Introduction / Tools and Materials Needed
Introduction
The MPC Cobra is a battery-powered manually programmed access control sys-
tem. Up to 100 individual codes can be programmed right at the keypad. A red and
green LED on the keypad provide visual indication for programming and access
events. Mechanical key override is possible when a 7-pin small-format inter-
changeable core (not included) is installed in place of the cylinder plug, which
comes standard. Either the plug or the IC core must be installed for the lock to
operate. When the cylinder is removed (using the cylinder control key) the lock
will unlock. Manual key override should only be necessary if the low battery out-
put indications have been ignored. (See also BATTERY INFORMATION: on page 10).
The design allows for mounting on doors from 1-1/2” to 2” thick. A shim is avail-
able to mount the lock to a 1-3/8” door. An exterior gasket (EG option) is available
for application to exterior sides of doors.

2. Allen wrench set
3. Loctite 242
4. 4 “AA” Batteries (provided)

Lock is now operational.
Operation:
Either the cylinder plug or the IC core must be installed for the lock to operate. Removal of the core or
p
lug automatically unlocks the lock. It is recommended that an IC core be installed in case it ever
b
ecomes necessary to unlock the lock using mechanical means.

Programming Lock Codes
57010-H Page 10 12-19-2005
Programming Lock C odes
CODE FUNCTIONS
:
The MPC Cobra is manually programmable to have up to 100 codes. The codes can have different functions as described below. Several
types of functions have factory default values which are operational as soon as the lock is installed. It is highly recommended that the Pro-
gramming Code be changed (this will delete all factory default codes) and new codes be added. In addition, it is recommended that at least
one Freeze/Lockout Code be added - in case the batteries get completely drained. (See “Battery Information” on below.) All codes can be 3-
8 digits in length (except the Programming code which must be 5-8 digits.) Keep a log of all issued codes. Issue codes exclusively with all
odd or all even numbers - this practice will make it easier to spot duplicate codes, since each keypad button represents two numbers (for
example, code 246 is identical to code 135.)
The programming code puts the lock into a programming mode. It will not unlock the lock.
When a Programming code plus “*” is entered the LEDs alternately flash several times
indicating the lock is in a programming mode. If more than 30 seconds pass in between
programming entries, the lock returns to a normal operational state.
XXX
Normal codes unlock the lock for the relock time delay. While the lock is unlocked the
green LED will flash. The LED will stop flashing and the lock will relock.
xxx
Toggle codes unlock the lock indefinitely. When the same (or another) toggle code is
entered, the lock will immediately relock. When a toggle code is entered, the green LED
will flash once. The LED will stop flashing and the lock will relock.
xxx
Freeze/Lockout codes prevent other codes from working. The lock can be locked or
unlocked when one is entered. If it is locked, a Pass Thru code will unlock it but all other
codes will not. Only another Lockout code will reverse the effect.
xxx
One Use codes unlock the lock for the relock time delay. They will only work once and
then are deleted from memory. They can used again if they are programmed (added) into
memory again.
Supervised codes require that two different supervised codes entered in order to unlock
the lock for the relock time delay.
xxx
Pass Thru codes will unlock the door for the relock time delay even if the door is in the
lockout mode.
CLEARING MEMORY:
Clearing memory will delete all programmed codes and restore factory default
codes. If the memory ever needs to be erased follow the steps below:
1. Remove the inside escutcheon. Remove one of the batteries.
2. Press any key.
3. Hold down the “*” key and reinstall the battery. Continue holding the “*” key
down. The red LED will flash a few times and then stay on.
4. Release the “*” key.
5. Install the inside escutcheon.
Note: to return the lock to the factory default relock time delay, do steps 1-4 twice
in a row.
BATTERY INFORMATION:
The MPC Cobra uses four, standard AA batteries.
The batteries should provide enough life for
approximately 80,000 lock/unlock cycles. When
the batteries are running out the lock provides two
different modes of low battery indication: First,
when a code is entered, the red LED will flash
twelve times before the lock executes the com-
mand of the code. This is an indication that it is
time to replace the batteries. The lock will go for
about 500 cycles in this condition. After it reaches
a certain point the lock will go into “Low Battery
Lockout” mode. A Freeze/Lockout code will need
to be entered in order gain access. If the batteries
are not changed, the lock will eventually not work
and manual key override (if installed) will need to
be used.
