    User Guide: Aspirating Smoke Detector Pipe Installation Scope of this user guide The purpose of this user guide is to provide details on the physical installation of the pipe network for the FAAST Fire Alarm Aspiration Sensing Technology aspirating smoke detector. Local codes and regulations may vary and take precedence over the information ®...
  • Page 4: Pipe Overview

    The FAAST detector has a built in tiered Unions can also be used to orient sample ports correctly in insertion point for the pipes which allows for an outside tube a specific section of the pipe network, such as over return diameter of either 1.050"...

    User Guide: Aspirating Smoke Detector Pipe Installation End Caps Mounting Brackets The end of the pipe should be terminated with an end cap. The The pipe network is mounted to the ceiling, or other appropriate end cap may have a sampling port depending on the system location, using mounting brackets.

    • Gather all relevant information about the site, including conjunction with the FAAST system. It contains design the floor plan for the protected space. The floor plan must considerations and recommendations on how the FAAST also include existing or proposed fixtures, fittings, air system may be installed in various applications.

    All pipe designs must have an end cap. Sampling Port Ceiling Tiles Multiple shorter pipes provide better performance than a single longer pipe. Symmetrical (Balanced) designs in pipe length, port size, Figure 11: Capillary tube sampling. and port distribution are preferred to optimize FAAST system performance. firealarmresources.com...

    Often, the temperature of the cold room is outside the operating network on the ceiling. The vertical sampling pipe should temperature of FAAST and the device must be mounted outside have sampling ports at various heights to sample within any of the room with the pipe network being run in to the protected stratification layers present in the area, as shown in figure 20.

    User Guide: Aspirating Smoke Detector Pipe Installation High Air Exchange Areas Generally the FAAST detector should not monitor more than Typically, high air exchange areas have some form of two air handling units. When monitoring multiple units with one mechanical ventilation to maintain constant or cyclical air device, the AHUs should have similar flow at all times.
