What is the primary function of the Air Cleaning Device (ACD)?

What does a RED LIGHT indicate on the ACD Light Indicator?

When does the General Exhaust Fan (GEF) switch to HIGH speed?

What level of CO will trigger the yellow alarm light?

What action should be taken if the GEF motor fan is not functioning?

What should be done if the CVC view panel flashes red?

What does a continuous beeping sound from the electrical UPS indicate?

What is the maximum carbon monoxide (CO) level that can activate the alarm in the Central Ventilation Control (CVC) Box?

How long does the GEF operate at HIGH speed after activation?

What action is not required when CO levels reach 10 ppm?

What does a green light indicate on the system?

What should be done if neither the GREEN nor RED LIGHTS are visible on the ACD?

Which gases are detected by the nitrogen dioxide (NO2) and carbon monoxide (CO) gas sensors?

Air Cleaning Device (ACD)

Features a 3-stage filtering system: pre-filter, primary filter, and gas/odor filter.
Effectively cleans the apparatus bay of gases within 20 minutes of activation.

ACD Light Indicators

GREEN LIGHT: Indicates the system is active (ON position).
RED LIGHT: Signals that the system filter needs changing; the CVC view panel will also flash RED.
If neither light is illuminated, the Station OIC must submit an electronic Facilities Service Request.

General Exhaust Fan (GEF)

Operates primarily in LOW speed, only switching to HIGH speed upon detecting registered gas levels.
When apparatus bay doors are opened and closed, or gas levels exceed set limits, GEF operates in HIGH speed for a minimum of 20 minutes.
To check fan operation, perform a 'paper test'; if paper does not stick to the grill, submit a Facilities Service Request for GEF Repair.

Gas Sensors

Nitrogen Dioxide (NO2) and Carbon Monoxide (CO) gas sensors monitor air quality within the apparatus bay.

Central Ventilation Control (CVC) Box

OFF Position: System is inactive.
ALARM B (Red Box Light): Activates at CO levels of 25 ppm and/or NO2 levels of 2 ppm; no immediate action required as the system clears gases in 20 minutes.
ALARM A (Yellow Box Light): Activates at CO levels of 10 ppm and/or NO2 levels of 0.7 ppm; serves as a precaution, with the system also clearing gases.

CVC View Panel

A flashing RED screen indicates a dirty filter requiring service: "Fan 1 Filter Full."
Immediate submission of a Facilities Service Request is necessary upon encountering a flashing red light.

Electrical UPS/Battery Back-Up

Continuous beeping indicates a low battery; the system should not be turned off.
The Station OIC is responsible for submitting a Facilities Service Request for battery servicing.
