[Scantronic 9751 problem]

I found it on eBay.   It was £60.

 

I was getting a bit desperate cos couldn’t get a new board anywhere, even the manufacturer wouldn’t sell the PCB only.

I could only get it new as a kit with outer case, and a keypad. Wasn’t going to pay that cos I’d already bought a new keypad thinking that was the problem.

 

I suppose I was taking a bit of a gamble that it was fully functional, but there are some honourable people out there.

The system will not let me program the tags.

 I follow the instructions, the last thing is to present the tag to the keypad, l get a double peep but the tag isn’t programmed.

 I’ve even bought new tags and tried the original keypad, which turned out to be OK but to no avail

Thanks but I got it sorted. All voltages were good, so took a gamble on it being a PCB problem.

 I got a 2nd hand PCB & case and luckily I was right.

Just 1 little question -  my proximity tags no longer work. Does the main alarm have to be specific to the proximity tag feature ?

It may just be that the alarm was for sale because that feature stopped working !

Thanks, I haven’t tried that, but I will.

That is why I decided to enlist some superior diagnostic brains !

 

There are a couple of other clues to this puzzle

 

removing the keypad & main box cover did not trigger a tamper alarm.

 I did trigger an alarm by disconnecting the backup battery.

Hi 

I was hoping someone might be able to shed some light on a problem I have just encountered.

3 years ago I did a DIY installation of a 9571 with wireless expander and 1 remote keypad with tag reader.

Everything was fine until a week ago, when the keypad stopped responding to key presses ( I still got a confirmation beep with each press)

The screen alternates between.

 

9571    V5.00

Checking  Bus

 

and the date and time

 

01/01/2005            00.00

 

the time clock would begin counting, but it rarely got to 10 seconds before it again showed

 

9571    V5.00

Checking  Bus

 

these 2 screens alternated constantly for 2 days, before permanently showing

 

9571    V5.00

Checking  Bus

 

I foolishly thought it might be the keypad and I bought a replacement but whatever the problem is it isn’t the keypad as the new keypad display 

shows the same message.

 

does anybody have any ideas ?
