Our wireless driveway alarm kits are perfect for installations that need to monitor vehicle traffic up to 2500' away. The Milton driveway signal hose and black transmitter box can be set up at the end of a very long driveway and monitored with a wireless chime. The driveway chime produces a soft ring and has a built-in volume control. The chime kit plugs into an ordinary electrical outlet, and the end-of-driveway unit operates off of a 9-volt transistor battery. The complete wireless driveway alert kit includes all of the pieces necessary to set up your driveway alarm system. The Milton driveway alert system includes one wireless electronic driveway chime alarm, one end-of-driveway transmitter box, one driveway signal hose, and one rubber end cap. This wireless chime kit works perfectly for customers who need a wireless signal between the driveway hose and the receiver chime and for long-distance application
