The emergency buttons are suitable for unlocking a door in an emergency. The emergency button is triggered by pressing the white plate. It can then be easily reset using the key included in the delivery. Replacing the white plate is therefore not necessary. All models are supplied with 3 changeover contacts, red/green LED indication and a buzzer with adjustable volume. The emergency button is supplied as standard with a protective plastic frame and a magnetic contact to prevent unauthorized triggering of the emergency button. The magnetic contact switches the relay when the cover is opened, which allows external signaling.
