Designed to meet all the harsh operational requirements of any fleets equipment, ECCO 600 Series alarms feature a reverse-mounted speaker design and reinforced nylon housing providing unrivaled durability. These alarms are so robust that an ECCOLIFE™ warranty covering the alarm for the life of the vehicle is offered on all models. 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.
