A heat-resistant door device for closing a horizontal coke oven chamber is made of a refractory material, using a material containing silica or a material containing silica and aluminum oxides, in particular. An insulating layer and a magnetic layer including magnetic atoms are provided between any two of the non-magnetic intermediate layers. The communication circuit may be in the form of a passive RF tag that transmits information indicative of bait status and an identifier unique to each pest control device. The method continues with the second device recapturing the data from a plurality of decoded data portions. The bonding layer holds the first and second substrates together thereby forming the secure disc. Two or more base stations may be allocated subframes in a radio frame.
