The Smart Alarm^® from ECCO was the world’s first self-adjusting back-up alarm, constantly measuring 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. Compact size and universal mounting bracket maximizes location options, self grounding with stud terminal connections, sealed in epoxy for protection against dust, moisture, and vibration.
