so basically I need to get my nsi certification in order to provide a full grade 2 system!, I have already been working inline with the BS7671 in terms of cable routing and containment of cabling, and also in line with EN50131 in terms of the alarm designs, and equipment used!. Not only this I keep my own specifications, commissioning records etc and have a full jobs list and document control system in place!, how long would I need to do this over in order to become certified?
I also fill out all the required standard sheets as to NSI, and produce my own cable schedules, and in some cases even do my own detailed wiring diagrams
I also think a quick layout drawing indicating the placement of detectors, control panel, & external sounder is good in order to back up your risk assesment in terms of weak points within the premises and how good the coverage of the system is!
This information alongside the general overall risk to the premises in terms of usage and area also backs up the grade of installation & equipment needed
in my eyes I think the honeywell galaxy 2 is a superb system because I believe that wired & wireless systems both have there own unique benefits, and with a galaxy 2 you have the ability to get the best out of both wireless and wired together!
