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 VELCRO® 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.
