How do I wire a door strike or magnetic lock to my receiver?

All Linear receivers that use "dry contact" outputs do not supply voltage from the relays. This means that the receiver does not supply the voltage for the door strike or magnetic lock. You will need a power supply that supplies the correct voltage and sufficient current to operate the door strike or magnetic lock. You can use a single power supply for both the receiver and the door strike or magnetic lock if both the receiver and the lock use the same voltage and the power supply provides sufficient current to operate both devices.You will switch one leg of the power supply for the door strike or magnetic lock through the relay on the receiver.

The wiring would be connected as follows:

  1. Wire one side of the power supply to the common on the receiver relay.
  2. Wire one side of the door strike to the N/O (normally open) contact on the receiver relay. If you are using a magnetic lock, then wire one side of the magnetic lock to the N/C (normally closed) contact on the receiver relay.
  3. Wire the other side of the door strike or magnetic lock to the other side of the power supply.
NOTE: Make sure that the current draw of the door strike or magnetic lock does not exceed the current rating of the relay in the receiver.
