Colin one for you, I think?
Just a small query for you with reference to BS5839,2002 section 2 paragraph 3 under the heading of Radio Linked Systems,
“Signal levels and background noise at every point of the system.”
Does this mean that you have to go to each individual head/point and take a reading or you can take the reading from the panel if capable of doing so?
your thoughts on this would be appreciated
-
i take the readings from the control panel per device.
-
Princess I agree that probably you should go to each individual device/point which would be fine in a small location but with a large location with multiple floors, well you see what I mean! And surely you know the system is robust enough because you did it all when the initial survey was done and when the system was commissioned?
I realy dont know what youd know unless youd like to share what you do know, what or where are you a Princess of??
Graeme I thought this might be the better option but apparently not all panels are capable of doing this, but if the panel is capable then this means that you would have to have a lap top in your possession, down load the info, and then transfer to your log book !
-
Spidge-
can you not use an on board printer on the panel you use?
-
Princess-international Women of Mystery
That is what Spidge is getting at,how to print off signal levels at a service visit.
As for revealing your secret technical knowledge-i won't tell anyone if you post it on here,it will be between you and me..
-
Ah Princess, how can such wisdom come from the mouth of someone with such exquisite legs?
-
Graeme - spokes person for Splidge
Why cant he just write the signal levels down?
Princess-that would be too easy. Engineers like a challenge and besides a print out is more pro and not made up.
-
Princess, Yes we have. As I recall, you had soup, while I had a Spanish omelette.
-
Princess’s and gentlemen, Ive got a pencil somewhere? But as Im not the engineer I wont have to write it down any way.
As for the techy bit why cant the readings be taken from the computer that has the graphics package it could be written into the software, you could do “it” any time you had a glitch with the system, but this doesn’t answer the question “head or panel” not “soup or omelette” as for the legs Princess post a picy please!
As for me having a spokes person "Graeme" or another, I grew out of short trousers a few months ago!! honest, and ive got some legs as well, not bad looking if i do say so myself!!!!;)
-
i too have witnessed the aforementioned limbs of the royal one amongst us, however im not sure that political correctness would allow me to make coment as to whether they are stll quisite or in fact used to be quisite and are now ex-quisite.
i can say however that they do move in mysterious places - having witnessed them at the bugs, however i would not like be seen to be sending the wrong signals, whether uhf or otherwise!

Splidge, she told you already. At the head.
-
Thanks Collin, but it was interesting to see that the measurements are also taken from else wear not just at the head as indicated.
I'd still like to see the picy though! Whats the chances Princess?
-
Collin
Just sprung to mind, as 1 of the principal authors of BS 5839, 2002 said
"It is meant for the guidance of wise men and the blind obedience of fools". could this be true?
-
just being curious but if you are not an Engineer,why do you need to know?
The panel i have used in the past has the facility to call up a device and view it's signal level,head value and battery left as well as RSSI interference levels.
-
work at a place that has radio stuff, just wanted to be sure of the facts because im involved with an upgrade of this system and wanted to know if other means were ok or not?
-
If he said that it must be true. And if the princess sent you a pic her beauty would blind you so much you would never be able to read a signal level again-whether at the head or elsewhere. While in all honesty i think there may be a disparity between what the standard says and what people actually do, if you are doing an upgrade, you probably want to be very confident that the signal strength at each detector is ok. You do not want a load of grief from iffy signal levels causing you to be brought back to deal with nuisance fault signals.
-
i like a signal detector with real strength. makes me feel all secure and comfort blanketed!

i prefer a cuddle
-
I just wish i could get one, (cuddle) any offers?
As I said before though thats fine on a small system, but a large one! on rambling multifloors there should be an easier way than tramping to each head?
As for the beauty well Id risk it if it was worth it!
-
As the princess, whose beauty is well worth the risk, pointed out to you, you need to get a guy to go to each head anyway at some stage.
-
yes i know this now, thats why i asked the question in the first place, because I was'nt sure and if you dont ask then youll never learn and then you wont be able to wind the hierarchy up because they did'nt know ;)
