4.1 Overview of Detector Bases
The FCP-320/FCH-320 Series detector head is used in one of the following listed detector
bases, which are suitable for both flush-mounted and surface-mounted cable feed. They have

all standard bore patterns.
The detector bases are made from white ABS plastic (color similar to RAL9010) and have a
matte surface finish.
The bases have screw terminals for connection of the detector and its accessories to the fire
panel. Contacts connected with the terminals provide for a secure electrical connection when
