Description: Silent Knight features low-frequency sounders and sounder bases plus a unique amplifier to provide code-mandated backup power capabilities for emergency communication systems. The new line of low-frequency notification solutions includes SpectrAler^t® Advance low-frequency sounders and sounder bases. The sounders and sounder bases are designed by System Sensor to emit a 520-Hz tone, which studies have found more effective at waking building occupants, including those with mild to severe hearing loss. The expanded line includes speakers and speaker/strobes, as well as sounder bases compatible with Silent Knight smoke, heat, and fire/carbon monoxide (CO) detectors. These notification appliances provide the low-frequency output to meet current NFPA 72 standards and International Building/Fire Code.
