Linear Heat Detection for Refrigerated Storage Areas

Linear Heat Detection for Refrigerated Storage Areas

A refrigerated storage area, often referred to as a cold store or cool store, is a large refrigerated room or building that is designed for the storage of items in an environment below the outdoor temperature. Typically, refrigerated areas are used to store goods such as fruit, vegetables, seafood and meat. These areas are commonly located near shipping ports that are used for the import/export of produce.

Linear Heat Detection for Grain Silos

Linear Heat Detection for Grain Silos

A silo is a structure for holding bulk materials. In agriculture, silos are used to store grain or fermented feed known as silage. There are many types of silo used for a variety of storage tasks. These vary from tall “tower” silos to horizontal silos and can be made from many different materials including wood, concrete and steel.

Linear Heat Detection Used in Brand New Seattle Tunnel

Linear Heat Detection Used in Brand New Seattle Tunnel

The brand new State Route 99 double-decker tunnel in Seattle opened on the 4th February 2019. The tunnel, which cost upwards of $3.3 billion is expected to fundamentally change the texture of downtown Seattle, both visually and logistically, and was built as a replacement for the ageing Alaskan Way Viaduct.

Using Messenger Wire with Linear Heat Detection

Using Messenger Wire with Linear Heat Detection

Messenger wire is a secondary, steel wire used to add rigidity to cable. It does not carry any signal but is used to add strength to the cable to prevent sagging when running through the air or to make it easier to fish over long distances in commercial installations. In effect, messenger wire provides a backbone so that the cable carrying the signal is not under any strain.

EN54 Linear Heat Approvals

EN54 Linear Heat Approvals

There has recently been some interest in new standards - prEN54 parts 22 and 28 - that will apply specifically to linear heat detection cables. Currently, both these standards are provisional (pr) and cannot be used as a benchmark for performance or quality, or quoted in the specification for the design of a fire alarm system. However, at some point in the future, they will be made mandatory standards that all linear heat detection must adhere to.
