D.4.2 To Test Detectors Set Below 0.50% Obscuration per Foot
Using alarm sensitivities below 0.50% obscuration per foot requires a 90-day test to ensure that the
detector environment is suitable for the higher sensitivity setting. To meet Notifier and
Underwriters Laboratory requirements, test each detector planned to operate below 0.50%/ft
obscuration as follows:

* Detectors are suitable for open area protection within the listed air velocity range. Typically, this range is 0 - 4,000 ft/min for
photoelectric detectors and 0 - 1,200 ft/min for ionization detectors. Be sure to confirm this range before installing the
detector by referring to the manufacturer’s installation instructions.
† Use only alarm sensitivity setting of AL=1, AL=2 or AL=3 for ION detectors installed in Canada.
‡ 1% max. on CLIP. Larger figures may display.
** The use of alarm sensitivities below 0.50% obscuration per foot requires a 90 day test to ensure that the environment for the detectors
is suitable for the higher sensitivity setting. (Refer to “To Test Detectors Set Below 0.50% Obscuration per Foot” on page 114.)
†† Refer to the beam detector manual to determine the alarm settings: they are a function of the distance between the detector
and its reflector. There is no Prealarm for beam detectors in CLIP mode.
