When a visitor–wanted or unwanted–approaches a house on foot or in a vehicle the motion-detecting sensor unit of this warning device sends a signal to the receiver indoors, which chimes an alert. The device is wireless and has a 400-foot range. It requires three C-cell batteries for the receiver and one 9-volt battery for the transmitting sensor. (Batteries are not included.) The sensor is housed in weather-resistant plastic, installs with a screw on any surface, such as a mailbox post, garage, or door.
The Alert Base Station Radio will receive alert signals from the Alert™ Transmitter and also can be used for two-way voice communications between other MURS transceivers. The BS has five channels and 38 sub channels to help you communicate with other users. The M538-BS is powered by a plug-in transformer. The BS is capable of communicating over distances of several miles.* The FCC also allows you to use MURS without a license. Although other radio services require a license, MURS is license-free.
When an alert signal is received from the MURS Alert™ transmitter, the BS will sound off with the voice of the alert signal, and will also display an alert icon as a visual cue that a signal has been received. In addition, the M538-BS is equipped with a normally open (N/O) relay output. The relay can be used to connect the base station to other existing systems such as alarm panels or doorbells. This has many different applications for small businesses, farmers, security guards or outdoorsmen. Anyone who needs to have real time monitoring and two-way voice communication will benefit from MURS.
The base station can also be used to communicate with the M538-HT hand-held radio. This allows someone in the house or shop to be in direct contact with someone out in the field. This allows a parent to keep track of the kids, or a supervisor to stay in touch with
their employees.
