Nurse Call System Code Blue


  • GSM automatic dialler, code blue FORBIX SEMICON



Code blue GSM automatic dialer, introduction

Code blue is an added feature to an existing nurse call system. At FORBIX SEMICON we have devised this innovative solution. Used at hospitals, dispensaries, offices, homes, offices and even factory plants. Most of all, this system ensures that the doctors get an alert immediately in case of any emergency.
The system consists of 3 main components:

1. Calling buttons (panic buttons)
2. Receiver console to display the number the calling buttons
3. The receiver console automatic dialer. This sends missed calls and SMS to registered mobile numbers

On press of a button from a remote controller, the CODE BLUE sequence initiates itself.

Code blue sequence initiation

Following is the set of sequences occur on press of panic button:

First, the calling remote number shows up on the receiver display console at the nurse station
Then, an automatic SMS sent to registered phone numbers (with a predefined message)
A sequence of missed calls is then dialled to the same registered mobile number
This immediately alerts the doctor on duty. The doctor may be anywhere in the building. As a result, the doctor will be able to know about the emergency situation immediately.


At times there may be delay in alert SMS and missed call.
This is because of the network delay.
