The violation was written and i was called in to price a install. Called fire prevention to ask what system would satisfy there violation . No answer , if i were to install a low voltage system it would have to go through them for approval . However if line voltage smokes are used it has to go through isd . They write the violation and when they go back to see if the violation has been corrected they cant say if line voltage smokes satisfies the violation . WHAT THE !
