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.
