Fire Alarm Construction Standards
Summary of Work
All new systems must be Underwriter's Laboratory (UL) Listed as part of the Johnson Controls (JCi) Simplex 4120 Network System.
Design a complete system, including controls, stations, speakers, heat detectors, smoke detectors, flow switches, door releases, and any other devices that are electrically a part of the system. All components of the system shall be of an approved type and shall be installed in accordance with the provisions of the latest revisions of the Ohio Basic Building Code (OBBC) and all Referenced Standards (NFPA 72) accepted by the OBBC listed in 4101:1-35-01 Referenced Standards and the American Disability Act (ADA). Each piece of equipment shall be approved and carry an UL label. Each control panel shall provide alarm and trouble locations at both the building control panel and the Public Safety Emergency Communication Center. The system in use at the University of Cincinnati is a JCi Simplex 4120 Network system.
Auditoriums or other areas of assembly with an occupancy greater than 300 will have a separate voice announcement control unit with microphone to serve that area of assembly. This unit will be for the sole purpose of emergency evacuation instructions, and will not be used for routine announcement purposes. The control will be located at the stage managers console, or other point, staffed by responsible personnel during use of the area. The control will allow emergency instructions to be given in the assembly area, while allowing the normal evacuation message to play simultaneously in the remainder of the building. In areas of assembly with permanently installed public address systems, the fire alarm will be interfaced with those public address systems. The interface may allow the fire alarm to override the public address with the emergency announcements, or may simply shut down the public address system during emergency announcements, depending upon the space and audibility requirements.
Renovation of Occupied Buildings
When occupied buildings are being renovated, fire alarm devices that have been physically removed due to the renovations, shall also be removed from the fire alarm system immediately or no later than one week after removal.
ACCEPTANCE BY THE UNIVERSITY: The system shall be demonstrated in the presence of the University’s Project/Construction Manager in conjunction with the Department of Public Safety (Fire Prevention and Protection Systems), State of Ohio fire/building representative(s), and appropriate municipal fire/building representative(s).
