• Local Operating Console (LOC) – Section 12.2.2.21.1: “Mass notification systems shall include a system operating console(s) for authorized occupants to readily access and originate messages in emergency situations.”
• Autonomous Control Unit (ACU) - Section 12.2.2.20.1: “the building autonomous control unit shall monitor and control the notification appliance network.” At the ACU, authorized personnel can initiate delivery of pre-recorded voice messages, provide live voice messages and instructions, and initiate visual strobe and alphanumeric message notification appliances.
• Fire Alarm Control Interface – Section 12.2.2.33.1.1: “Where a fire alarm system is installed covering all or part of the same building or other area as the mass notification system, an interface shall be provided between the systems for operational coordination purposes.” This connection will allow the ECS to override fire alarm audio and visual notification appliances.
• Interface to Other Systems and Alerting Sources – A variety of systems that “shall be permitted” to interface or connect with an ECS/MNS are discussed throughout the latest Chapter 12 draft, including air handling control, door control, elevator controls, public address systems and wide-area (outdoor) notification systems.
• Notification Appliance Network – This network consists of a set of audio speakers, strobes, and text signs (when required) that are located to alert occupants and provide intelligible voice and visual instructions. A number of these devices must be installed in adherence to ADA (Americans with Disabilities Act) requirements too.

In conformance with the latest draft of 2010 NFPA 72 codes, manufacturers like Gamewell-FCI have developed high-tech, low-cost combination fire alarm/ECS solutions for new construction and renovation applications.
