OTCaccess C5 introduction
Dear field operator,
We are introducing you to OTCaccess C5 –new generation, smart lock system, designed to ease
the access process as well as secure valuable assets.
OTCaccess is a unique access management solution developed by BVK Technology. It is
designed to manage multiple scattered access points (places that need to be accessed) with
OTCs (One Time Codes).
An OTC is a One Time Code used by a field operator to unlock a certain location. The OTCs are
generated based on the person who is going to use it (a certain field operator), the lock that needs
to be accessed, the starting time within which the field operator will access and the action to be
taken at the lock (unlock, exit penalty mode, manually synchronize the time of the device, etc.).
Therefore, in case one of this factor is wrong at the moment of entrance, an OTC could be either
generated in advance or requested at the moment of access.
A field operator, the person who will unlock the lock, is defined by a PIN-code. Each PIN-code is
unique and cannot be shared with other field operators. A PIN-code may or may not include autho-
rization level of the field operator depending the corporate policies. Please ask your administration
about your status.
OTCaccess locks are designed to work in offline environments, however, once connected to the
network, all the actions taken regarding the lock will be real-time monitorable by the monitoring
center.

OTCaccess locks contain an inner clock named RTC. The clocks must be kept
up to date since OTCs are time sensitive. In case the lock runs in offline mode
for a long time it is natural that the time value may shift. If lock’s time shifted/is
wrong, the OTC will not be valid. You can check the actual time value of the lock
as it is shown on keypad’s display.

Time Delay
After entrance of a valid OTC, the system might make you wait for a certain
period of time before it opens the lock. This waiting period is called “Time Delay”.
It is especially useful in Burglar Alarm cases (Check Burglar Alarm section)
Opening Window
After entrance of a valid OTC, and Time Delay period is ended, the lock waits for
a certain period of time for you to enter your OTC one more time, to confirm that
you are in front of the door and you still want to enter. This period of time is
called “Opening Window”
Troubleshoot
OTC Invalid
a. PIN-code might be entered wrong
Try to re-enter your Function, PIN code and OTC combination. In case you get the same
error and you are sure that system clock, the function code and your OTC are all correct,
contact your administrator and ask him to reset your PIN-code and generate a new OTC
for you.
13 www.bvktechnology.com
Time Lock
Time lock is the feature of the lock, that disables entrance outside working hours
or days.
The lock will not accept any OTCs unless the system is within working hours.
Please contact your administrator whether one or multiple time lock settings exist
at the locks.

b. OTC might be entered wrong
Try to re-enter your Function, PIN code and OTC combination. In case you get the same error
and you are sure that your PIN-code is right, the system clock is correct, you are entering the
right function & PIN code for that OTC and try re-entering. In case you still get the same error,
contact your administrator and ask him to generate a new OTC for you.
c. The OTC was used previously
OTCs can be used only once. If you re-enter the same OTC, it will not be valid. Ask your admi-
nistrator for a new OTC.
Note: There may be some cases where opening codes can be used multiple times within the set
time period. Assume you are provided a One-Time Code (OTC) unless otherwise stated.
d. OTC duration exceeded.
Each OTC has a validity period called “duration”. When you receive an e-mail or SMS with your
OTC, the time until it’s valid will be stated in the message. In case you exceeded the duration of
the OTC, ask your administrator for a new OTC.
e. OTC is generated for wrong lock/user.
Before using the OTC, make sure that the OTC is generated for you and for the namely lock you
want to unlock. These are stated in e-mail and SMS message you received for the new OTC. In
case you get the same error ask your administrator for a new OTC.
f. Lock system’s time is wrong
Check the time on the keypad. It should be displaying the right local time. OTCs are time sensi-
tive. If the time on the screen is wrong, make sure to perform “Manual Time Synch” operation,
before re-entering your OTC.
g. Lock system might be in 2nd Penalty Mode
Check the error message on the keypad. In case it displays “2nd Penalty Mode” error message,
make sure to perform “Penalty Mode Off” operation (check 2nd penalty mode section) before
re-entering your OTC.

OTC is valid, but lock doesn’t open
a. Make sure the lock is not stuck. In case you try to turn the knob (handle) of the safe or force
the lock to open the door before the beep sound is fully heard, you may cause the lock to stuck.
Please make sure 2 short and 1 long beep are clearly heard, then turn the knob or lock handle
gently. The lock will be giving you enough time to open before it stops triggering.
b. Check the keypad’s screen for which lock is getting unlocked after entering the OTC. Make
sure you are at the right door.
c. Check the keypad’s screen for any error messages.
d. Try turning the system off and on.
e. The lock might be harmed. Ask a technician for help.
How to open the lock during a power cut
The keypad has a 9V battery snap and a Type-C USB port. In case of power cuts, you might
use a 9V battery or a power bank with Type-C USB cable to power up the lock system. After the
system boots up, you can unlock with a valid OTC.
Note: In some scenarios some OTCs can unlock multiple locks at the same time (eg. Safe &
Top Box at once). While using a battery or power bank it is recommended to only open one lock
at a time. This will use the power source more efficiently.
