standard response concealed pendent sprinklersViking Standard Response Concealed Pendent Sprinklers terdiri dari thermosensitive glass
bulb sprayer sprinklers dan sebuah adapter untuk memasang penutup yang tersedia dalam ukuran ½” (12.7 mm) terpasang secara vertikal. Plat penutup disediakan agar dalam pemasangan terlihat lebih rapi sesuai dengan dekorasi dan desain.
Lapisan Electroless Nickel PTFE (ENT)  telah di uji untuk  melindungi instalasi dari kemungkinan munculnya karat sesuai dengan persetujuan  standar UL.

Pemasangan plat penutup dilakukan setelah instalasi terpasang dan dilakukan pengujian. Setelah terpasang plat penutup mudah di lepas dan dipasang kembali, hal ini diperlukan saat melakukan penggantian plafon.
