Abstract:

*****EACH PAPER IS TREATED LIKE A SEPARATE DOCUMENT AND MAY BE VIEWED AND/OR DOWNLOADED THAT WAY***** The need for faster and more intelligent decision making regarding the presence or absence of a fire threat has become acute in the commercial aircraft and telecommunications industries, both of which have been particularly hard-hit by the cessation of halon production. The drive toward earlier detection has as a consequence the possibility of increased rate of nuisance alarms; however, there are no accepted standards against which a fire detection system can be operated to assess its immunity to false alarms. A workshop was held at NIST with the main objective to identify physical sources of nuisance alarms that may plague current and emerging fire detection technologies for telecommunications applications and for aircraft cargo areas, to reach consensus on what test methods are appropriate to evaluate a detection system's immunity to false alarm in the presence of physical nuisance sources, and to recommend actions to develop and/or implement these new test methods. The workshop consisted of a number of invited background talks from representatives of the aircraft and telecommunications industries and government agencies. Among the topics discussed were defining realistic fire threats and simulating them; documenting existing environments; simulating environments that lead to false alarms; determining requirements of the industry with regard to the tolerable rate of nuisance alarms; and examing current operating practices as a means to idenfity opportunities to reduce false alarms.
