Unlocking; Opening The Door; Emergency Operation; Maintenance And Cleaning - HomeMatic HM-Sec-Key Montage- Und Bedienungsanleitung

If the error is only a fault that occurs during normal operation (because of
temperature influence for example), the jam can possible be eliminated by
attempting the locking procedure again.
8.1.2

Unlocking

The following describes operation on the device. The same behavior applies for
operation with a remote control and with the Centre but a different letter/number is
shown on the display.
Press the button "Unlock" on the door lock drive (top button). "M" is shown
on the display.
After the procedure is completed, two short signal tones are emitted on the
door lock drive.
8.1.3

Opening the door

This function is only possible if the pressure of the door seals is sufficient
to press the door open slightly,after the door lock drive has retracted the
opening latch.
The function can only be used from a hand transmitter or from the Centre.
The door behaves as if the latch was pressed.
Press the "Open door" button on the remote control forapproximately one second.
Press the "Open door" button on the remote control. The LC display shows
the flashing symbol "Unlock", the door lock drive retracts the opener latch.
The normal pressure of the door seal against the door opens the door
slightly.
The drive is then moved back to the neutral position and thesymbol
"Unlock" stops flashing.

Emergency operation

We recommend that you use a lock cylinder with emergency and hazard
functionality (double cylinder). These locks allow locking and unlocking from
the outside or inside independent of the other.
With a standard lock cylinder, the door can no longer beunlocked from the outside if
a key is inserted inside. If a defect occurs or the batteries are too low, the door can
no longer be opened without damaging it!

Locking/unlocking the lock can be done in the following two ways:
• From inside with the handwheel: In idle status, the door lock drive is
disengaged, i.e. mechanically separate from the key. By turning the hand-
wheel of the door lock drive, the lock can be locked or unlocked and the
door can also be opened. The function of the handwheel is therefore the
same is if you used a "normal" key. The door lock drive must be in idle
status (motor not moving).
• From outside with a key: In this case, a lock cylinder with emergency and
hazard functionality (double cylinder) is required, otherwise a key inserted
from inside will block any actuation of the lock cylinder. The lock can (if a
lock cylinder with emergency and hazard functionality is used) be locked or
unlocked from outside or the door can be opened with a key. The door lock
drive must be in idle status (motor not moving) in this case.
Do not tighten the screws that fasten the radio drive to the base too tight,
since it might jam the drive and make opening from outside difficult.

damaged housing. If you presume that proper operation is no longer
possible, disable the device. The device can be disabled to safeguard
against accidental operation, remove the batteries.
Hazardous operation is no longer possible in certain circumstances, if
• the device shows visible damage
