Concord 4 User Manual 23
Access code integrity
To preserve the integrity of your system, keep access codes confidential and
delete extra codes as soon as they are no longer needed. Avoid using obvious
code patterns such as 1234, 1111, 2222, etc.
When you use the system master code to enter user programming, you can:
• Change the system master code.
• Change or delete the partition master code in the current partition.
• Change or delete regular user codes in the current partition.
The default system master code is 1 2 3 4. It is important that you change this
default and record the new code (see “User codes” on page 72).
When you use the partition master code to enter user programming, you can:
• Change the partition master code in the current partition.
• Change or delete regular user codes in the current partition.
There are no default partition master codes. Record all codes (see “User codes”
on page 72).
You cannot enter user programming with a regular user code.
Touchpad tamper
The installer can program your system to activate a police alarm in the case of
possible touchpad tampering. If more than 40 keys are pressed when the system
asks for a code, and those keystrokes are not part of a valid access code, a siren
will sound. Talk to your installer or see “Alphanumeric and fixed display
touchpads” on page 73 to see if this feature is enabled.
Changing or deleting user codes
You can use a touchtone phone to change or delete user codes, but
alphanumeric or fixed display touchpads work much better because of their
extensive feedback capabilities.
Note: The system will not accept the same code for two different users. To
change system and partition master codes, see “Programming” on page 55.
To change or assign a user code:
1. Enter the programming menus by pressing 9, system or partition master
code.
2. For Concord 4 systems, press 030 nnn 0, where nnn is the user number (000
to 229). For Concord Express V4 systems, press 030 nn 0, where nn is the
user number (00 to 15).
3. Enter the desired four-digit code, and then press #.
