Product Description
The Models N252 EC Pendent and Recessed Pendent
Sprinklers are control mode, extended coverage
sprinklers for storage and extra hazard density/area
applications. This includes protection of the storage and
display of Class I through Class IV commodities,
non-expanded Group A Plastics, and non-expanded,
exposed Group A Plastics in retail stores. The Model
N252 EC sprinklers offer maximum coverage areas up to
14 ft by 14 ft (196 ft
provided by standard coverage sprinklers. This offers
the advantage of decreasing the number of required
sprinklers, reducing labor and material costs.
Operation
The Reliable Model N252 Extended Coverage
Pendent and Recessed Pendent Sprinklers utilize a
levered fusible alloy solder link. When the rated
temperature is reached, the solder melts and the two link
halves separate allowing sprinkler to operate and water
to flow.
