When the off the shelf entry alert from the big box store retailers simply won’t due, look to the DA50L-A.  Simple to install but powerful, this product has the range you need to get the job done right!  An alert is sent to a remote receiver whenever a person passes through the Passive Infrared Sensor.  Install multiple sensors for several doors and up to 4 chime receivers to hear the alert in different locations.

Do you need Instant Notification when Motion is Detected, or when Customers enter your Office or Store?

The DA50L-A, or the Rodann TX/RX-1000A is a long range, wireless, entrance alert product that uses a PIR based transmitter and plug-in receiver.  This is our best selling, flagship product at 1800doorbell.com. This is one of the best entrance alerts we offer. The entry alarm has been used to alert store owners when a customer enters a store, alert homeowners when kids open the basement door, or notify offices and warehouses when a stock room door has been opened. The DA50L-A Wireless Door Chime Set is a high-quality passive infrared (PIR) door chime that detects infrared waves whenever something crosses its path. Because it does not use light beam projectors or reflectors, the DA50L-A is resistant to false alarms triggered by light. Works with both open or closed doors. The DA50L-A Wireless Door Chime is battery operated – no wiring required. It is perfect for both personal use in the home as well as commercial use in warehouses or other commercial settings.

Great Product

Received product and installed flawlessly according to the instructions. Sensor works very well and does not spread too wide like another type we had prior. We sell appliances and sometimes customers stand right inside the door looking at products. This beam stays very close to the door and does not keep ringing when someone is standing close to the door. Would recommend!


Works Great!

Very Satisfied

Our new doorbell allows us to know whenever customers walk through our doors.
