摘要:
A system and method for operating a security system include a device control module configured for electronic communication with a plurality of devices and a user interface coupled in electronic communication with the device control module. The user interface includes a voice memory and a first speaker. The user interface is configured to receive a first system event from the device control module identifying a first condition detected by the security system. The user interface is further configured to retrieve a voice message from the voice memory corresponding to the first system event and transmit the voice message via the first speaker.
摘要:
A differential transformer-free hybrid circuit includes a first amplifier configured to receive a first signal from a transmitter and output the first signal to a telephone loop, and a second amplifier configured to receive a second signal from the telephone loop and output the second signal to a receiver. Further, the differential transformer-free hybrid circuit also includes at least one balanced network element and a transformer-less interface configured to couple the first amplifier and the second amplifier to the telephone loop, wherein the transformer-less interface includes at least one current blocking device.

摘要:
A controller for outputting audio having a predetermined output sample rate. The controller is programmed to receive an audio signal having a first sample rate, identify the first sample rate of the audio signal, select a converter based on the identification of the first sample rate, and convert the sample rate of the received audio signal to the predetermined output sample rate.
摘要:
Property monitoring system and method of operating. Two signal lines are used to couple a master controller in series with a plurality of indicators. Each indicator has a visual display. Each visual display has a plurality of LEDs, or other type of lighting device. The master controller is configured to generate a multi-bit digital command message to be transmitted serially to the plurality of indicators over the second signal line upon receipt of an alarm condition message. Each command message has a predetermined time delay for activating each of the indicators, or a component thereof, so that all indicators activate in unison.
