GENERAL System Sensor’s Multi-Alert™ sounders and sounder/ strobes are uniquely suited to provide primary or secondary signaling for fire and security applications. Sounders — System Sensor’s Multi-Alert™ Sounder (MA) and combination Sounder/Strobe (MA/SS), and Signal Strobe (SS) are UL listed for primary or secondary signaling in life safety systems.
The MA Series and MASS Series provide eight different warning tones which can be selected during installation by arranging clips on tabs (see MA Sounder Tone Selection diagram). These clips can be reconfigured in the field, allowing the user to change the warning sound at any time after installation.
The MultiAlert mounts directly to 4" (101.6 mm) square backboxes. Optional mounting plates are available for either flush or semi-flush installations. Flush installations require a 2-3/4" (69.85 mm) deep backbox (model BB-D).
The UL 464 compliant sounder has a low current consumption and is listed for 12 and 24 VDC and full wave rectified unfiltered operation. Model MA12/24D is suitable for outdoor applications when installed in the optional System Sensor WBB Weatherproof Back Box.
In Canada, a rigid steel conduit must be used when installing the WBB Weatherproof Back Box. Strobes — The UL 1638 compliant SS Series signal strobe is an electronic visible warning signal that flashes approximately once every 1.5 seconds.
Available in either a 1.5 cd or 15 cd light intensity at 24 VDC or 15 cd at 12 VDC, the strobe light uses an extremely reliable xenon flash tube with low current requirements. The electronic circuit is enclosed within the durable polycarbonate lens.
