Each detector provides a host of selectable intelligent options. You can program
Pre-Alarm and Alarm detector sensitivity levels (Table 40) in the widest allowed ranges
(0.03 to 4% obscuration per foot). The AFC-600 provides nine levels of Pre-Alarm
(PA:1–PA:9) and Alarm (AL:1–AL:9) in percent per foot obscuration:
•
PA:0
no Pre-Alarm selection
•
PA:1
the self-optimizing setting where the control panel selects a suitable
Pre-Alarm level for a detector
•
PA:2–PA:9
the detector Pre-Alarm sensitivity level—with PA:2 the most sensitive
and PA:9 the least sensitive
•
AL:1–AL:9
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% 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 “How to Test Detectors Set
Below 0.50% Obscuration per Foot” on page 80.)
3. Suitable for open area protection only with 0 to 300 feet per minute air velocity.
4. Use only Alarm sensitivity setting of AL=1, AL=2 or AL=3 for Ion detectors installed in Canada.
