On the whole, this sounds like an orphaned bit of tech: What Happened To Regalsafe? - Members Lounge - Security Installer Community

In all truth, just from the commentary on that forum, it's not going to be very DIY friendly, and even pros appear to have trouble with them. You may be better served to start over with modern hardware.

Yes I have read that thread. In fact I am confident I have read every page on the entire web regarding Regalsafe, hence posting here. I can tell you that the RS40 does have an EEPROM so it ought to be possible to default.
In another long thread, someone else successfully defaulted this model but forum rules didn't allow them to share the method and there are no contact details for the poster.
So you see, knowing it is possible and out of principle, I don't want to replace this unit.
Many thanks for replying and you are most probably correct with your advice.

Smile How to default a JSB Regalsafe RS40 Alarm panel **SOLVED**

Thought I would just post the solution, having scratched my head all day.
The RS40 has a serial EEPROM on the mainboard. It is an ST93C46AB1.
A quick 'google' found the datasheet and I was able to identify the CLOCK and DATA IN pins (pins 2 and 3). Short these together with tweezers and power up. RS40 will boot up in engineer mode allowing me to change the engineer code.
It's so easy when you know how, although the entire unit had to be dismantled to gain access to the EEPROM.

Cheers,

Doc

Good of you to report it back. Some of these obscure, or old, brand; non-North America systems can be difficult to find any useful info about.

Have fun with it...
