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,

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.

Function 60 - Code 10 action code.

Summary of Action Codes

2 Lock operates only if Time contacts are closed (Zone 1)

3 Lock operates only if Time contacts are open (Zone 2)

1 2 ... 5 6 7 8 9 10 11 12 13 14 15 ... 22 23
