Title: Fire symbols for Autocad
Post by: Graeme on June 22, 2007, 08:22:24 PM

Hello everyone

Is there a recognised/standard set of symbols for fire alarm detectors etc when transferring a fire detection system design onto Autocad?


thanks you

Conqueror I checked out British Standards online http://www.bsonline.bsi-global.com/search/results/1 I searched for 1630 and found nothing then I searched for 1635 and found the following?

BS 1635:1990  Recommendations for graphic symbols and abbreviations for fire protection drawings  Current  ₤51.00  ₤102.00
BS 1635:1970  Graphical symbols and abbreviations for fire protection drawings  Revised, Withdrawn  ₤51.00  ₤102.00

Two types of symbols are used, based on the fact that different brigades used different versions:
- BS 1635:1990 (e.g. as used by LFB)
- A bastardised version of BS 1635:1970

Ease of understanding is why some brigades continued with the old symbols up until the end of certification last year - the current version would show a smoke head as a squiggle in a square, the variation of the old one the letters DS in a circle

I think it’s about people not liking change but I must confess I prefer the bastardised version. However if we were required to use the current standard we would eventually accept it, I also add to the problem by including both versions on my website.

is there anything wrong with making your own symbols up with a key at the bottom of the page.

For the sake of design work then it's obvious that each device should be different but when drawings are done from scratch for the aid of FF next to the fire control panel then I would have thought if i was an incoming FF the first thing i would look for on the drawings is the zone,then the address of the device in alarm.
Does it make much difference to them if it's a heat or smoke detector in alarm as they have to go to that point anyway?

as long as the drawings give clear indication of zoning and device addresses.

Absolutely Graeme I think what you are suggesting is acceptable. They are for architectural, technical and were very useful for fire certificates when they existed. You could read a fire certificate drawing with out having to revert to the schedule to understand what a symbols meant. However I would imagine despite the British Standard most people still do there own thing.

Thanks

That's what i have been doing for the drawings that go beside the fire panel as i have seen a few from the original design at the panel,in black and white and not easy to find a specific detector quickly.

I use my own coloured symbols that are easy to see but i wanted to check.

thanks again
