Addressable alarm base A50ZSDDR

Socket for A50 addressable algorithmic detectors with EN 54-23 certified visual alarm base and EN 54-3 sounder powered directly from the loop. Two models are available: A50ZSLDR: D50 socket with base with sound and light, addressable. A50ZSDDR: D50 socket with sound base, addressable. This device requires an algorithmic-addressable detector “with SIRDR functionality” (standard detectors do not have this functionality) that will allow it to operate as a relay associated with this detector. Typical uses for the A50ZSLDR and A50ZSDDR are spaces or rooms that require integrated fire detection equipment with siren and visual alarm such as hotel rooms. The coverage of the assembly should not exceed the coverage of the fire detector with which it is installed, unless there is a reason or use that justifies it.
