ABSTRACT:
A remote alarm apparatus is described. A transmitter is communicatively coupled to a primary communications device. The transmitter broadcasts a notification signal in response to a primary communications device alert. The notification signal is a phase modulated, radio frequency signal. A remote alarm indicator provides remote notification of the primary communications device alert. The remote alarm indicator includes a radio frequency receiver for receiving the notification signal, an alarm indicator, a decoder, a battery, and a switch. The decoder provides a signal to the alarm indicator corresponding to whether the notification signal has been received by the radio frequency receiver. The switch is coupled to permit deactivation of the alarm indicator. The battery provides power to the radio frequency receiver, the alarm indicator, and the decoder.
