Initial calibration
NOTE 1: If calibration does not proceed according to the instructions
below, please see the troubleshooting section at the end of the manual.
NOTE 2: Initial calibration can be performed with a 12-V battery for
installations in facilities that do not yet have commercially-available power.
NOTE 3: Access control systems may register DPS and/or
BOND error conditions during the calibration sequence.
TECH TIP: For installation on a door without a door handle, a pull handle can
be made from masking or other tape to pull the door closed for calibration.
The DEM680E performs an automatic calibration
when the unit is initially powered up. This process only
proceeds if the door is closed and the unit has received
acceptable signals from the DPS and bond sensors.
PERFORM a manual calibration immediately
following installation, if necessary.
1
ENSURE that the door is closed.
2
APPLY power to the Magnalock.
3
PRESS AND RELEASE the calibration button (see
Diagram 34
).
4
VERIFY that the LED changes from red to amber
to green. The unit is now calibrated.
