Viceværten ringer til alarmcentralen og tjekker brandsikkerheden.

Viceværten means the caretaker, the building superintendent, or sometimes the janitor/property manager, depending on context.

A vicevært is typically the person who looks after a building or housing complex: repairs, maintenance, safety checks, and practical issues.

Also, vice- here does not mean bad or immoral like English vice. In Danish, it comes from the idea of a deputy or substitute.

The ending -en makes the noun definite: the caretaker rather than a caretaker.

• en vicevært = a caretaker
• viceværten = the caretaker

Danish often adds the definite article to the end of the noun instead of putting a separate word in front, unlike English.

Because the verb at ringe meaning to call/phone normally takes til before the person or place being called.

• ringe til nogen = to call someone
• Viceværten ringer til alarmcentralen = The caretaker calls the emergency call center

Without til, it would sound wrong in standard Danish for this meaning.

Alarmcentralen means the emergency call center, the alarm center, or dispatch/emergency services call center, depending on context.

It is made up of:

• alarm = alarm/emergency
• central = center/station
• -en = the

So:

• en alarmcentral = an alarm center
• alarmcentralen = the alarm center

Because Danish, like German, very often forms compound nouns by writing them as a single word.

So:

• alarm + central → alarmcentral
• brand + sikkerhed → brandsikkerhed

This is completely normal in Danish. Where English might use two words or a hyphen, Danish often uses one long word.

Brandsikkerheden means the fire safety.

It breaks down like this:

• brand = fire
• sikkerhed = safety
• -en = the definite ending

So:

• brandsikkerhed = fire safety
• brandsikkerheden = the fire safety

In this sentence, it probably refers to the fire safety situation, standards, or conditions in a particular building.

No. In Danish, brand here means fire, not brand name.

So:

• brand = fire
• brandsikkerhed = fire safety

This is a very common source of confusion for English speakers.

They are both in the present tense.

• ringer = calls / is calling
• tjekker = checks / is checking

In Danish, the present tense can often translate into English in more than one way depending on context:

• Viceværten ringer til alarmcentralen
  = The caretaker calls the emergency call center or
  = The caretaker is calling the emergency call center

The same applies to tjekker.

The basic pattern is:

• infinitive: at ringe → present: ringer
• infinitive: at tjekke → present: tjekker

For many Danish verbs, the present tense ends in -r.

So:

• at ringe → ringer
• at tjekke → tjekker

This is one of the most common verb patterns in Danish.

Because the subject is the same in both parts of the sentence.

• Viceværten ringer til alarmcentralen og tjekker brandsikkerheden.

The subject viceværten applies to both verbs:

• ringer
• tjekker

English does the same thing:

• The caretaker calls the emergency center and checks the fire safety.

You do not need to repeat he/she/the caretaker unless you want extra emphasis.

Yes, it is a real and very common Danish word. At tjekke means to check.

It is a loanword from English, but it has been adapted to Danish spelling and grammar:

• English: check
• Danish: tjekke

So:

• jeg tjekker = I check / I am checking
• han tjekker = he checks / he is checking

That is the Danish spelling used to represent the sound at the start of English check.

Danish often adapts borrowed words so they fit Danish spelling conventions. So even though the word comes from English, it is written the Danish way: tjekke, not checke.

It could be either. The Danish present tense does both jobs.

Depending on context, the sentence could mean:

• The caretaker calls the emergency center and checks the fire safety.
  (routine, general description, or narrative style)
• The caretaker is calling the emergency center and checking the fire safety.
  (happening now)

You usually need context to know which meaning is intended.

Because the sentence is talking about specific, identifiable things:

• viceværten = the caretaker
• alarmcentralen = the alarm/emergency center
• brandsikkerheden = the fire safety

Danish often uses the definite form when the speaker assumes the listener knows which person or thing is meant, or when it is clear from the situation.

A rough English-friendly guide would be something like:

VEE-suh-vairt-en

But that is only approximate. A few pronunciation notes:

• v is a normal v
• æ is somewhat like the vowel in cat, but not exactly
• the r affects the vowel quality
• final -en is often pronounced quite lightly

The hardest part for English speakers is usually the vowel in vært.

Very roughly:

• ringer ≈ RING-er
• tjekker ≈ CHEK-er

A few notes:

• In real Danish, the endings are usually lighter and less fully pronounced than in careful English.
• tjekker starts with a ch sound like in check.
• ringer has a Danish r, which may sound different from an English r depending on the speaker.

Yes. Depending on context, possible translations include:

• the emergency call center
• the alarm center
• the dispatch center
• emergency services

If this is a learning sentence, the emergency call center is probably the clearest and safest explanation.
