2-3.3.6 CABLE HOUSING
A cable housing (Figure 2-28) is required when the suppression system consists of three or
more cylinders and utilizes two cable-operated control heads. The cable housing protects the
interconnecting cable between the two cable-operated control heads and secures the two
heads in a fixed position. The length of the cable housing (see Table 2-6) is determined by the
size of the cylinders used in the suppression system.
