CAUTION
WARNING
IMPORTANT
If the lock will not respond to any keycard (including the
Emergency keycard), there are four options that should be
attempted to open the door. In order, they are:
1. Verify the batteries, and replace them if they are providing
less than 4 Volts total. Use the Emergency keycard.
2. Use the electronic override feature (requires FDU and
communication cable or ATLAS M-Unit and IPM).
3. Use mechanical key override if locking system has one (see
section 9, step 8).
4. Contact Technical Support for instructions on using the
drill point.
Electronic Override Using the FDU:
If the reader fails, the E-760/770/790 lock can be opened
using the FDU (Front Desk Unit). The lock must have been
initialized by a valid FDU from the hotel where it is installed
(i.e. with the correct internal and external hotel codes), be-
fore the electronic override can be used.
Electronic Override Using ATLAS:
Refer to ATLAS User Guide.
There are two possible security levels:
Low security: IF an FDU with a software version lower than
V2.01 overrides the lock, the lock audit records only the date
and time.
High security: IF an FDU with version V2.01 or higher soft-
ware overrides the lock, the lock audit records the FDU num-
ber, the Authorization keycard number, the date and the
time.
