How to reprogram address dip switchs on call point L722 system

0
1 comments:
Mr. Anderson
February 28, 2025

To reprogram the address DIP switches on an Intercall 600 call point L722 system:

1. Locate the DIP Switches – The DIP switches are on the call point and are used to set the device address.

2. Check the Current Address – If the wrong address is displayed, verify the current DIP switch settings.

3. Adjust the DIP Switches – Set the switches according to the required address following the programming sheet.

4. Verify Settings – Ensure the new address does not conflict with other devices.

5. Test the Call Point – Activate the call point and check if the correct address appears on the display.

6. Download Text from PSU (if needed) – If no text appears for the address, download the text from the power supply unit.

7. Check for Faults – If the issue persists, inspect for faulty DIP switches or wiring issues.

If the call point still does not function correctly, consider replacing the faulty components.

  • Page 4: Introduction To Intercall

    Indeed the Intercall 600 system is the best selling nursecall system within the UK Since the introduction of Intercall in 1988, we have made people aware that there can be a more flexible, more efficient, more effective way of using nursecall than ever before This leaflet covers our two most advanced addressable call systems, the Intercall 600 and the Intercall 700.

  • Page 5: Guide To Intercall 600

    The INTERCALL 600 is our most popular addressable call system, coupling flexibility with ease of use, it provides a complete solution that out performs practically all other systems available today. Being an addressable system, it requires only one two core connection to network devices and operates at 12voltsDC. The room descriptions may be programmed using a PC compatible laptop computer or similar which can be programmed on or off site as required.

  • Page 6: Guide To Intercall 700

    The INTERCALL 700 is the latest innovation in the Intercall range of advanced call systems. The system boasts all the features of the Intercall 600 system together with hands free two way speech facilities between all audio units. All room call points have an integral infra red receiver which allows a call to be generated away from the call point without the need for trailing wires.
  • Page 7 All INTERCALL systems can be enhanced with the use of accessories which allows the system to be used by patients with virtually any level of disability. The following list details a few of the most popular accessories with their application and part numbers. In addition to the standard range of accessories, we also manufacture bespoke accessories to suit a particular requirement, please contact your supplier for more information.

    With the INTERCALL system, the zoning is configured and controlled by the display units.

When a system is zoned, we must concentrate on the call point addresses and disregard the text that is associated to that address as this will need to be re-programmed when the system is commissioned.
