The KF 240/641/742 4-buttons remote keyfob is a battery operated, wireless remote control designed for basic operation of Videofied security systems. Four buttons allow the activation or desactivation of several arming profiles (full arming and 2 special arming profiles). The arming is confirmed by a red double flash from the built-in LED. Disarming is confirmed by a green double flash. A long press on button 1 or button 2 generates a siren or silent (under duress) panic alarm. The KF keyfob uses S2View Spread Spectrum, Videofied, interactive, encrypted wireless circuitry for secure two-way communication with the control panel. Operating the system with the keyfob can normally be done from within or outside the premises and requires no access code entries.
