A Telecommunicator or Emergency 9-1-1 Calltaker/Dispatcher is a critical part of the emergency response team and is the first point of contact for the citizens of the communities served. An emergency  Telecommunicator is responsible for answering emergency calls on 9-1-1 and 10 digit emergency lines, dispatching police officers and firefighters to calls for service using a Computer Aided Dispatch (CAD) system.



NWCDS uses a Fire & Emergency Medical Dispatch System.  The system is a valuable way to identify & classify different types of fire and medical emergencies by providing pre-arrival and first aid instructions until firefighters & paramedics arrive on the scene of the emergency.

The EMD program is facilitated under the guidance of the Northwest Community Hospital Medical Director and each Telecommunicator providing EMD is licensed with the Illinois Dept. of Public Health.







If you have a Police, Fire or Medical Emergency
dial 9-1-1.


NWCDS utilizes an Enhanced 9-1-1  (E9-1-1) telephone network. In many cases the E9-1-1 system displays the caller’s name, location and phone number. This display is dependent upon whether the person is calling from a landline or cellular phone or the using Voice over Internet Protocol (VoIP).

TEXT TO 9-1-1

Beginning August 18, 2014, AT&T, Sprint, T-Mobile and Verizon customers living in or traveling through the Northwest Central Dispatch System service area may be able to use their mobile phones to send a text message to 911 for emergency help.

It is the first 911 communications center in Illinois to accept text 911 messages, which officials say is especially important for residents with speech or hearing impairments.

Texting 911 should be an option only when calling is not possible. A voice call is still the most efficient way to access emergency services, they say.

Texts should include clear location information with the first message, along with the nature of the emergency. Unlike voice calls, emergency personnel will not be able to determine location, nor will they be able to speak with the person sending the text to quickly ascertain their location. Abbreviations and slang should not be used.

If a text to 911 is not answered in a timely manner, customers should not hesitate to make a voice call to 911.

Commercial Mobile Alert System (CMAS) and Wireless Emergency Alerts (WEA)

The Commercial Mobile Alert System (CMAS) is the system interface to the Wireless Emergency Alerts (WEA) service that wireless carriers have been rolling out across the nation in 2012. CMAS is a partnership between FEMA, the Federal Communications Commission (FCC), and wireless carriers, to enhance public safety.

CMAS allows public safety authorities to send geographically targeted, text-like Wireless Emergency Alerts to the public. WEAs will relay Presidential, AMBER, and Imminent Threat alerts to mobile phones using cell broadcast technology that will not get backlogged during times of emergency when wireless voice and data services are highly congested.

CMAS/WEA complements the existing Emergency Alert System (EAS) which sends warnings to television and radio via broadcast, cable, satellite, and wireline communications pathways.
