Guidelines for Fire alarm Installation Procedures

  • Understand the function of each device to be used in the system.
  • Refer design layout drawings Determine the appropriate location for the device based on site conditions without compromising its function. 
  • Update layout drawings to reflect the actual installation (as-built drawings).
  • Familiarize  with the wiring scheme and cable routes provided in the layout drawings, but adjust the cabling to suit the site conditions. Avoid routing cables near high voltage lines to prevent electromagnetic interference (EMI) and electromagnetic compatibility (EMC) issues that can affect data signaling in fire alarm systems. Ensure that the cables can withstand fire and perform their function effectively.
  • Mark cables with tags or labels according to the cable schedule, ensuring that fire alarm cables are clearly distinguished from other electrical/instrument cables.
  • Terminate each device according to the termination diagram provided.
  • Perform thorough checks for open circuits, short circuits, and loop resistance. Excessive loop resistance caused by loose terminations or poor-quality copper conductors can result in signal/power loss for the fire alarm devices. The loop resistance should not exceed the specified limit mentioned in the user manual.
  • Install the devices according to the device ID indicated in the layout diagram and device/zone tables.
  • Install the control panel, power it, configure it, and verify its function following the instructions in the manual.
  • Connect the loop cable stage by stage, perform automatic learning, and verify the device list against the layout drawings and device location table. Refer to the troubleshooting manual if any faults are detected.
  • Validate the function of each device stage by stage. Troubleshoot and rectify any issues according to the troubleshooting manual.
  • Connect all cables and verify the overall function of all devices.
  • Create as-built drawings and device location tables.
  • Prepare a maintenance manual.
  • Allow the system to run for six days and conduct random functional validations daily. Train the user on system operation and maintenance.
  • Hand over all documents, records, and the fully operational system to the user.
