CS106/BL106 Combined Door Entry and Coded Access

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.
