It does not specify where these signals should be placed or the photometric characteristics that they must possess. The Board solicited suggestions on these traits. A majority of commenters called for more accessibility, yet provided very no details about technical requirements.
Initiating devices
Initiating devices for fire alarm can be found in a variety of forms. They are comprised of heat and smoke detectors, smoke detectors for ducts and beam detectors.
