24System Wiring
© 2011 Apollo Security Inc.
The diagram below illustrates connection of a DC powered, Fail-Secure, door strike. This type of strike
requires power to release the door. The power will be supplied through the normally open (NO) relay contact
of the strike relay. No power will be provided to the strike until the reader activates the internal relay. The
reader will activate the relay as a result of a valid access request (card swipe, card swipe plus valid PIN,
valid PIN entry only, etc.). The reader will also permanently activate the strike relay if commanded by the
host software to be “unlocked”. The reader may also be configured to activate the relay if the exit pushbutton
is depressed. Some software systems may allow configuration of this feature (activate strike relay on exit
pushbutton) and others may not.
