The new family of addressed sirens of the SOUND line extends the range of devices addressed on loops with ONEPROTOCOLL protocol.

Simple to install, thanks to the extractable terminal board and the deep base, easy to program using dip switches and jumpers, they comply with EN54-3 and EN54-17 and in the case of SOUND 110 also with EN54-23.

Each siren can be addressed manually, by ONEPROGRAMMER programmer or by fire detection control unit with ONEPRO- TOCOLL protocol or with auto addressing by fire detection control unit with ONEPROTOCOLL protocol.

All sirens are equipped with a short-circuit isolator conforming to the EN54-17 standard.
