4-2.5.1 Cylinders Close Coupled Using Pressure From A Master Cylinder; 4-2.5.2 Cylinders Not Close Coupled Using Pressure From A Master Cylinder - Kidde Fire Systems ECS Manual

Design and Installation
4-2.5.1 Cylinders Close Coupled Using Pressure From A Master Cylinder
For cylinders close coupled (reach of one flex hose, max. 30 in) using pressure from one master
HFC-227ea cylinder, a maximum of fourteen slave cylinders close coupled can be actuated
from that one master cylinder, using pressure operated control heads on the slave cylinders.
The slave cylinder operation will be through pilot flexible hoses.

4-2.5.2 Cylinders Not Close Coupled Using Pressure From A Master Cylinder
For cylinders not close coupled using pressure from one master HFC-227ea cylinder, a
maximum of four slave cylinders (maximum five cylinders in a group) can be actuated by that
one master cylinder using pressure operated control heads on the slave cylinders. The slave
cylinder operation will be through a 5/16
having a maximum total length of 100 ft (30.5 m). See Figure 4-6.
