Push Button Transmitter for the DA50L-A. The push button adds a commercial grade "doorbell" function to the DA50L Entrance Alert. There are many applications for this product.
Real World Commercial Applications:
One customer in a retail store has one mounted under the counter. When the lines grow and the clerk gets overwhelmed, he presses the button to alert someone in the back to come out and help.
We also have a walk in clinic who uses this in conjunction with an DA50L-A mounted over the door to alert the staff when patients come in the office. They also have mounted the push button mounted to the receptionist desk so customer can push the button if they need a staff member.
