How to Change an Ionization Detector's Pre-Alarm and Alarm
Thresholds
Purpose: To change the pre-alarm and alarm thresholds of one or more
ionization detectors. The ionization detector is UL Listed and FM
Approved for alarm reporting anywhere within the obscuration range of
0.5 to 1.5 percent per foot when used for an open-area application.
Alarm thresholds can be set in 0.1 percent-per-foot increments. A pre-
alarm threshold can also be set anywhere within the obscuration range
of 0.5 to 1.4 percent per foot, but must be less than the detector's alarm
threshold. Two additional alarm-reporting ranges are defined for special
applications. The in-duct range refers to detector placement in an air
duct. The DH-2000 range refers to detector placement in a DH-2000
Duct Housing with associated sampling tubes to monitor the air in either
a supply- or return-air duct. The alarm ranges for these special
applications are as follows:
Application
Induct
DH-2000
Ionization detectors can be automatically programmed to change
alarm thresholds by time of day if they are configured for day/night
operation. The night alarm thresholds must be less than the
corresponding day thresholds.
