Heat Detector Sensitivity
Use this feature to set the temperature that heat detectors will respond. The range is 135° to
150° F. All detectors in the zone will respond in the same way.
The Model SD505-AHS Heat Detector is an absolute temperature device. This means that it
responds to an alarm immediately if the temperature in the zone goes above the programmed
temperature.
5. Enter the temperature that the heat detector will respond.

Use the or keys to scroll through the range or enter directly from the number keys
on the annunciator.
Then press .
Smoke Detector Sensitivity
All detectors in the zone will respond as programmed in this menu location.
Note: Automatic drift compensation is always in effect for all detectors. See Section 8.4.10 for information about
how to check if a detector is in compliance.
6. Use the or keys to scroll through the range or enter directly from the number keys
on the annunciator.
7. Then press .
IMPORTANT!
Drift compensation is automatic for all smoke detectors (photoelectric and
ionization). The feature is always in effect, no programming is required. See Section
8.4.10 for information about how to check if a detector is in UL compliance.

Choices Comments
Photoelectric
Smoke Detector
Low (3.5% obscurity) If the day/night sensitivity option is selected, you can have different
sensitivity settings during the day and at night. You can determine the
days of the week that Day/Night Sensitivity will automatically adjust.
You can also designate specific days as Holidays. Holiday and weekend
days will use night sensitivity for the entire day
Medium
(2.5% obscurity)
High
(1.5% obscurity)
Photoelectric duct
Detector
See Note. Low, Medium and High settings have no effect for photoelectric duct
detectors. Photoelectric duct detector sensitivity is always 1.1% per foot.
Day and night settings also have no effect on these detectors.
Ionization Smoke
Detector
See Note. Sensitivity for ionization detectors is always 64 MIC (1.1% obscurity per
foot) regardless of Low, Medium or High setting. Day and night settings
also have no effect on these detectors.
Ionization Duct
Detector
See Note. Low, Medium, or High settings have no effect for ionization duct
detectors. Ionization duct detector sensitivity is always 75 MIC (0.8%)
regardless of Low, Medium or High setting. Day and night settings also
have no effect on these detectors.
