1 Codoor - General
Codoor 3500, a complete code lock suitable for fitting to a
single door, incorporates an electronic code lock, a mechanical
locking device and a power unit in the same housing. Codoor
may be fitted on most doors with handle operated ASSA type
mortice locks. When Codoor is fitted; the outside door handle is
disengaged and may be pressed down without opening the door.
To open the door, a 4-digit code has to be entered. The handle
on the inside of the door is not affected by Codoor, and works
normally for people leaving the premises. All programming,
except for setting of the programming code, is entered via the
keypad (see figure). Besides the keys, the keypad includes two
LEDs, one green and one red.
GREEN - In programming mode, the green
LED indicates that codes etc. have
been entered correctly. It also
confirms each key press in
programming mode.
RED - In operating mode, the red LED
confirms each key press.
In programming mode, the LED
flashes slowly until a command is
entered. Then the LED flashes
quickly.
Codoor also incorporates a buzzer, both to confirm each key press (if
required) and to indicate “battery low” by sounding a low tone (see
section Backup Power Supply). Otherwise, the buzzer sounds to
confirm successful programming.
The programming code must be set before the unit is fitted to the
door (see next page).

4 Fitting to door
1. Remove the cylinder ring and
the door handle from the door
by loosening the four screws.
2. The lever handle spindle
should project no more than
20 mm on the outside of the
door. If the spindle is too
long, push it through into the
handle on the inside. If this
cannot be done, cut the
spindle to the right length.
3. Screw the supplied
extension sleeves to the
nipples for the handle.
4. Place Codoor on the outside of
the door with the handle
attached, and pass the lever
handle spindle through the
square hole. Note! The red
mark on the follower should
always point downwards.
5. Tighten, not too hard, the four
previously loosened screws (the
screws for the handle first).

5 Install reinforcing spring
For Codoor’s mechanical release to work properly, the follower
spring in the lock case in the door must be capable of holding the
inside handle in a horizontal position. If the handle on the inside sags
(could be the result of the handle being screwed too tightly), or if the
follower spring in the lock case in the door appears weak, the
reinforcing spring supplied should be fitted. Follow these steps:
1. Put the outside door handle on the
Codoor unit.
2. Pass the lever handle spindle
through the square hole at the rear
of Codoor. Note: The red mark on
the follower should always point
downwards.
3. Door hung on the right:
Insert one end of the spring into the hole
on the spring holder, on the right in the
picture. Place the other end of the spring
on top of the end of the extension sleeve
that is on the left in the picture. The end
of the spring holder on the left should
then be bent into position under this end
of the extension sleeve.
4. Door hung on the left:
Insert one end of the spring into
the hole, on the right in the
picture. Unlike doors hung on the
right; the spring holder should be
adjacent to Codoor, with the
spring on top, as shown. Place the
other end of the spring holder on
top of the end of the extension
sleeve on the left, as shown. Then
bend the end of the spring on the
sleeve into position under this end
of the extension sleeve. If needed,
unscrew the sleeve some distance
from the fixing. This gives you a
longer projection to work with.
5. Fit Codoor to the door as described earlier (see section Fit to door).

