transfer opening in a wall, a spot-type detector
shall be installed within 5 feet (1524 mm) hori-
zontally of the damper. The detector shall be
listed for releasing service if used for direct inter-
face with the damper.

4. Where a smoke damper is installed in a corridor
wall or ceiling, the damper shall be permitted to
