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.

    I'd agree, but the presenter is suggesting the need for DP isolation has gone from the new version. (of the fire standard, BS7671 may still need it....)

    Pretty sure it's still there, maybe I'll check tomorrow, if I'm feeling better had covid jab Monday, not been well since!




    Well had a look at bs5839:1:2017 and it seems that the mention of a double pole isolator has indeed disappeared!
