During the entry inspection, I discovered that the supplied batteries that were supplied separately in an envelope but not wrapped, did not identify the specifications that were called on to smoke detectors. It was Chinese products, which are intended to be but to lithium batteries. Whether they meet the requirement to provide 10 years each smoke detector with enough power, of course I can not judge. I have therefore asked the supplier to the supporting evidence (report similar to an official body, public authority) or as an alternative to free replacement of batteries of LT. Smoke detectors sticker required specifications or descriptions. One answer I have not yet received. Next, I noticed that the language on the batteries was mostly unreadable on most packages, where the smoke detectors were delivered. It looked as if the place had been aware of this Inforamtion "scratched" or a label was attached, which was then removed prior to shipment of the smoke detector, whereby the information on the packaging was not or hardly legible. Some smoke alarms I have installed each supplied battery. That went smoothly and testing the smoke alarms were working. I installed the smoke detector is not because I have yet wants to wait for the Rückantrwort on my complaint.
