9100 Won't Exit Programming Mode

[mweetman]

Hi

I have a Scantronic 9100 that has been serviced by a local firm since I moved into my house 14 years ago.

The alarm was working fine untill it was last "serviced", but the engineer said that the panel was now broken & needed replacing.

I was suspicious of this as the panel was working fine before he arrived.

 

Anyway, I was involved with Scantronic on the design on this panel, so I took a look at it.

The unit is stuck in programming mode. I can perform all the programming functions, including walk through & bell tests.

However, when I try to exit programming mode with "99 Enter", i get a low beep & "-" is displayed. Hence the unit appears to be stuck in programming mode. As the unit is wired to the line, I don't want to open it up till I understand what is going on.

 

Any hints as to why "99 Enter" wouldn't work?

 

Thanks....

Tamper(s) or the 20+ yrs old product is knacked

The lid spring on pcb needs stretching a bit as not making proper contact with lid.

As above or the battery which can cause strange faults on these.

 

We still have some of these going and still have a replacement PCB

As above there is an open tamper somewhere try holding the tamper switch down with your finger then exit engineer mode, from past experience the lid tamper can be a bit temperamental on those

Thanks for all the great help!

Sorry for the dumb question, but in this state, will the unit dial out if I open it up? I guess not, but thought I would ask.

Power reset after battery change?

The tamper switch was to blame. Thanks so much to everyone.
