The Privest Wireless Keypad is an extension module for the Privest Wireless Alarm System. Entering a PIN code, you can arm and disarm your system from any wireless control unit. Up to two control units can be integrated into the alarm system. Installed in different parts of your building, these extension modules provide extra convenience. You can arm and disarm your Privest directly from the control unit, without having to walk to the alarm control panel. Using the function keys of the module, you can send a robbery alarm, a fire alarm, and a medical emergency call. This is done by simultaneously pressing two function keys. You are not required to enter a code.
