Changing the Code for a Vector 2000 Alarm

Vector 2000 alarm is a model of alarm system, which is manufactured by Ademco Security, a Singapore-based alarm company, before the production is discontinued. The system allows you to add alarm codes for employees or family members to arm and disarm the alarm. Although the codes cannot be changed, the codes can be replaced or deleted. If your codes have been known by someone outside your home or company, it is best to change your alarm code to new one. The process takes merely 5 minutes and secures your property much safer, here are the steps.


  1. To delete the existing code, enter the main code by using the number buttons on the control panel.

  5. Then, enter the number you want to replace, for example number “2” like the previous one.
