authorised for deadbolt lock mode (permanently open). The door terminal is locked again
when a user key authorised for deadbolt lock mode is presented again.
Permanent deadbolt lock mode (toggle mode)
In permanent deadbolt lock mode, the terminal changes its locking status (permanently open /
closed) each time an authorised user key is presented.
