Fused Isolators etc

A range of items that are required in the installation of a fire alarm system.

The fire isolator switch provides a secure method of isolating the mains supply feeding a fire system control panel and is crucial for fire system maintenance. The supply can only be isolated by an authorised person, by means of a key lock switch and switching is restricted by key operation. The key is removable in both ON and OFF positions and without the key, a tool is needed to disconnect the power.

Many installers are still unaware that the installation of a fire isolator switch is a legal requirement to ensure all new fire alarm systems in the UK meet the requirements of the BS5839 Part 1 standard.
