Hints and tips for servicing

The following sections of this page is where I pin various notes and reminders.

Advent ZXT315 Managers Display Panel

The default password for the panel is 1234.

Memory storage for the log is on the SD card which is formatted as fat32.

When the memory space on the SD card falls below 20mb then warning message gets sent at 10am every morning.

Each event on the system gets logged to a file on the SD card. This log takes the form of "date.txt".

In order to free space on the SD card all of the "date.txt" log files can be deleted. Make sure not to delete the other files there will be 5 files remaining. You may wish the copy the log to another storage location before deleting them.

Procedure:

Power off the display.

Remove card from display and copy the log files to a achieve if you wish.

Then delete the date.txt files from the SD card to free up space.

Insert the SD card back into the display.

Switch the display on.

Method:

I attempted to access the user screen when the SD card was full. This resulted in the display dropping to windows operation system. Unable to to find a way to restart the application here, I tried the power management looking for a restart. All I found was sleep mode. I sent the device to sleep mode.

With the display in sleep mode I removed the SD card. Using a old XP laptop I backed up the SD card. To do this I needed a card reader that windows XP complained about but did in fact read.

I had purchased the card reader to attempt the job with my mobile phone. The phone must support "USB OTG" (Universal Serial Bus - On The Go) for this to work. I inserted the memory card into the reader and the reader into my phones USB 3 port. Using "files" application, I selected the USB card and gave my phone permission to use the SD card. At this point because my phone is android it shows the default android files folders in addition to the ones that were already on the SD card.

I selected all files including the folders android had added, then I deselected the 5 files on the SD card that do not follow the "date.txt" format. Next I deleted the files and checked I only had the 5 required files without any added android folders.

I reinserted the SD card back into the display.

In order to restart the application the display needs power removed and then restored. It is possible to remove all of the displays back plate screws to access power there. However, I traced the cables back to the Main CCU box. Inside the is a network termination board (A00381). There are many connectors with power for various parts of the advent network. The connector I needed is marked "Altera Network".

After removing the connector on the "Altrea Network" port and then replacing it, the managers display came back to life.

Advent XT Fault 0544

This fault keeps ringing in every minute or so. It seems to suggest there is a fault in flat 0544 that is unassigned.

No such flat exists at the site. Seeking advice I was informed this is a long standing fault at the site and told simply to park the fault which will then stop it ringing in. I have done that.

it is puzzling me though!

I searched online to see if there is a common fault causing this but have not yet found any new information.

Pull Cord

This pull cord was reported as faulty and was permanently activated. The client removed the wiring before I arrived. Noting these have normally open contacts and normally closed contact I wonder that maybe the resident interfered with the wiring. The cord is missing anyway so a new unit was ordered.

These appear to be simple switches but apparently I need to use the same manufactures part.

I was given the following details.

Part Number: S00510

Description: Ceiling Pullcord with no LED

Aico 186e

This detector is around 10V to 30V and is on a relay base. It is now obsolete.

Aico recommend a replacement is a Ei 3016 with a relay base. However the relay base they recommend is for a mains voltage input. The Ei 3016 is a mains device.

The 3016 will operate the relay on the base from the Ei186. The issue is it is not going to be powered from the 24 volts supplied from the warden call system. It works but only when a properly charged 9 volt battery is installed!

Aico's solution to use a relay base does not address the operation from a 24 volt system. It simply allows a 240 volt mains detector to supply a signal back to a warden call system from the relay. There is a battery back up version of the base (Ei128RBU), it is a rechargeable but only lasts 2 months without mains.
