Each detector provides a host of selectable intelligent options. You can program
Pre-Alarm and Alarm detector sensitivity levels (Table 38) in the widest allowed ranges
(0.03 to 4% per foot obscuration). The AFP-300/AFP-400 provides nine levels of
Pre-Alarm (PA:1–PA:9) and Alarm (AL:1–AL:9) in percent per foot obscuration:
•
3$ a self-optimizing setting where the control panel selects a suitable Pre-Alarm
level for a detector.
•
3$²3$ selects the detector Pre-Alarm sensitivity level—with PA:2 the most
sensitive and PA:9 the least sensitive. (PA:0 = no Pre-Alarm).
•
$/²$/ selects the detector Alarm sensitivity level—with AL:1 the most
sensitive and AL:9 the least sensitive.

Notes:
1.
* Signifies the factory default setting.
2.
The use of alarm sensitivities below 0.50%/ft obscuration requires a 90 day test to ensure that the
environment for the detectors is suitable for the higher sensitivity setting. (Refer to “Testing Detectors Set
Below 0.50%” on page 40.)
3.
Suitable for open area protection only with 0 to 300 feet per minute air velocity.
