How to work with duress passcodes and avoid ‘Passcode in Use’ errors.

• Intrusion control panels provide a duress feature providing options for users to modify their user passcode and generate a duress alarm when necessary.
• When adding new codes, the last digit must not be within 2 numbers, higher or lower, than the last digit of any existing code. Otherwise adding a conflicting code is attempted and the “Passcode in Use" message is generated. This rule applies regardless of which duress option is in use.
  • For example, a “Passcode in Use” message is generated if adding any of the following codes is attempted while 1234 is used in the panel.
    • 1232
    • 1233
    • 1235
    • 1236
• Duress types 0-3 are  available for GV2 and higher panel types.  G series panel types only use Duress types 1 and 2.

Duress Type 0:

• Duress feature is disabled, only actual user codes will work for normal operation.

Duress type 1:

• Users add 1 to the last digit of their passcode to send a duress alarm report when they enter the passcode at a keypad.
  • Example:  If the passcode is 6123, entering 6124 activates a duress alarm. 
  • If the last digit of the passcode is 9, a duress alarm occurs when the user enters 0 as the last digit of the passcode.

Duress type 2:

• Users add 2 to the last digit of their passcode to send a duress alarm report when they enter the passcode at a keypad.
  • Example:  If the passcode is 6123, entering 6125 activates a duress alarm.
  • If the last digit of the passcode is 9, a duress alarm occurs when the user enters 1 as the last digit of the passcode.

Duress type 3:

• Send a Duress event when any passcode with the authority setting: Send Duress=YES is entered.
• When using Duress type 3 a single Duress code is added for all users.  This Duress code will be the only code using an authority level with the setting Send Duress=YES.
