D.4.2: To Test Detectors Set Below 0.50% Obscuration Per Foot; D.5: Detector Status Display; D.5.1: Detector Maintenance Display - Honeywell nfs2-3030 Programming Manual

Intelligent Sensing Applications
* 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.
† For ION detectors installed in Canada: Use only an alarm sensitivity setting of AL=1, AL=2 or AL=3.
‡ 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 126.)
†† For Acclimate detectors installed in Canada:
‡‡ 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.
*** AL:6 and PA:6 are not available in CLIP mode.
****Within the 10 minute signature confirmation delay period, if there is a detection of another fire signature (Carbon Monoxide, Infrared
or Thermal) it overrides the 10 minute confirmation time.
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:
1. Set the detector as follows:
2. Operate detectors continuously for 90 days with all environmental factors (such as,
temperature, humidity, air flow, occupancy, and so on) similar to the intended application for
the detectors. Record all events for each tested detector with an electronic History buffer or a
printout.
3. At the end of the 90-day test: An authorized Notifier representative, or an end user trained by
an authorized Notifier representative must inspect the results of the test. If the test results show
no alarms or pre-alarms for the tested detectors, reprogram the fire alarm system to set the
Alarm sensitivity to the more sensitive Pre-Alarm level of the test.
D.5 Detector Status Display
D.5.1 Detector Maintenance Display
Should the panel detect a low chamber value or maintenance condition with a detector, it will
generate a point trouble as described in the operations manual for this panel. The following Read
Status screen displays detector information that applies to the state of the smoke detector. It can be
reached with the following commands, starting at the Main Menu screen:
• Press MAIN MENU
• Press READ STATUS
• Press READ STATUS POINT SELECT (enter the detector point address)
126
Use only the alarm settings of AL:1 or AL:2.
Step
1 Initially set to the 0.50% obscuration per foot Alarm level.
2 Set the Pre-Alarm level to the desired final Alarm sensitivity.
3 Set the Pre-Alarm to Alert mode (non-latching).
