If an intelligent device is in alarm the AX-CTL-1L, AX-CTL-2 or AX-CTL-4 will perform multiple assessments of the
alarming device to ensure that the alarm condition from the device is valid. The value of the assessment time can
be programmed by the installer during installation. Programmable assessment time fields range from 0 to a
maximum of 10 seconds (0 to 20/30 seconds for Multi-Sensor detectors) from the first report of an alarm condition
to the final validated (assessed) alarm condition. Refer to Front Panel Programming Manual or PC-NeT Field
Configuration Manual for further explanation.
Note: Programmed default values for assessment time:
Detectors: Default 5 seconds. Maximum 10 seconds.
Input Modules: Default 0 seconds. Maximum 10 seconds.
When an intelligent device enters an alarm condition the analog value of the device can be viewed by the panel’s
graphical display. Analog values for alarm are set at a value of 55. A pre-alarm value of 45 is set as a default for all
intelligent devices; this field is programmable and can be set at a lower or higher level. Refer to Front Panel
Programming Manual or PC-NeT Field Configuration Manual for further explanation.
If an intelligent device falls below a minimum analog value the AX-CTL-1L, AX-CTL-2 or AX-CTL-4 AX-CTL base
card will enter a trouble/fault warning (i.e.: “Device Dirty) condition for that specific device. In addition, a device
trouble condition (non device dirty) value is normally set at a value of 8 with a programmable range of 4-20.
In addition to all of the programmable capabilities of the intelligent devices, each device can also be setup for
Special Sensitivity Mode (SSM) operation. In this mode of operation devices can be set to perform different
functionality based on time-of-day/day-of-week (refer to Front Panel Programming Manual or PC-NeT Field
Configuration Manual for further explanation). The AX-CTL-1L, AX-CTL-2 or AX-CTL-4 AX-CTL base card supports
10 independent, 7-day time clocks.
Another feature of the detector, in conjunction with the AX-CTL-1L, AX-CTL-2 or AX-CTL-4 AX-CTL base card, is its
ability to sub-address detector base ancillary functions. Each detector is capable of incorporating, based on optional
base utilization, a remote LED and/or relay. When these options are utilized, the user is capable of sub-addressing
each of these options (remote LED and/or relay) to activate independently of the associated detector.
Detector Functions:
The fire alarm control panel supervises the connection to each intelligent detection device. The following statuses
are monitored and reported as trouble conditions at the panel.
Maintenance Alert (Device Dirty):
Indicates that a detector has reached its limit of compensation in its chamber
sensitivity due to environment contamination. It is now in a state where further
contamination could mean the device is susceptible to false alarms.
Device Type Supervision:
If an incorrect intelligent device type is replaced in a detector base.
Device Added:
If the panel finds a device at an address where no device previously existed.
