The 40 series back-up alarms utilize a standard 4.5” rear-lighting grommet for mounting directly into the vehicle body. Vehicle down time is reduced since the alarm can be fitted or replaced quickly and easily without the use of tools; there are no holes to drill and no bolts to tighten. Not only is the ‘in-body’ mounting method easier to install, it also ensures the warning signal is projected where it is needed, directly into the hazard zone at the rear of the vehicle. ECCO’s Smart Alarm models measure ambient noise and adjust 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.
