General Description
The C106 Coded Access Controller is a high quality, versatile security product,
controlling access to a door by means of a keypad and an electric lock release
mechanism.
Basic Operation
The C106 Keypad may be programmed with up to 10 unique access codes. If
a valid code is entered on the keypad, the lock release will operate for a preset
duration.
The keypad has one green and one red LED to indicate the system status to the
user; the green LED indicates that the lock release is operating, whilst the red
LED indicates an invalid entry.
Other Features:
Multiple codes
The C106 has 10 access codes available each of which can be 1 to 8 digits long.
The extra codes are provided for a variety of possible uses:
• Multi user applications, e.g. for a small office block.
• Time restricted access (described below).
Time-Restricted Access (Sta /Executive Operation)
Any of the 10 access codes may be programmed to operate during a restricted

CS106/BL106 Combined Door Entry and Coded Access
7
time period only. This time period can be determined by a time clock or
manually via a key switch.
For example, with factory settings, the operation of code 1 is unrestricted
(Executive Code) whilst code 2 is restricted to when the time clock input is
closed (Zone 1 Staff Code).
Codes can also be programmed to operate during alternate shifts. e.g. code 1
operates when the time clock input is open (Zone 2) and code 2 operates when
the time clock input is closed (Zone 1).
Refer to ‘Programming the Action Codes’ page 20 and Table 1 page 25 for
further details.
Exit Facility
The Exit facility enables the lock release to be operated directly from a
push button for the predetermined lock duration. Typically this would be used
to allow personnel to freely exit through the controlled door. The facility may
also be used for a Fireman’s’ key switch, or to interface with other security
products such as a Door Entry Telephone System.
Lock Delay
If required, the lock release can be programmed to operate after a preset time
delay, following entry of the access code. This function is useful if the keypad
is located a significant distance from the entrance.
Non-Volatile Memory
The access codes and user programs are stored in a protected non volatile
EEPROM memory, which does not rely on batteries. The access codes and
other programmable parameters are retained indefinitely without power

Power Supply - Important Sa ety In ormation
The Model 340C Power Supply must be wall mounted on to plasterboard, wood
or a similar non conductive material, in a protected indoor environment and
close to a 240V AC electrical supply e.g. an electrical cupboard. Connections
to the 240V AC mains supply must be carried out by a qualified electrician or
similar competent person, and made in accordance with accepted safety
practices.
A two pole switch (as provided by a Consumer Unit or Switch Fuse) must be
included to isolate both Live and Neutral during Installation or Maintenance. The
circuit must be protected by a fuse or other current limiting device, rated
according to the capacity of the cable used, up to a maximum of 10A.
Fuse
There is no serviceable fuse inside the model 340C Power Supply. It has an
electronic current / thermal limit which will recover when a fault is removed.

Electric Lock Release
When installing lock releases please allow a little movement on the door as
operation will be impaired if fitted too tightly.
The C106 Keypad provides two alternative pairs of connections for direct
connection of an electric lock releases:
‘FAIL SECR’ : Use these connections for ‘Fail Secure’ lock releases. These
devices require power to release the lock and will secure the door in the event of
power failure. These are the most commonly used lock releases.
‘FAIL SAFE’: Use these connections for ‘Fail Safe’ lock releases and magnetic
locks. Both of these devices require continuous power to lock the door and will
release the door if power fails.
Note
Any magnetic lock (Maglock) must be fitted with a suitable transient voltage
suppressor, e.g. a diode or MOV. Please contact the manufacturer of the
Maglock to check
These outputs are rated at the input voltage (12V  ) with a maximum current
consumption of 0.5A.

CS106/BL106 Combined Door Entry and Coded Access
14
High Current Lock Releases
For a lock release or a magnetic lock rated higher than 0.5A an additional power
supply will be required. In addition a relay must be used to interface with the
C106 Keypad.
The relay contacts, or the lock release, must be fitted with a suitable
suppression device to prevent voltage transient and electromagnetic
interference being generated by the coil of the lock release. (Refer to
manufacturer for further advice).
Consideration should be given to the problem of a voltage drop at the lock
release. Please refer to the manufacturer of the particular lock release for
information on suitable cable length versus thickness and power supply rating.

Time Restricted Access
The C105 Keypad has a pair of terminals marked ‘TIME’ which can be
connected to an external Time Clock or Key switch to control time restricted
access. Any switch contact must be fully isolated (i.e. voltage free), the
TS2000 BST Time Clock is normally used.
Access codes may be programmed as follows:
Access
Time Switch Status
Usage
No Restriction Executive
Zone 1 Contact Closed Staff (shift 1)
Zone 2 Contact Open Staff (shift 2)
Exit Button
The terminal marked ‘EXIT’ may be connected to an external push button (e.g.
5077 switch) for ‘push to exit’ operation. Momentarily operating this button will
directly operate the lock release for the programmed duration.
Alternatively, the input may be used with a Fireman’s Override key switch,
which should be of the normally open type. If this feature is to be used it is
important that the lock release be of a continuously rated design.
In general, a switch connected to the ‘EXIT’ terminals should be fully isolated i.e.
Voltage free.

Programming the C106 Keypad
General
The 10 access codes, lock time etc, are all programmed via the keypad. To
prevent unauthorised use, a security key (1 8 digits) must be entered.
The basic principle of programming is as follows:
Each program function is described in detail on the following pages.
Procedure
■ Enter the security key (1 to 8 digit number, default 1212). Check
the red LED flashes continuously.
■ Enter a key sequence on the keypad.
■ Observe both the red and green LEDs flash for one second.
■ When all functions are programmed, exit program mode by
pressing

Programming a New Access Code (Functions 1 to 10)
The C106 Keypad has ten access codes. Each code may be between 1 to 8
digits long.
NOTE
By default code 2 will only work when the TIME terminals are shorted and codes
3 to 10 are disabled. The Action codes should be adjusted as required, refer to
page 20
Procedure
 Enter the current Security
key (default 1212). Check
the red LED flashes
continuously.
 Type :

Changing the Security key (Function 91)
The security key is the code that must be entered on the keypad to gain access
to the settings.
The security key is factory set to 1212, to maintain security we recommend that
this be changed immediately.
To ensure an adequate level of security it is recommended that a minimum of 4
digits be used for the security key, giving 10,000 combinations.
Procedure
 Enter the current Security
key.
 Type :

Choosing an access code
To ensure an adequate level of security it is recommended that a minimum of 4
digits be used for each access code, giving 10,000 combinations. Codes
should be chosen carefully to avoid obvious sequences and repetitions (e.g.
12345, 258, and 4444) which may be easily guessed or discovered. Try to
choose codes with a random appearance (e.g. 6149, 186403) and avoid
telephone numbers and other meaningful codes which, again, may be guessed
by a would be intruder. It is also a good idea to regularly change the access
codes.
When choosing access codes it is important that no code is a subset of another
code, e.g. If code 1 = 234 and the code 2 = 12345, code 2 would never open
the door as 234 is a subset of 12345.
Maintenance
It is important also that the keypad be regularly cleaned to remove finger marks
which may give clues as to the access code. Use a soft cloth moistened with
dilute detergent. Do not use organic solvents or any other cleaner.

Programming the Action Codes (Functions 51 to 60)
Each access code has an associated action number. This is a single digit from
0 3 which determines the action that occurs following the entry of that access
code.
Function 51 Code 1 action code.
Function 52 Code 2 action code.
