By using an InfraRed relay (IR2ML) a person can activate a door opener using any InfraRed transmitter. On solid doors rather than glass doors a second receiver, called a detector is required on the outside.
The IR Relay detects when a particular key is pressed and triggers the door to open. The IR1SP transmitter is an ideal transmitter to use when outdoors. It is worn like a pendant or can be attached to a key ring and has one button.
IR Relays can control many things apart from door openers including lifts, alarm systems and much more. Contact us with details of your requirements.
