Depo teslim formu yangın algılama sistemini de gösteriyor.

Here, -u is not the accusative. In teslim formu, it is the ending used in an indefinite noun compound.

So:

• teslim = delivery / handover
• formu = its form / form of

Together, teslim formu means delivery form or handover form.

In Turkish, this pattern is very common:

• kimlik kartı = identity card
• telefon numarası = phone number
• teslim formu = delivery form

So in this sentence, Depo teslim formu is the subject, not the object.

The easiest way to read it is as:

[depo] [teslim formu]

First:

• teslim formu = delivery form

Then:

• depo teslim formu = warehouse/depot delivery form

Turkish often stacks nouns like this. The final noun in the compound gets the compound ending, while earlier nouns simply act as modifiers.

So depo tells you what kind of delivery form it is.

Because yangın algılama sistemi is the direct object, and here it is a specific/definite one, Turkish uses the accusative.

Base form:

• yangın algılama sistemi = fire detection system

In the sentence:

• yangın algılama sistemini = the fire detection system

The ending looks like this:

• sistem-i = its system / system of ...
• sistemi-n-i = that specific system as the direct object

That -n- is a buffer consonant that appears before the accusative ending in forms like this.

So sistemini is normal and expected here.

Algılama comes from the verb algılamak, which means to detect or to perceive.

The ending -ma/-me can turn a verb into a verbal noun:

• algılamak = to detect
• algılama = detection / detecting

So:

• yangın = fire
• algılama = detection
• sistemi = system

Together:

• yangın algılama sistemi = fire detection system

This is a very common way to build technical terms in Turkish.

De here means also, too, or as well.

So the sentence says that the form shows the fire detection system in addition to something else.

This de is a separate word, not a suffix.

Compare:

• de = also / too
• -de / -da = in / at / on

For example:

• depoda = in the warehouse
• sistemini de = the system too / also the system

That distinction is very important in Turkish writing.

Because de usually comes right after the word or phrase it applies to.

Here:

• yangın algılama sistemini de gösteriyor
  means
• it also shows the fire detection system

So the thing being added is the fire detection system.

If you moved de, the meaning would shift:

• Depo teslim formu da yangın algılama sistemini gösteriyor
  = The warehouse delivery form also shows the fire detection system
  (implying that some other thing shows it too)

So the position of de matters a lot.

Yes, gösteriyor is the -iyor form, which often corresponds to the present continuous.

But in Turkish, this form is also very commonly used for a current general statement, especially in everyday language.

So with things like:

• forms
• maps
• screens
• charts
• documents

Turkish often uses -iyor naturally:

• Harita yolu gösteriyor.
• Tablo sonuçları gösteriyor.
• Form bunu gösteriyor.

A more formal or general alternative could be gösterir, but gösteriyor sounds very natural here.

The neutral order here is very standard:

• Subject: Depo teslim formu
• Object: yangın algılama sistemini de
• Verb: gösteriyor

So the sentence follows normal Turkish SOV order.

But Turkish word order is flexible, and you can move things for emphasis. For example:

• Yangın algılama sistemini de depo teslim formu gösteriyor.

This is still grammatical, but it gives stronger focus to yangın algılama sistemini de.

So the original version is the most neutral and straightforward one.

Yes, depending on context, göstermek can be broader than just visually “show.”

With documents, forms, and lists, it can mean things like:

• shows
• indicates
• displays
• lists
• includes

So if the context is a form containing information, English might translate it in different natural ways, even though the Turkish verb is still göstermek.

That is very normal, and it does not change the grammar of the Turkish sentence.
