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 in-
cludes 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
by standard coverage sprinklers. This offers the advantage of
decreasing the number of required sprinklers, reducing labor
and material costs.
Operation

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.
