Aid Call – New Control Panels, Old Room Units

Renew your aged Aid Call control panel and keep your existing ATX3000 room units

In about 2010 Aid Call refreshed their wireless nurse call system, introducing the ATX 4000 and ATX 5000 room units. The radio frequency was changed from 173Mhz to a more European friendly 869Mhz. Which had the knock on effect of making the older ATX3000 room units operating on 173Mhz incompatible with the new version of control panels.

The Modular Radio Receiver

Fortunately, when then new 869Mhz equipment was introduced (which was a vast improvement), the upgrade to the control panel was simply replacing the 173MHz radio receiver with one that operated on 869Mhz, along with some clever software modifications (bearing in mind the introduction of RS485 communications).

As a result, the idea is that a new panel can be purchased with a 173MHz radio receiver and can be set up to receive calls from older ATX3000 call points.

If you are in a position where your Aid Call nurse call CP3000, CP3400 or CP5000 display panel requires replacement, there are ways to get these older room units to communicate with new, replacement display panels, extending the life of your older 173Mhx ATX3000 room units.


There is one small caveat here, the ATX3000 room units and control panels must have compatible software. Realistically, this means if you’re going to all this trouble of renewing control panels, you may as well get the latest software in your room units.
This is a fairly straightforward (and inexpensive) job of changing the firmware chips inside the call point and, depending upon your control panel, either replacing the chip & PSU or reprogramming the panel. Firmware version 6.01 is the one, and any ATX3000+ units you may have will be OK and not require an upgrade.
If you do require our help, please don’t hesitate to get in touch.

What does this mean?

This now means that a failed older panel can actually be replaced with a new CP5000 version, which as a result means you can keep your existing room units. If also means that if you wished to slowly convert your system to the new ATX 4000 & ATX5000 room units (these are an improvement don’t forget), then this can also be reasonably easily accomplished.

The aid call nurse call systems have the ability to connect a second, 869MHz radio receiver to a CP5000 display in addition to a 173Mhz receiver, so you can run a hybrid system and slowly convert over from old to new style room units.

We’re happy to have an informal chat about converting your old Aid Call nurse call system.

Although easy to modify the older call units to work with the new systems. It may be beneficial in the long run to replace the room units. Although the older style ATX3000 type of call point is fairly robust, we are now at the stage whereby if they fail, repair is not usually economically viable, especially if you factor in advantages of the newer ATX3000+, the ATX 4000 and the ATX5000.


The older ATX2000 & ATX 3000 did not feature a checksum. From V4 onwards, the checksum was included. Which means is that a corrupted message can be detected by the control panel which considerably reduces the likelihood of  false alarms or “ghost calls” , so there are advantages in having more recent firmware.
The new 869Mhz ATX 4000 and ATX5000 also feature a checksum, but have the additional benefit of two way radio communication. On the ATX4000 the confidence LED will not light up until the CALL signal has been received at the control panel and confirmation sent back to the room unit, lighting up the LED on the ATX4000.
On the ATX5000, instead of an LED, the return confirmation displays the details on the local screen of the ATX5000.
