The Carrier ATS Master Series combines both access control and intruder alarm panels in a single panel. ATS Master Series panels, which allow you to manage and monitor these systems more effectively by collecting the access control and burglar alarm systems used in many modern facilities today under a single panel, offer an advanced security level in all your medium and large scale commercial and industrial facilities thanks to their modular structure and wide field equipment. ATS Card Access Control Systems can expand up to 64 doors, 256 zones and 65535 users with a single panel thanks to their modular structure, and multiple panels can be monitored under a single interface through the Advisor Management software thanks to the TCP/IP network output on all panels.
