5 Functions
Manually unlock function (auxiliary release)
The manual unlock function (auxiliary release according to EN ISO 14119) is achieved by using a tool
and is to be used in exceptional circumstances. The release can be protected by use of a tamper
coating to prevent unintended operation. If operated, this tamper protection is damaged and
must be restored to ensure protection.
For the stainless-steel versions, MKey8ZRF…, there is a special tool, please see accessories.
Escape release
Where the Risk Assessment for the application permits, non-latching escape release versions of
the MKey RFID series enable quick release of the switch lock in case of emergency. The switch can
be mounted such that access to the release button is available from inside the active guard area.
Pressing and holding the release button will release the lock mechanism and open the lock
monitoring contacts, whilst the guard can be pushed open. Measures should be taken to reduce
the risk of improper activation.
LED Indicator lights
The MKey RFID switch is fitted with four LED indicator lights as follows.
