Detnov MAD-472 sounder base | addressable | 80 dB | EN 54-3

The MAD-472 is a sounder base for the Detnov addressable system, for places that need both a detector and a sounder at the same point – it shortens installation time.

Sound level 80 dB(A) at 1 m. Up to 30 sounders on a 1 km loop and up to 15 on a 2 km loop (check with Detnov's system calculator). Indoor use, IP21C; certified to EN 54-3 (0370-CPR-2665).
