Intelligent Detector Functions
Note: For instructions on
selecting Intelligent Detector
Functions, refer to the
AFP-300/AFP-400 Programming
Manual.
Table 7 contains descriptions for intelligent detector functions used with the control
panel.
Table 7 Intelligent Detector Functions
Function Description
Analog Display The control panel reads and displays analog information from the
198 analog detectors. The display shows the percent of the alarm
threshold for each detector.
Sensitivity Adjust Nine selections for manually setting intelligent detector alarm
levels within the UL range. If using Ionization detectors in duct
applications, set Sensitivity Adjust to Level 1.
Day/Night Sensitivity
Operation
You can program the system to automatically force smoke detectors
to minimum sensitivity during the day. Refer to “Time Control
Zones” on page 19.
Maintenance Alert When compensation reaches the limit of the amount of drift
compensation that can be safely applied, the control panel reports a
special trouble condition, per national fire code standards. This
condition also activates if the detector remains at very high or very
low levels for an extended time.
Automatic Test
Operation
The control panel performs an automatic test of each detector every
256 minutes. Failure to meet the test limits causes an AUTO TEST
Fail trouble.
Type Code
Supervision
The control panel monitors hardware device type codes (CPX,
SDX, FDX, LPX, IPX, MMX, and CMX) for each installed device
at regular intervals (an interval can take up to 30 minutes for full
capacity system). If a mismatch of type compared to the program
occurs, the control panel generates a point trouble labelled Invalid
Type.
LED Control
Operation
A global program selection to prevent detector LEDs from blinking
during normal operation. A typical application is a sleeping area
where a blinking light can distract people. As a standard function,
the control panel allows all LEDs to turn on in alarm.
Alarm Verification
and Counter Operation
The control panel performs alarm verification on programmed
CPX, SDX LPX, and IPX intelligent smoke detectors. The
verification time is a global program selection of 0–30 seconds.
Each detector includes a verification counter, which displays the
number of times that a detector entered verification but did not
time-out to alarm. The counter increments to 99 and holds.
