Other Conditions

4-2.4.1

Operating/Storage Temperature Range

Kidde ECS System equipment listed herein is designed to operate within a temperature range
of 32°F to 130°F (0°C to 54°C). The latest version of the flow calculation software program
assumes a temperature of 70°F (21°C). Therefore, the container operating and storage
temperature must be in the range of 60°F to 80°F (16°C to 27°C) for a single unbalanced
system protecting two or more separate hazards. If the container operating/storage
temperature is outside this range, an insufficient quantity of agent may be discharged from
one or more discharge nozzles.
4-2.4.2

Storage Temperature

Kidde ECS System equipment is suitable for storage from 32°F to 130°F (0°C to 54°C).
4-2.4.3

System Operating Pressure

The normal system operating pressure for Kidde ECS System equipment is 360 PSIG at 70°F
(25 bar gauge at 21°C).
4-2.5

Pressure Actuation Limitations

Four modes of pressure actuation of the Kidde ECS System cylinders are available.
Note: When cylinders are all connected to a common manifold, they shall be at the same size
and fill density.
