We use this product, pretty much plug-n-play.
alarmnet - C The challange with all alarm communication methods is the amount of time that the network (all nodes) can operate on stand-by power.
On the fire side, National Fire Protection Association Standards require up to 60 hours of stand-by power for commerical fire alarm systems.
Early on, with the evolution of networks there were some proven concerns about stand-by times, I haven't heard any of that for some time.
I am also a distributor for this
Internet Monitoring product although I have put none in.
Wireless is the "wave of the future", lately, we install a number of different radio products.
