Fireboy Control Module and Alarm Panel

The Fireboy gas detection system control module is located on the center dash panel. See Fig.. The alarm panel is located on the overhead consol. It has a green light, a red light, a buzzer, and a sensor. See Fig.. It is located within view from outside of the vehicle. The large green light is continuously illuminated during normal operating conditions. There is also an optional forward-facing alarm panel located at the top center of the windshield for easy viewing from the front of the vehicle. This panel only has the green and red lights. See Fig..

Before entering the vehicle, always verify that the green light is illuminated. If the green light is not illuminated, do not enter the vehicle. Complete the alarm procedure previously outlined.

The control module and the alarm panels meet the California Highway Patrol Title 13-2008 and NFPA 52 2010 requirements. All drivers and technicians using it should be trained regarding the red and green lights, and the audible warning.

The control module, located on the center dash panel, contains the status lights and control buttons for the system. The areas that the sensors monitor are defined as Zone 1 (cab) and Zone 2 (engine compartment). The control module has lights assigned to each zone that will illuminate if a sensor detects a trace level leak (between 20% and 50% LFL), Or a dangerous leak (above 50% LFL), or if a sensor is disconnected or malfunctioning.

• Green: System is functioning properly.

• Amber: If the system detects that either of the sensors has been disconnected or has malfunctioned, an amber light next to the "FAULT" indicator for that zone will illuminate.

• Red: If either sensor detects gas fumes at a concentration greater than 20% (2.5% gas in air by volume), the small red light next to the "DANGER" indicator for that zone will flash. After approximately 15 seconds, the large green light on the alarm panel will switch off, the red light will illuminate, and the buzzer will sound. All alarm indicators will remain on as long as fumes are detected.

The control module also has buttons used to test or reset the control module and silence the buzzer after an alarm.

• TEST: Press the "TEST" button to test the LED and output operation.

• Reset/Silence: If an alarm has been activated, the "RESET/SILENCE" button will silence the buzzer.

See Table. for the functions of all lights and buttons on the control module.
