Whether planning a new building or retrofitting an old one, a comprehensive design starts with a full review of the layout of your structure to determine which type of commercial fire alarm system and suppression devices should be incorporated. Proper placement and types of detection devices, alarms, and other warning equipment are essential to the safety of building occupants. Each element should be geared toward immediate detection and notification to implement the timely evacuation of occupants and quick response from the local fire department.
Local Code Requirements
Local authorities and municipalities impose somewhat different requirements for approval of a commercial fire alarm system. Moreover, the steps for approval may vary from place to place.
All designs should comply with local fire codes and NFPA-72 (National Fire Alarm and Signaling Code). One requirement is to have the design work. Installation, and testing completed by someone who can prove experience and certification for these systems. Proof of the designer’s experience will be submitted to the authority having jurisdiction (AHJ) at the outset.
Shop Drawings
Before approval, shop drawings should show the detail of the plan. No work can begin without approved permits.
The shop drawings should clearly represent each device and connection within the proposed system. The drawings will show elements such as the owner and location of the building, installation contractor, and dates of issue. Detail will include floor plans, riser diagrams, plus control panel, circuitry, and point-to-point wiring diagrams marked according to the NFPA 170 protocol.
The location of windows and doors and placement of each fire detection and notification device, monitor and control interfaces must be shown. Types of equipment attached to each electrical circuit must be defined, and backup power sources must be depicted.
Installation
The installing personnel should be licensed by a state or local authority or a nationally recognized organization. Alternatively, they should have been certified in a formal training program at the manufacturer's location.
Final Approval
When the installation is complete, the contractor or building owner will usually issue a written statement that the installation followed the proposed plan and met all manufacturer specifications.
Working with a fully licensed and qualified fire safety company for the design, installation, and maintenance of your commercial fire alarm system is the best route. Experienced companies like High Rise Security Systems in Chicago can help with each step of the way.
