Emergency Calling System with LED Display and Sound Alerting Function

A emergency calling button is used around a hospital bed that allows patients to alert a nurse or other hospital staff at the nurse’s station to know the patient’s need. For basic system, has nothing more than a button for patient. When the button is pressed, nurse is alerted by a light or an audible sound at nurse’s station. Now we integrate wireless calling button and wireless receiver host with LED display tube to build a brand new emergency calling system.

Like basic system, this wireless type has ability for alerting nursing staff by sound, light or display rooms and beds’ messages in a terminal. This type has major advantage that is no wiring works while installation and reducing the costs. It’s much more mobile and handy than conventional system.

Our remote control calling system is the hi-tech electronic product which is integrated wireless communication and computer technology. It includes calling button and calling receiver. Each system has one calling receiver and many calling buttons. When there is a calling from a calling button, calling receiver will display corresponding number.

We do some setting of this receiver host.

The First step:

Working mode setting:

Long press 2sec Button 1 of manager transmitter to enter settings mode; Use Button 3 or 4 to choose “Cd8”(Working mode setting) submenu. This display will show”0”, the press Button 3 or 4 to select the working mode.

Suppose we use it in the restaurant. So we select “4” (Hospital mode ). When you choose “4” mode, screen displays number 011 -999 for you to pair up with your calling button, sounds “Dingdong+Room 1-99+No.1 -9 emergency call”. After finish the setting , press button “2″ of manager transmitter to previous menu or quit to standby status.

Note : After finish the function, please power off and restart the host to ensure the function is comfired.

 

The second step :

Calling Transmitter pairing :

You can use calling transmitter control the receiver host, but you need pair them up at first.

Press Button 1 of manager transmitter for 2 sec to enter “Cd7″ submenu. Press Button 3 or 4 select one of the number, paired number must start from “011″ for calling button, and then press “Call” button on the transmitter, the speaker will sound “successful registration” and the display screen turn to next number “012″ automatically. Then you can continue to do the next pairing up to number 999 calling transmitter (hospital mode) if you need. After finish the pairing, press button “2″ of manager transmitter to previous menu or quit to standby status.

Note: 1) long press Button 3 or 4 of manager transmitter to jump the numbers quickly.

2) While the number is paired , the 4 corner LED indicators will be flicker, or not, if the LED indicators are off, it means that the number has no paired transmitter.

3) in hospital mode, this first two digits mean the room number from 01 to 99, the last one digit means the bed number in one room from 1 to 9, press “UP/DOWN” on the receiver to select suitable room and number.

Stick the calling button to wall or desk.

When patient needs emergency call, press the button, it will display “01  1” and sounds “Dingdong room 01 No. 1 emergency call”. It means room 1 bed 1 emergency call.

Wireless Remote Control Two Appliances with Different Voltage in One Receiver

Question from customer:

Can I use the receiver to control a 24 volt circuit on one relay and a 12 volt circuit on the other relay?

 Answer:

   We are glad to recommend the remote control equipment to you on the basis of your requirement. It is model: S2U-DC12 & C-2L. The receiver is S2U-DC12 and the transmitter is C-2L. The working voltage range of relay is AC 110~240V or DC 0~28V. That means you can connect a 12V appliance to and a 24V appliance in the receiver at the same time. Besides, you can also connect two different AC facilities, two different DC facilities or one AC and one DC facilities in it, if the facilities’ working voltage range is AC 110~240V or DC 0~28V.

   For example, you can connect Lights, Motors, Fans, electrically operated Doors / Locks / Windows / Blinds / Cars or Other Appliances with AC110~240V or DC0~28V in the receiver. Then you use the transmitter to meanwhile turn on/off two devices with different voltage by remote control, if the working environment within a reliable distance (100m/300ft theoretically).

  When you press button of transmitter, the receiver can receive the wireless RF signal from it by passing through walls, floors and doors. So the wireless remote control equipment is more convenient and suitable for controlling two appliances with different voltage.

  Here is wireless circuit diagram. You can connect one DC12V appliance to “A & B” terminal of the relay 2 and one DC 24V appliance to “A & B” terminal of the relay 1. Then supply power to receiver, and you can turn on/off the appliances by remote control. By the way, you need to switch on the positive pole and the negative pole in order to normally supply power to the receiver.
