## Abstract

A security system having a control unit in communication with detection devices and notification systems to provide messages. Methods for employing a control unit are also provided herein.

## Claims

### Claim 1

A communication module for a security system, the communication module comprising:
a radio interface module configured to interface with a communication port of a half-duplex radio, the radio interface module being configured to receive a voice signal from the half-duplex radio and configured to transmit an audio signal to the half-duplex radio;
a microprocessor module in communication with the radio interface module and configured to receive the voice signal from the radio interface module and configured to transmit the audio signal to the radio interface module, the microprocessor module being further configured to translate the voice signal into text data and to transmit a control signal to the radio interface module for controlling at least one control feature of the half-duplex radio; and
a signal routing module in communication with the microprocessor module and configured to receive the text data from the microprocessor module for transmission to a user of the security system, the signal routing module being further configured to transmit the audio signal to the microprocessor module, wherein the audio signal is derived from at least one detection device and indicates activation of the at least one detection device to a remote user through the half-duplex radio, wherein:
the microprocessor module facilitates selective operation of the half-duplex radio in either of a voice reception mode and a transmit mode; and
when the half-duplex radio receives a digital talk permit tone, the microprocessor module is configured to activate the transmit mode of the half-duplex radio and is configured to control the half-duplex radio based upon the control signal to facilitate transmission of the audio signal from the half-duplex radio to a remote half-duplex radio.

### Claim 2 (depends on 1)

The communication module of claim 1 wherein the text data comprises a text message.

### Claim 3 (depends on 1)

The communication module of claim 1 further comprising a variable voltage supply that is in electrical communication with the half-duplex radio for powering the half-duplex radio.

### Claim 4 (depends on 3)

The communication module of claim 3 wherein the variable voltage supply comprises a substantially infinitely variable voltage supply.

### Claim 5

A security system comprising:
a plurality of detection devices each configured to selectively transmit an alarm signal in response to an alarm condition; and
a control unit comprising:
a main processor module in communication with the plurality of detection devices for receiving the alarm signal from each detection device of the plurality of detection devices;
a half-duplex radio configured to operate exclusively in either one of a voice reception mode and a transmit mode, wherein, when in the voice reception mode, the half-duplex radio receives a voice signal from a remote half-duplex radio and, when in the transmit mode, the half-duplex radio transmits an outgoing audio signal to a remote half-duplex radio; and
a communication module comprising:
a radio interface module interfaced with a communication port of the half-duplex radio;
a microprocessor module in communication with the radio interface module; and
a signal routing module in communication with the microprocessor module;
wherein, when one of the detection devices detects the alarm condition:
the detection devices transmit the alarm signal to the main processor module;
the main processor module generates a control signal and the outgoing audio signal in response to the alarm signal and transmits the control signal and the outgoing audio signal to the signal routing module;
the signal routing module transmits the outgoing audio signal to the radio interface module and transmits the control signal to the microprocessor module; and
the microprocessor module determines whether the half-duplex radio has received a digital talk permit tone, and when the half-duplex radio has received the digital talk permit tone, the microprocessor module activates the transmit mode of the half-duplex radio and controls the radio interface module based upon the control signal to facilitate transmission of the outgoing audio signal through the radio interface module and from the half-duplex radio to a remote half-duplex radio; and
