Section 3: Installation
3.1  Preparing for Installation
Choose a location for the fire alarm system that is clean, dry, and vibration-free with moderate 
temperature. The area should be readily accessible with sufficient room to easily install and 
maintain it. There should be sufficient space for cabinet door(s) to open completely.
Carefully unpack the system and inspect for shipping damage. Count the number of conductors 
needed for all devices and find the appropriate knockouts. (Refer to Section 3.11 “UL 
Power-limited Wiring Requirements” for selection guidelines.)
Before installing the fire alarm system, read the following:
• Review the installation precautions at the front of this manual, including temperature and 
humidity limits for the system (Page 3).
• All wiring must comply with the National and Local codes for fire alarm systems. 
• Do not draw wiring into the bottom 9 inches (22.86 cm) of the cabinet except when using a 
separate battery cabinet; this space is for internal battery installation.
• Review installation instructions in Section 3.2 “Installation Checklist”.  
3.1.1  Standards and Codes
In addition, installers should be familiar with the following standards and codes:
• NEC Article 300 Wiring Methods.
• NEC Article 760 Fire Protective Signaling Systems.
• Applicable Local and State Building Codes.
• Requirements of the Local Authority Having Jurisdiction.
