• Ensure keypad to be added is not yet powered.
• Remove keypad’s front cover.
• Electrically connect keypad to endstation.
• The keypad will display its address number i.e.
• Press 1 to 4 to change keypads address.
• Press YES to accept and a conformation bleep will be heard.
• Replace keypad cover and test keypad can control the system.

• The remote keypad also features a
panic attack function.
