5.1. PASSWORD SECURITY DESCRIPTION (USERS ADMIN)
To prevent un-authorized access, users are required to “Login” in order to:
- Acknowledge and reset alarms
- Change operating modes
- Change Configuration settings
- Manage Users
- Map Inputs/Outputs
The device security is organized in groups. Using the Users Management screen a device
Administrator can create new users, enable and disable access for existing users. There is
one default user created for every group: admin, power and user. Is the responsibility of the
installer to make sure the default passwords are changed during ATS commissioning.

Note on Privacy: The GHC is not storing user passwords. Using an encryption mechanism a
hash of the UserID + Password+ encryption key is created and stored. During the login process
the UserID + the provided password + key is used to rebuild the hash and compare with the
stored one.
