[Audible/visual warning]

Six minutes?

At any given time 10% of smoke heads are unlikely to be working!

Six minutes with a blow torch and you can kill every sounder in the system except for one!

[Audible/visual warning]

Hi All,

If one sounder/bell/strobe should get caught in a fire what do we think should be the result?

(i) All of the warning devices should continue to operate except one (the one that is actually on fire)

or

(ii) All of the warning devices should cease to operate except one (the one next to the front door)
