Can anyone help me with fire and burglar alarm systems symbols? We do structural mainly, so do not deal with any so I have no ideal what the symbols look like. The person we receive the hard copy drawings from just placed a joke schedule on the drawings. Any help will be appreciated.

Suggest you contact a supplier. If anything like structural connector
companies they will send you a cd so that the images you use will be
images of their product, and your specs will read "FireStorm a-3657 or
equiv." (totally imaginary spec.) Also warn you to be careful. At least
3 P.E.'s that I personally know of locally got licenses suspended or
censures for sealing drawings with fire equipment and/or electrical
system specs. This was over a period of several years admittedly, but
those are just the ones I know. Keep in mind that a P.E. license is
based upon your field of training and experience. Going outside areas
where you can prove expertise invites problems.

I've done electrical engineering for over 30 years. And the sad fact of the
matter is, there is no 'standard' for electrical symbols (here in Canada at
least). There should be, but the fact of the matter is, there is as many
symbol variations as Heinz has Pickles.
A Heat detector typically is a 1/8" diameter circle with an X in side it.
Then you fill in two 'halfs' and you have your symbol (that typically is a
somewhat consitent symbol). A smoke detector on the other hand can be similar
to a heat detector, except you use a Square instead of a Circle. But then
I've seen smoke detectors a circle that is 1/2 solid.
Manual pull stations are typically a Box with an "F" inside. Gongs are all
over the map again, etc.
Security devices are even more all over the frigging map. Some use symbols,
others use a box with a Number designation.
You might find some decent local Electrical Consultant who would allow you to
use (or look at) their symbols. Bottom line is, you could use what you
wanted, as long as you have a Symbol Schedule which identifies each symbol.
I could send you what I use for what it's worth. I don't mind either way.

It is true that there is no real established use of standard symbols
in the fire alarm idustry. However, there are a set of established
symbols for fire protection work contained in NFPA 170. I have seen a
migration to their sybmols by many in the industry of the last several
years, but agree in my 25+ years of desiging fire alarm systems, I
even have problems getting engineers in my different offices to use
the same set of symbols.
other responses are all true.
I don't do burgler drawings but the fire alarm drawings I have done use
hexagons, squares, and circles ( sometimes with a triangle attached for
a horn on a horn-strobe ) then a letter someone thought appropriate
inside the outline. but a pull station could be a "P" or an "F" or even
an "M" for "manual pull". then when you have a cabinet of some sort, a
rectangle big enough for the text - "FACP" comes to mind.
the only thing I really want to add is that if you are making up
symbols, I like to have all my text a uniform size. so, I make the
outline AROUND the text for the symbol.
and I have become VERY FOND of making the outline a region, giving it an
elevation, and not breaking the wiring around the symbol. then I can
hide lines before I plot. my wire lines represent conduit, and the
editing is much easier when they move or delete device ( or three ).
heads up. if your symbols are blocks you can update them with ease
globally, but you must be thinking when you create them for being on the
wall v.s. on the ceiling for the insertion points.
cheers.
