What's a 调警? (In a Command Center (指挥中心))
Three possibilities:

1) 调警 as an internal police term

Examples:


... 指令通过光纤迅速传递到消防大队、派出所、交警中队等处警单位，提高了调警速度和准确性。
通过110快速调警处置，成功抓获现行违法犯罪嫌疑人91人、救助群众165人


In this context, it means "dispatch"(like 911 dispatch).

It is rarely used outside of police force. So civilians rarely heard of it and may consider it as a wrong word. 

2） You split the sentence wrong

Examples: 


哈尔滨调警用直升机搜捕三逃犯


It is short for 调用, meaning "make use of". Because 警用直升机(police helicopter) also has a 用 in it, omitting the 用 in 调用 would make the sentence less redundant.

3) Short for 调用警力(transfer police force)

Examples:


采用异地调警的方式分别从虹桥分局....
