching. Here, a fire detector is valid as a ​detection point. Because of its small dimensions and the integrated mounting rail supports, ​this device can be easily mounted into existing housing.
