Fire Alarm Panel Electrical Isolation.

Zoomup
Is single pole electrical isolation suggested here even if we are going to prod and poke about inside the fire alarm panel? And, what are the two fuses removed mentioned all about? Is the lecturer confused?


Please see 41.12 onwards.

    Interestingly an unswitched FCU is permitted for isolation purposes (by removing the fuse link) - unless on a TT or IT system.....Table 537.4.
