The International Console with Speaker / Microphone is equivalent to the standard Omni Console with Speaker/Microphone except that it has no silk screen on the front and features universally recognized icons which makes it appropriate for all languages and regions. The traditional looking security keypad is designed for use with an OmniPro II, Omni IIe or Omni LTe security automation system. All control, security and programming functions can be accomplished using a Omni Console. A two-colour LED offers status at a glance: red for security armed, green when disarmed. This Omni Console has a speaker and microphone. For the speaker and microphone to work you must install a Two-Way Voice Module (Part Number 10A11-1) in your Omni family home control system. The microphone may be used to listen inside your home while on-site or remotely via telephone. The speaker may be used to broadcast messages, based upon system programming or be used to communicate with someone inside the house. With an OmniPro II automation system, you can even leave a message for someone via the phone interface that is immediately and automatically announced when someone disarms its security system. Omni Console has large buttons, a cool blue backlight and a thin profile. The LCD display features 48 character capacity with menu operation, selectable key click, beeper functions and viewing angle adjustments. The face is silkscreened with the menu options printed on the console face.
