Mass Notification Systems are Critical for Message Dissemination

Mass notification design requires a thorough understanding of the relevant codes and the client’s needs to ensure the system achieves the required capability for the specific application in a reliable manner. Emergency communications systems (ECS) encompass both fire emergency voice alarm communications systems (EVACS) and mass notification systems (MNS).The designs for these systems differ in that for fire EVACS the system must meet a prescribed set of requirements as outlined in NFPA 72, National Fire Alarm and Signaling Code®. Mass notification systems on the other hand generally require a performance based design approach involving a risk analysis. The established risk for a fire EVACS is obviously fire, a singular risk. Alternatively, a MNS must be integrated into an emergency response plan to be utilized for multiple risks such as weather emergencies, shooter on campus or other risks as determined by the stakeholders who will be responsible for implementing emergency procedures. JENSEN HUGHES engineers meet with the stakeholders to establish a risk analysis matrix to determine the scope of the mass notification system (MNS) design and how it will be incorporated into the emergency response plan (ERP).

Picture_Section 1 - Services_Design_Mass Notification SystemWhether a college or university or business complex, one of the challenges any design must meet is that the messages are delivered effectively, campus wide. JENSEN HUGHES engineers work closely with the stakeholders to ensure the message templates meet their needs and then design the MNS to ensure they are delivered effectively and on time throughout the campus setting using multiple layers of notification means and methods.

In order for JENSEN HUGHES to develop an effective MNS for our clients, we strive to integrate campus wide MNS performance based solutions that not only ensure compliance with NFPA 72 but will be cost effective and reliable.  JENSEN HUGHES engineers ensure that all MNS and fire EVACS designs will meet both the audibility and intelligibility requirements of NFPA 72, as well as ensuring a performance based approach to universal design and meeting or exceeding ADA requirements.  We perform condition assessments or gap analyses to assess existing alarm systems, public address systems, and IT infrastructure to determine the most cost-effective solutions to meet the client’s MNS needs.

JENSEN HUGHES engineers also ensure the MNS command center and its back-up design and operation will meet the needs established by the stakeholders in the risk analysis and ERP development. JENSEN HUGHES offers the most experienced engineers to serve your fire EVACS and MNS design needs. JENSEN HUGHES engineers participate in the code process for these systems and have written the first book on MNS design titled Designing Mass Notification Systems – A Pathway to Effective Communications, published by the National Fire Protection Association.