9 Using Codoor
Access
1. Enter any of the programmed codes (without pressing ) and without
touching the door handle. At each key press, an audible signal is sounded
(if the buzzer is enabled) and the red LED on the keypad flashes once.
2. A click sound confirms that the code has been correctly entered.
3. The door must be opened within 4 seconds.
Leaving the premises
Codoor’s mechanical locking device only affects the outside
door handle. The door can always be opened from the inside as
usual.
Automatic resetting
Codoor has two separate resetting systems to return the lock to
the locked position after a code has been entered.
- Mechanical: the lock is reset each time the door handle is
used during access.
- Electronically: the lock is reset if the handle is not used
within 4 seconds of a code being entered.
This provides security against unauthorised access, since
Codoor can never be left in the unlocked position. However, it is
important to remember that Codoor should not be left in the
deactivated mode (see section Deactivation function).
Access blocking
To thwart attempts to obtain an access code by trial and error,
Codoor incorporates a blocking function to disable the unit after
16 false key presses (four successive incorrect 4-digit codes).
The unit remains blocked until 2 correct codes are entered
successively. This means that further instructions to users are
not required.
- 13 -
10 Testing
• It must always be possible to open the door from the inside.
• The handle on the outside should not be disengaged, and should
not open the door until the correct code is entered.
• When the correct code is entered, the handle on the outside should
activate the lock, but only once. As the handle is released, it
should again disengage.
• The handle on the outside must not be jammed in any position,
and should spring back up completely after being pressed down.
• If the code is entered, Codoor should automatically reset to the
disengaged position after about 4 seconds.
Test Mode
A test mode is implemented primarily to test and set up the unit, and
also for field service. The unit will remain in test mode until the
appropriate command is given to leave it. It is not necessary to put the
processor into SLEEP mode other than by specific function.
Entering test mode
Test mode is entered by holding the button in at the rear of the unit
and pressing * for at least 2 seconds. The buzzer will give a short beep
and the green LED will be lit continuously, unless otherwise stated, to
indicate test mode. Each time a key is pressed the buzzer should be
sounded and the red LED lit as per normal operation.
Pressing one of the keys as follows then enters each test.
Test modes
Button 1 Flashes the green and red LEDs simultaneously with the sounding of the
buzzer. This will continue until another key is pressed.
Button 2 Checks the RAM of the processor. If successful a confirm tone is given or
if unsuccessful an error tone is given. The unit returns to test mode with
the green LED continuously lit.
Button 3 Checks the non-volatile memory (non destructively). If successful a
confirm tone is given or if unsuccessful an error tone is given. The unit
returns to test mode with the green LED continuously lit.
Button 4 Fires the solenoid in and out every 4 seconds, the status of reed switch
sensor is given on the LEDs, with contact locked given by the green LED
and unlocked given by the red LED.
- 14 -
Button 5 Puts the unit into sleep mode to enable the current consumption of the unit
tobe measured. The unit will come out of this function when any key is
pressed.
Button 6 Only shows the status of the position sensor. Red LED – unit locked
(solenoid un-engaged), green LED - unit unlocked (solenoid engaged).
Button 7 Puts the unit into an unlocked state with the status of the position sensor
shown on the LEDs as previously stated.
Button 8 Shows the status of the low battery input. Low battery detected the red
LED will show. If the battery voltage is OK the green LED will show.
Button 9 Does nothing except beep and light the red LED.
Button * Does nothing except beep and light the red LED.
Button 0 Does nothing except beep and light the red LED.
Button # Exits test mode with a confirm tone, leaving all the data intact in the non-
volatile memory.
Reset By pressing and holding the reset for 2 seconds the Condor’s
button on memory button is cleared back to factory settings. E.G.
rear
• No programming code set.
• No access codes set.
• Buzzer enabled.
• Deactivation function enabled.
The reset function can only be used when in
test mode!
11 Backup power supply
When the batteries are running low, Codoor will operate with
the buzzer sounding a low tone. The lock has a backup power
supply sufficient for a limited number of openings once the
batteries have run down.
In order not to jeopardise security, the backup power supply is
restricted to 50 openings, after which the backup function is
terminated to conserve the remaining battery power. However,
to allow battery replacement to be carried out by the person in
charge, the programming code is not disabled, to allow the door
to be opened.
- 15 -
12 Changing the batteries
When the unit’s batteries run out, Codoor will stop working.
The lock has a backup power supply that will allow the door to
be opened a limited number of times, but the batteries should be
replaced as soon as they fail. Follow these steps:
1. Remove Codoor from the door.
2. Remove the batteries from the rectangular shaped holes on the lower part
of the back of the unit (2 batteries type U9VL).
3. Always change both batteries. Changing only one battery will
dramatically reduce the life of the new battery. The batteries should be
lithium type.
4. Re-fix the housing.
13 Erase memory
In cases where the Codoor is moved to another door (with new
users), you should be sure that no old codes remains. The best
way is to erase the memory. Proceed as follows:
1. Remove Codoor from the door.
2. Press and hold the reset button on the rear of Codoor
and - button simultaneously - until the green LED
lit.
3. Release both buttons simultaneously.
4. Press the reset button once again for 2 seconds.
5. As a confirmation, a rising tone sounds from the buzzer.
