How can I wire two(2) EBDK's to a single Fire Alarm relay so that in an emergency state, both EBDK's will be triggered?
NOTE: This procedure will only work if you are using a Normally Closed Dry Contact for the Fire Alarm relay. Normally open will not function in this particular setup.
Wire the fire alarm relay to Input and V Out of EBDK #1. Use NC(normally closed) and Common from an output on EBDK 1 to wire into the fire alarm Input and Common on EBDK 2.
This will allow the Fire Alarm to trigger both EBDK's into emergency. However, if EBDK 2 loses power, it will trigger its outputs, but will not put EBDK 1 into emergency as well.
