2.3.1 Controlling a Single Door or Gate
Relay 1 is typically used when the system will control a single door or vehicular gate operator. Note
that the electric strike and magnetic lock are each powered by their own power supply. Electric
strikes are connected through the normally open (NO) contact and magnetic locks are connected
through the normally closed (NC) contact.
