Product Description
The Models N252 EC Pendent and Recessed Pendent
Sprinklers are control mode, extended coverage sprinklers for
storage and non-storage 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
), which is almost twice of that provided
2
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 link reaches the rated tempera-
ture, the solder melts and the two link halves separate al-
lowing sprinkler to operate and water to flow.
