The Wireless keypad can easily be used to operate the Bravo wireless alarm system. It is connected wirelessly through the two–way encrypted radio communication in the 868 MHz band with an effective wireless range of 200 mtr. (open area). The proximity sensor for the backlight reduces the power consumption and increases the battery life. The signal strength can be tested remotely. The installer can easily set user codes, change the power of the backlight, disable the trouble sounds and set the sound level of the internal buzzer. The Keypad is intended for indoor use.
