It is acceptable to install additional zones on the engine room detection system control panel to cover other areas where detection is not required by the regulations. A separate system is not needed for the protection of areas outside the engine room.
Non-Coast Guard approved detection equipment must be listed/approved by a nationally recognized testing laboratory such as UL or FM, and installed in accordance with the manufacturers approved design manual. The system may use heat detectors, smoke detectors, or a combination of the two. Optical flame detectors can also be used.
Engine room monitoring systems may be modified by a qualified technician to meet alarm or indication requirements.
HillerSAFE Fire and Bilge Flooding Alarm systems are not acceptable as an engine room fire-detection system aboard commercial towing vessels.
The system certifying entity must have experience in fire detection system design.
Only manufacturer approved system control panel(s) and remote indicator panel(s) such as a control panel repeater can be used on a required fire-detection system. Installation of any unapproved component(s) will void the system approval and certification.
Fire detection systems and equipment can be installed in other spaces as excess equipment. Existing fire detection systems and equipment designated by the owner/operator as excess are must be listed by an independent testing laboratory and is designed, installed, tested and maintained in accordance with the equipment manufacturer’s recommendations and relevant NFPA standard(s).
Items to check:
- As appropriate, an installed fire-detection system or an existing engine room monitoring system with fire-detection capability to detect engine room fires.
- If a fire-detection system is installed, the following components are approved under approval series 161.002 or listed by a NRTL:
- Control panel(s)
- Remote indicator panel(s)
- Fire alarm
- If an existing engine room monitoring system is installed, it uses detectors listed by a NRTL.
- For both fire-detection systems and existing engine room monitoring systems:
- System is installed, tested, and maintained in accordance with the manufacturer's design manual
- System is arranged and installed so a fire in the engine room automatically sets off alarms on:
- A fire detection control panel at the primary operating station.
- On a fire detection control panel or a remote indicator panel at any other operating station(s).
- The control panel includes:
- Power available light
- Audible alarm
- Visual zone indication to identify the location of the fire
- Means to silence the audible alarm while maintaining visual alarms
- Circuit-fault detector test-switch or internal supervision of circuit integrity
- Function Identifying labels for all switches and indicator lights
- System draws power from two sources.
- System serves no other purpose, unless it is an engine room monitoring system.
- System certified by a registered professional engineer, a NICET level IV engineering technician or an authorized classification society.
