Door Chime Model DA4D


(1) Door sensor with two “self contained” alerting melodies

The Model DA4D “Door Chime” is a wireless motion sensor with a built-in RF transmitter, that sends a wireless signal (over 200 feet through floors and walls) to a remote receiver (sounder) or multiple sounders from multiple entries or doors. The receiver(s) provide a selection of two different, volume controlled, pleasant, alerting melodies to audibly detect where your attention is required.

Another exclusive design feature, is the motion sensor “eye”, that looks directly out of the side, providing coverage directly below the entry, instead of others that cover unnecessary, valuable floor space resulting in many aggravating, redundant signals. The door sensor “eye” has a detection range of up to 25 feet and due to our high quality optical fresnel lens, can be modified to cover any desired area of coverage from a single door entry to double doors or even a warehouse roll up freight delivery bay door.
