to me ,its more about liability and proper testing then anything else. i don't see how one man can test a large building alone. we do mostly commercial work, with many large apartment, housing blds. how do you correctly test all a/v devices in a say, 7 story building? add more say one without a elevator. do you ring horns or evac tone until you are able to get back down 7 story's to silence, confirm point and reset? flip side, you do a silent test, make your way up 7 flights, horns bypassed, trip a point, get back down to panel and another zone had come in while you were off somewhere else in the building with no one at the panel. safety and liability reasons alone to me seem that a true one man test for anything other then a single story account is truly not the way to go....regardless of economical reasons. you say youre a owner or manager, who sends out one guy to do the testing, sometimes in large complexes? my question is when that tech is alone, and something goes wrong while hes no where near the panel, albeit shut down or live whos taken the blame? you as the company or him, as the license holder onsite? we all know its the man onsite saying its what he was told to do......i will say i am pretty surprised that no code has anything written up on this subject. i know i have spoke to several AHJ's and all say i better never catch just one guy testing anything in my jurisdiction. as said before, there's a lot more to testing then just tripping a smoke or pull in most buildings expecting one man to do this, efficiently . safely and effectively is mind boggling. even with panels that provide walk test features, to me doesn't seem like the proper way to test any type of a life safely system. now , i don't do many inspections, i mostly install, service and programming. but when i hear the buildings guys are being asked to test alone it amazes me. and let me ask when you guys have your final tests with the AHJ, do you send one guy for those? explaining to the fire Marshall that he will run to one end of a building, trip a device and return to the panel to give him the description? if not i don't see how a regular inspection is in anyway different.
