I'm considering in finally laying down a bit of money on z-wave smoke detectors. We have a fairly large house where we rent a few apartment and studios so it seems pretty wise to get some connected to the system. However, the floors are made out of concrete so there's most likely no way for the controller to get past more than 1 floor.
The question I'm wondering is if the unit (SF812) also functions as a repeater? (below is part of the text from the manual)
From The photoelectric Smoke Detector is a Z-WaveTM enabled device which is fully compatible with any Z-WaveTM enabled network. Z-WaveTM enabled devices displaying the Z-WaveTM logo can also be used with it regardless of the manufacturer, and ours can also be used in other manufacturer’s Z-WaveTM enabled networks. Inclusion of this detector on other manufacturer’s Wireless Controller menu allows remote operation of connected modules when the detector is triggered. Z-Wave node in the system also acts as a repeater, so as to re-transmit the RF signal to ensure that the signal is received by its intended destination by routing the signal around obstacles and radio dead spots.From: ftp.zwaveeurope.com/pub/man/en/EVR/EVR_SF812_in_en.pdf
It only says "Z-Wave node" so I can't say I'm certain if they mean nodes in general or this product.
