An electrical door opener can be controlled by an electronic
code lock or a transponder. However, this always requires
running a cable, installing a keyboard (tamper-proof) or fitting
a concealed coil. All of this can be avoided by using a
radio remote control of the type used for cars. The receiver
can be fitted directly to the electrical door opener. Various
types of aftermarket sets for controlling a centralised locking
system are available in accessories shops. They cost
around 50 (£ 30), including a handheld transmitter.
Connecting the radio module is child’s play. Instead of the
servomotor, a 12-V relay with normally-open or changeover
contacts is connected to close the circuit to the door
opener. The supply voltage for the radio module can be
taken from the door opener. Models
