INTRODUCTION
The WK820 and RC840 are one-way wireless keypads primarily designed as additional arming stations, including three arming keys that enable Full, Part or Perimeter arming modes. Pressing the Full and Perimeter buttons simultaneously generates an SOS panic alarm. Additionally, the keypad may be used to control Home Automation modules.
The WK820 also includes an additional Cancel key ⊗ that clears the keypad in the event that a key is pressed by mistake while entering a code, for example. This key causes the keypad to disregard what was previously entered enabling the user to start again.
