CUSTOM ACTION MESSAGE: Enter the number of the Custom Action Message to be displayed
during alarm conditions for this point (refer to Figure 3.21 on page 37 for an example).
VIEW: Press this soft key to view the message associated with the number entered.
ACCEPT: Press to save the entries made on this screen.
Sensitivity
Detector sensitivity levels for alarm and prealarm are set at this screen, which displays when the
SENSITIVITY soft key is pressed at the Detector Point Programming (2) screen.
Figure 3.29 Detector Sensitivity Screen
The control panel provides nine levels of Prealarm and Alarm in percent per foot obscuration, with
the following two exceptions:
• for heat detectors, the settings are in degrees Centigrade.
• for beam detectors, there are only six levels of Alarm. There is no Prealarm for beam detectors
in CLIP mode.
Alarm sensitivity settings range from one to nine, with one representing the most sensitive alarm
level and nine the least sensitive.
Prealarm sensitivity settings range from zero to nine. Zero indicates no prealarm. A value of one
can be a self-optimizing setting where the control panel selects a suitable prealarm level for the
detector. Values one or two through nine represent decreasing sensitivity, with nine being the least
sensitive.
Refer to the section “Detector Sensitivity Settings” in Appendix D, “Intelligent Sensing
Applications” for a full description and a table of the nine sensitivity levels by detector type.
