The LRA-DCRX receiver features a relay that may be used to integrate and activate an external device. For example, a strobe light, 12V DC output, or other devices may be configured to trigger when the relay on the receiver activates.
Tips & Notes:
- The unit WILL NOT supply power to the external device. The external device must have a separate power supply.
- The relay ONLY works with Zone 4 on the receiver. For the relay to work, there must be a transmitter paired with Zone 4.
- The relay DOES NOT provide power.
- The relay may be set to normally open or normally closed.
- Ensure the relay is set to the "on" position./li>
- Set the duration of output to 2 seconds or 5 seconds.
In this example, we will wire a 12V DC siren to sound when the push button paired to Zone 4 is triggered.
What you will need:
- A LRA transmitter (push button, door contact, etc.) paired to zone 4 of the LRA-DCRX receiver.
- 12V DC siren
- Extra wire (as needed)
- External power device used to power the 12V DC siren. In this example, we are using a 16.5 VAC /40VA Class II plugin transformer. Please make sure the power supply you use will supply the necessary power to the external device.
- Ensure the power supply is unplugged.
- Wire one wire of the siren into one of the "normally open" connectors on the back of the receiver (see image below).
- Wire the other wire of the siren to the plug-in transformer (see image below).
- Take a wire and connect one end to the other slot of the "normally open" relay.
- Take the other end of that same wire and connect it to the transformer (see image below).
- Plug in the transformer. Ensure the receiver is powered on--test.
