SECTION 3: OPERATING MODES
3.1
Normal Operation
Apply only EXTERNAL 24 volt DC regulated electrical power.
At this time, turn the external power
ON
and check that the Detector
is operating correctly. Verify during initialization that the red LED
continuously blinks ON for about 10 seconds and then blink once
every 10 seconds during Normal Operation.
In Normal Operation, the Detector is ready to detect fires, report
Faults, should any occur, and will have the red LED blinking ON
every 10 seconds. The Analog type Detector will indicate a 4 mA
output current during Normal Operation.
3.2
Alert / Fire Early Warning
During an Alert or Fire Early Warning condition, the Detector will:
•
rapidly blink the red LED continuously.
•
energize the Alert/Early Warning (energize the relay or indicate
a 12 mA output current).
•
record FirePic in non-volatile memory.
•
record the event in the Event History file in non-volatile memory.
3.3
Alarm Condition
During a Fire Alarm condition, the Detector will:
•
turn ON the red LED continuously.
•
Energize the Fire Alarm (energize the relay).
•
record FirePic in non-volatile memory.
•
record the event in the Event History file in non-volatile memory.
3.4
Fault Condition
During a Fault condition, the Detector will:
•
blink the red LED as indicated in Table 1,
•
indicate a fault (de-energize the Fault relay).
•
record the event in the Event History file.
Faults generally occur for the following reasons:
•
a problem has been encountered, such as a dirty Detector
window.
•
failure in the wiring such as a severed cable, loose terminations.
•
the Detector’s internal self-checking reported a hardware failure.
•
power loss at the Detector.
