Definition
NO (Normally Open)
- This is a contact which remains open (as default) until activated, during the
"active" state the contact provides a closed circuit and starts conducting.
NC (Normally Closed)
- Is the opposite of a NO contact. The contact will remain closed (as default)
until activated, during the "active" state the circuit breaks and stops current flow.
Setup Example
Exit buttons are used in access control
systems to provide a momentary contact
signal to the access controller to open a
magnetic lock.
This example shows a "Fail-safe"
scenario. When the exit button is
activated the access control power
supply then releases power from the
lock, and if power is lost then the lock
also releases.
Wire in NO or NC depending on the
access controller used and also on the
required state of the lock during a "Fail-
safe" or "Fail-secure" scenario.
Connections - ACC351-352, ACC361-362
For operation with a door access control panel and lock, the exit
button is wired with NC or NO and COM.
A permanent DC 12-24V supply is required to operate the contactless
exit buttons (not supplied with the product).
