Section 3: Installation
3.1 Preparing for Installation
Choose a location for the NCA-2 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 appro-
priate knockouts. (Refer to Section 3.13 “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.
• Installers should be familiar with the standards and codes specified in Section 1.1 “Standards and Specifications”.
• 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”.
