The Merlin C840 Wireless Security Keypad allows wireless external opening of your garage door through your Merlin/Chamberlain door opener. The wireless keypad allows for secure protection, and easy permanent accessibility into your garage. The C840 comes standard with the Security+ system, and operates at a frequency of 433 MHz. This opener was designed to be used for external entrance so is completely water proof.
The Merlin C840 is the ancestor of the newer E840M wireless keypad model, and is designed for older style garage door openers.
