Krown KA300TX Wireless Transmitter

To use the KA300TX transmitter with the KA300 Alarm Monitor Receiver, attach the transmitter to the siren of an existing alarm unit, such as a smoke detector or carbon monoxide detector using a hook & loop type fastener, such as VELCROŽ brand fasteners. When the transmitter is activated, it will signal the alarm monitor receiver with the corresponding alert (smoke detector, carbon monoxide detector, weather alert). To use this transmitter with a Weather Alert system, see the WR300TX Weather Alert Transmitter. Not for use with the Midland WR300 Weather Alert Radio.
