ECCO’s most compact and popular line of back-up alarms, the 500 Series provides a cost effective warning solution with ECCO quality and reliability. A glass-filled nylon housing with epoxy-encapsulated electronics provide exceptional durability and protection against moisture, dust and vibration.
Self Resonating Circuitry monitors the frequency of the alarm's sound output on each cycle and adjusts to the optimum frequency for prevailing conditions. This feature maintains the most effective warning signal possible for the life of the alarm by compensating for speaker aging, temperature and humidity variations, as well as the effect of dust and moisture deposits.
