Panasonic Smart Home KX-HNS105EW Indoor Siren, Adjustable Noise Output up to 110dB, Flash Warning Light, Dual Tone Alarm, White

Great price and fast service Thanks

I received the item in good working order. The delivery was late by two days. Installed it as part of the Panasonic Smart Home Network within minutes and it has been working fine. In all the tests I conducted through triggering my motion detectors and door/window sensors, the siren sounded immediately. Happy with the purchase.For those who contemplate buying this item for use in countries other than the UK, do note that it does not operate with all Panasonic Smart Home Hub sold in other countries as different radio frequency are in use in different countries. For example, this item can be used in the UK, Hong Kong, Malaysia and Singapore. The operating frequency for this particular model is 1.88 - 1.90 GHz. The Panasonic Smart Home systems sold in the US and in Australia used different operating frequencies and thus this particular model KX-HNS105EW is incompatible there. The different models are differentiated by the alphabets at the end of the model number, i.e. those ending with "EW" are sold in the UK, those ending with HM are sold in Hong Kong, Malaysia and Singapore whereas in Australia, it is "AZW".The reason, I ended up buying the KX-HNS105EW from Amazon UK was because I could not buy the KX-HNS105HM siren in Singapore where I live. The item KX-HNS105HM was not in stock. But after some research and checks, I found that the KX-HNS105EW (sold in UK) is actually the same model sold in Singapore as KX-HNS105HM.

Best alarm system I ever have had
