Autocall TrueAlert ES Addressable Notification Study Report

Functionality Cost Effectiveness of Smart Technologies Incorporating Addressable Fire Notification Graduate Student Independent Study Project Protection Engineering Graduate Students Polytechnic Institute Puchovsky PE FSFPE of Practice of Fire Protection Engineering Polytechnic Institute by Cyr Parrow to 14 2021 Summary have continued to become smarter over time incorporating a variety of sensors to collect and control different processes By monitoring ambient and changing conditions occupancy and energy demands building owners can save money and provide a more comfortable and environment for occupants Today fire alarm systems are also interfaced to control certain operations within the building such as elevator recall or HVAC shutdown Addressable appliances present an opportunity to further increase the functionality and usefulness fire alarm systems A system employing addressable notification appliances can be utilized to personalized messages to select areas of the building with nearly unlimited flexibility notable features of the addressable notification equipment include regulated 29 VDC power ability to T tap circuitry self testing capabilities and lower current draws for each appliance of these features can result in significant cost savings when compared to a conventional system this project the team was tasked with investigating the increased functionality and cost of addressable notification systems manufactured by Johnson Controls International for two different building uses JCI provided a fire alarm system layout for a high rise hotel and requested that wiring diagrams be prepared for two systems one utilizing notification appliances and the other using addressable notification appliances The of this exercise was to develop shop level drawings that could be used for cost estimating and to demonstrate the advantages of the addressable notification system After the system layouts the two sets of drawings were submitted to a third party electrical for pricing Based on these cost estimates it was determined that a fire alarm system addressable notification for the hotel building would be 45,700 9.15 less expensive a system with conventional notification appliances of the same layout The two major were that the cost of equipment and wiring for each system are virtually the same and major cost savings are a result of the significantly reduced number of labor hours 900 hours required to install the system with addressable notification appliances project team was also tasked with providing a high level fire alarm notification design for a school building and elaborating on the functional differences between conventional and notification systems in an educational building The team then produced a code notification design for the school building and determined the differences in control required for each system Through this exercise the team was able to discuss the of a conventional notification system caused by physical circuitry and highlight the of an addressable notification system in a building with ever changing emergency to plan for The capabilities of the addressable and conventional systems were then by considering a series of conditions that may occur during a weather related emergency of Contents Summary i of Contents ii of Tables iv of Figures iv of Acronyms v of Appendices vi vii Introduction 1 Background 3 Relevant Code Requirements 3 Detection in Sleeping Rooms 3 Notification 4 Inspection Testing and Maintenance 4 Class Designations Based on Circuit Integrity 5 Conventional vs Addressable Circuits 6 Evacuation Strategies 7 Literature Review 8 Hotel Study 10 Design Approach 10 Results 13 Discussion 15 Equipment and Wiring 15 Labor Hours 18 Evacuation Strategies 21 Conclusions 21 High School Study 23 Minimum Code Requirements 24 Design Options 25 Conventional System Schematic Design and Narrative 25 Addressable System Schematic Design and Narrative 28 Mass Notification and PA System Considerations 34 Discussion and Comparison of Design Options 37 Equipment 37 Functionality 38 Conclusions and Future Work 40 Cited 41 A Hotel Building Addressable Notification Wiring Diagrams 43 B Hotel Addressable Notification System Voltage Drop Calculations 57 C Hotel Building Conventional Notification Wiring Diagrams 80 D Hotel Conventional Notification System Voltage Drop Calculations 94 E Hotel Cost Estimate Quotes F Highschool Building Schematic Notification Design Drawings 106 G Highschool Schematic Notification Design Voltage Drop Calculations 118 H Simplex Notification Appliance and Equipment Cutsheets 121 I Project Presentation
