 ECCO Smart Alarms constantly measure ambient noise and adjusting their sound level, creating a volume that is safe without being annoying or contributing to noise pollution. Smart Alarms eliminate the need for constant manual adjustment and help prevent intentional alarm disconnection. In addition this Multi-Frequency model operates by emitting sound at multiple frequencies within a narrow band attenuated above 4000Hz so that the sound is more directional and perceived to dissipate more quickly than a conventional pure-tone alarm. Electronics are sealed in epoxy for protection against dust, moisture and vibration.
