SPECIAL APPLICATION

When configured at the fire alarm control panel, this detector is capable of op-
erating in a special application mode such that it has a higher sensitivity than 
is normally allowed by UL 268 for areas where early warning is important. In 
this mode, the detector does not comply with the Cooking Nuisance Smoke 
Test. Detectors (Sampling ports) set to the special application mode are not 
suitable for use in areas where cooking appliances may be used. If cooking 
appliances are used within the protected space, a normal application detector 
or normal application mode must be used for that area.
Special application mode is not for general use and the detector may be more 
prone to false alarms if used in unsuitable environments. While no list is 
all-inclusive, some examples of unsuitable environments for special applica-
tion mode are areas with airborne particulate or aerosols including sawing, 
drilling, and grinding operations, textile or agricultural processing, or areas 
with engines that are not vented to the outside. A complete list of aerosol and 
particulate sources is available in the Annex of NFPA 72. 
Suitable environments for special application mode could include early warn-
ing for hospitals, museums, assisted living and other areas that do not have 
airborne particulate or aerosols.
Refer to the fire alarm control panel documentation for information on how to 
configure the detector for special application mode.
