The personal wireless remote can arm or disarm the base unit. It has a key chain hole which allows it to connect to your key chain if you wish. There is also a panic button that sends the base unit into a panic mode upon a single button touch.
This wireless remote enables a quick arm or disarm of the home base unit. It is extremely easy to use as there are only 2 buttons on it.
You may use an unlimited number of any combination of add-ons. However, the base unit (SSC-ALM1) is REQUIRED for any of the add-ons to function.
