Alerton has a building management system called Ascent that uses BACtalk and the Tridium Niagara framework for management control. According to the manual the web interface (called BCM-WEB) has default administrative credentials:
Admin user profile
You can log on to a BCM-WEB with a pre-defined admin user profile. It serves the same purpose as the local admin user profile in Envision for BACtalk – allowing the admin user to perform User Setup and General System Setup functions. The initial password for the admin user profile is “pass” and can be changed by anyone with sufficient privileges, so be sure you know the password
before saving user data from BCM-WEB to Envision for BACtalk. This password should be changed as soon as possible after installation.
