Trouble Operation; Alarm Operation - Honeywell NOTIFIER SFP-5UD Series Manual

Trouble Operation

The FACP performs the following functions at regular intervals in Normal mode:
 Monitors AC input voltage and battery voltage
 Monitors and reports status option cards and control panel
 Refreshes LCD display and updates time
 Scans control panel keypad for key presses
 Tests memory
 Updates and reads all communications busses (EIA-485, etc.)
 i smoke detectors will be polled for maintenance and freeze conditions on initial entry into Normal mode. Thereafter, each
3
device will be polled every hour for freeze and every four hours for maintenance conditions
NOTE: To ensure that the system is functioning properly, the FACP will perform a freeze check five minutes after the panel is reset,
followed by a maintenance check. If there is no freeze or maintenance condition, the panel will continue to monitor for freeze conditions
every hour and maintenance conditions every four hours.
4.4 Trouble Operation
With no alarms in the system, the detection of a trouble will cause the following:
• The piezo to pulse 1 second On and 1 second Off
• The system Trouble LED to flash one second On and one second Off
• The trouble relay to activate
• TROUBL with device type, adjective/noun, address and trouble description will appear on the LCD display
• The same message, along with the time and date, is sent to the optional printer and the history buffer.
• Communicate the trouble conditions to the Central Station
• Terminate upload or download communications
Note that specific troubles will initiate additional actions; for example, loss of AC power will turn off the AC Power LED, etc.
Input Zone
For Input Zones, the following is a typical message that could appear on the LCD display for a device trouble:
The information displayed in the above example provides the following information:
• First line in display:
– The type of event; in this example OPEN indicating a circuit trouble
– Device type identifier; in this example, PULL STATION indicates a manual device. Other device type identifiers which can be
displayed include SMOKE for Smoke Detector, HEAT for Heat Detector, etc.
• Second line in display:
– <ADJ>; refers to the user programmed adjective descriptor from library list resident in the control panel or custom entry via PC.
– <NOUN>; refers to the user programmed noun descriptor from library list resident in the control panel or custom entry via PC.
• Third line in display indicates Zone and the fault condition. Other possible troubles include:
 OPEN - indicating an open circuit
 DIRTY - maintenance alert indicating that an i
before the performance is compromised
• Fourth line in display:
– Time; the current time in this example is 10:00A which represents 10:00 AM
– Date; the current month, day and year in this example is 06 for June, 09 for the 9th day of the month and 18 for the year 2018
Pressing the Acknowledge/Step or Alarm Silence key will cause the pulsing piezo to silence and the system Trouble LED to change from
flashing to on steady. This block acknowledgment occurs regardless of the number of troubles, alarms and supervisory events active in
the system. When the Acknowledge/Step key is pressed and at least one new alarm or trouble exists in the system, the 'acknowledge'
message is sent to the printer and history file. If the trouble clears, either before or after the Acknowledge/Step key is pressed, the 'clear
trouble' message is sent to the printer and history file.
If all troubles clear and there are no supervisory or fire conditions active in the system, the system returns to normal mode operation and
the System All Normal message is shown on the LCD display and sent to the history and printer files. The auto-restore feature will restore
cleared troubles even if the troubles were never acknowledged. Note that pressing the Alarm Silence key when only troubles exist in the
system will have the same effect as pressing the Acknowledge/Step key except the Alarm Silenced LED will light.

4.5 Alarm Operation

Alarm operation is similar to trouble operation with the following differences:
• The piezo sounder produces a steady output as opposed to a pulsed output
• The Fire Alarm LED flashes 1 second On and 1 second Off
• The LCD displays Alarm along with the device name, type, adjective/noun, associated zones and time/date
