The Sonora II BAAS-Sa-Me and BAASL-Sa-Me are the variants with recorded message of the Autonomous Sound or Sound and Light Alarm Blocks of the Sonora range. The Sonora II BAAS-Sa-Me and BAASL-Sa-Me are recommended for performance halls and cinemas. The BAAS-Sa-Me and BAASL-Sa-Me broadcast a general audible alarm signal in accordance with the NFS 32001 standard, followed by the recorded message, then the NFS 32001 again and a class S light (flash) signal in accordance with the NFC 48150: 2014 standard. This signal is triggered by a control order from a BAAS Celtic Pr (main) or a CMSI. A digital control loop connects all the BAAS-Sa-Me and BAASL-Sa-Me of an installation. It ensures the synchronization of the alert signals, the putting into "test" mode or "maintenance" mode of each block. The "maintenance" mode simplifies the verification of the inter-block link and authorizes the disconnection of one or more of them without triggering the general alarm signal.
