Lock Wiring Configurations
16
You have the option of wiring to the normally open (NO) connector of
Relay 2 if you want to have the Magnetic lock unlock under those
conditions. If you use the normally open (NO) connector then Relay 2
will have to be normally energized using the C•CURE Administration
application.
If the power supply fails, the magnetic lock will unlock regardless of
whether the normally closed (NC) or normally open (NO) is used.
Electric Strikes Unlike magnetic locks, electric strike locks typically lock when not
powered and unlock when powered.
You must decide if you want to wire for “fail-secure” or “fail-safe.” Fail-
secure means that if there is a power failure, the door goes to a secure or
locked state. Fail-safe (fail-open) means that the door is open if there is a
failure. It is important that local codes be followed to avoid people
getting trapped in an emergency situation. Usually fail-secure doors have
crash bars to allow emergency egress.
Using Relay 2 for an
Electric Strike
The same internal connections that are used for a magnetic lock can be
used to wire an electric strike. Connect the plus side of the power supply
to the normally open (NO) connection of Relay 2 and connect the
remaining external connections the same as the magnetic lock
