Exit Buttons
This guide covers the slim exit buttons which are made from zinc
alloy with a matt finish. Their slim footprint means they can fit
most locations and come supplied with their own back box.
This guide also covers the compact exit buttons, just 53mm wide
with a built-in back box. The options available also include the
LED illuminated ACC253 model.

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
pressed 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.
