MWRTA02A Transmitter with Alarm and Receiver
The Miller Edge Model MWTA02 gate and door edge transmitter with matching receiver is designed to provide obstacle sensing protection for a variety of motorized gates and doors. It is easily mounted and wired to the gate or door edge sensor. When the SensingEdge comes into contact with an obstruction, a closed circuit signal is created and is sent to the transmitter. The transmitter relays the information to the receiver and the receiver passes the message along to the operator motor. The gate or door stops movement instantaneously and will then reverse the direction of travel. The Model MWTA02 is available with an Audible Alarm feature that activates when the battery has only 25% of its life remaining, indicating the battery should be replaced. The alarm sounds for 5 to 10 seconds at 1 to 2 minute intervals.
