Cheers Mark,

I still have a lot to overcome in this application in that the battery inside the flashing light is also used as a back up in case power fails, to allow the system works. I hope initially to at least cover the charging method then look at any possible additions that could favour.

These system currently are FESA (Fire and Emergency Approved) but must be supported with a wired powered system to maintain current Australian regulations. This is one of the most difficult challenges to overcome as the regulations here are extremely tight. Insurance companies will not cover fire damages if anything is not approved.

I may continue development for the future on various areas of this type of system in the hope to reduce cost but there are a lot of barriers to overcome.

It is a nice challenge and one that i have been looking for ages to carry out. I am going to miss out on the Waveform generator as I have too much other stuff to cover and don't want to overload myself.

This is a great application.

At work we have been replacing smoke alarms on the out stations and these are wired into our monitoring systems.

The new ones have the option of a closed loop (fail to safety) so that any issues with the 12v supply or wiring, we get an alarm.

I'll check with the guys to see where we get them from as they might be a much friendlier option than the $400 items you mentioned.

I'm certain that you have enough knowledge as a user to develop your own, that provides an alerting facility.

Having a single panel that collects and sends the alert out using the Nordic RF units may be an option.

The 'fail to safe' in this system would be regular polling to see if the device is there and working, and both units would alert if not.

I also did an article recently using the wireless power outlets you can buy locally, and drove them from an Arduino and 433Mhz transmitter.
