Generator Remote Annunciators
Life Safety Code, NFPA 101 2000 edition

All emergency generators up to 1985 have to be concerned with NFPA 99. After 1985, NFPA 110 comes into play. Bothstandards have to be followed. NFPA 110 for Level 1 systems adds features not mentioned in previous standards.

The remote annunciator requirements change again with the 2002 edition.

In order to meet the CMS required NFPA 101, Life Safety Code 2000 edition, the remote annunciator must have the following 12 alarms:

Alarm Standard
Generator operating to supply load 99
Control switch not in auto 110
Low Oil Pressure shutdown 99, 110
Pre-alarm Low Oil Pressure 110
High Engine Temperature shutdown 99, 110
Pre-alarm High Engine Temperature 110
Overcrank shutdown 99, 110
Overspeed shutdown 99, 110
Low Engine Temperature 99, 110
Low Coolant Level 110
Low Fuel Level main tank 99
Battery Charger Failure 99

Note: A remote common alarm is also required. Note (5) from NFPA 110 requires a remote common visual alarm be provided for all control panel mounted visual functions. In addition, Note (5) from NFPA 110 also requires a remote common audiblealarm for all required remote annunciator functions.

NFPA 101, 2003 to 2011 editions



If you need to satisfy a jurisdiction other than CMS, like city, county, or state, you may need to consider a later edition. The following combines editions of NFPA 110, Standard for Emergency and Standby Power Systems from 2002 through 2010. The designation 99 applies only to NFPA 99 Health Care Facilities and need not be present for other applications.

Control switch not in auto 99, 110
Low Oil Pressure shutdown 99, 110 Pre-alarm Low Oil Pressure 99, 110 not in 2010 edition of 110 High Engine Temperature shutdown 99, 110 Pre-alarm High Engine Temperature 99, 110 Overcrank shutdown 99, 110 Overspeed shutdown 99, 110 Low Engine Temperature 99, 110 Set to 20 degrees below the manufacture�s recommendations Low Coolant Level 99, 110 Low Fuel Level main tank 99, 110 NFPA 99, 2005 says 4 hrs Low cranking voltage 99, 110



Note: A remote common alarm is also required. Note (5) from NFPA 110 requires a remote common visual alarm be provided for all control panel mounted visual functions. In addition, Note (5) from NFPA 110 also requires a remote common audible alarm for all required remote annunciator functions.

Additional features may be present; however, the above list is exact. Alarms on this list cannot be substituted and the terminology must be precise or you surveyor may not consider it correct. RPM sensor loss, loss of signal, fuel leak day tank, 80% load, system ready, do you no good.

Be Careful!

Generators and automatic transfer switches as well as their appurtenant devices employ high voltages that can hurt you. Do not attempt to work with this equipment unless you are qualified. Observe all rules and cautions found in the manufacturer�s manuals as well as NFPA 70E, Standard for Electrical Safety in the Workplace.
