OPERATION FD-2 When Power is first switched On to the FD-2 Fume Detection & alarm system, there will be a short WAIT delay while the sensors warm-up to operating temperature. The SAFE LED will illuminate when the system is operational, and detects a safe fume level at both sensors. Pressing either FAN On/Off switch will turn that Blower Fan On or Off manually. If Fumes are detected that blower fan will turn on automatically to clear the fumes. FAN ON LEDs illuminate.

If fumes are detected, (SENSOR 1) or (SENSOR 2) status will Flash to identify its source. The audible and visual alarms will latch On & that Blower Fan will be latched On.

ISOL To acknowledge & silence the alarm, press the ISOL/RESET switch once, ISOL LED illuminates. To reset the alarm latches and return system to normal, press the ISOL/RESET switch again.
FAULT The fume sensing circuits are both continuously monitored for faults. If a fault develops in a fume sensor, or the sensor wiring, the appropriate FAULT status will illuminate, accompanied by a steady fault tone.

TEST Pressing the TEST switch starts a test sequence to test all alarm and fault monitoring functions, including alarm latches and fan On latches plus isolate and reset functions.

FUME SENSOR ASSEMBLIES. In a petrol fume type installation with heavier than air fumes, sensors should be mounted at low level near risk area ie near engines and fuel tanks.
Do not mount in wet area of bilge as water will damage sensor. If used to detect fumes of lighter-than-air gases such as Methane or battery fumes then the Fume Sensor assemblies should be mounted at a high level where fumes could collect.

The system should be left in the SAFE operating condition. Fans switched manully as required
