The DA50L-A, or the Rodann TX/RX-1000A is 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 In our opinion, this is one of the best entrance alerts we offer. This 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.

Bedroom chime

We have a mentally handicapped child who tends to roam. We placed this door chime by his bedroom door. If he leaves his room, we know immediately. This works perfectly for our needs. It was, however, a little to program the sound.


Just got this item. Works perfectly !!
