The output characteristics of the sensing device or the control quantity of the sensing element can be adjusted by extracting an adjusting terminal in addition to a power source terminal, a ground terminal, an output terminal and the like outside a housing containing and protecting an electronic circuit. The distinguishing characteristics are that the fire protection installation is portable and has a modular construction comprising a basic system and a number of customized additional systems, which additional systems comprise different additional units that are adapted to a particular function profile that is set in the actual fire protection installation. The solution is mixed vigorously for a few hours and any excess diethylamine is evaporated. The computing system transmits notification data indicating that the electronic device, the second entity, and the transaction device are located within a specified vicinity of the transaction device reader. Polyisobutylene is a preferred water-insoluble thermoplastic polymer, and hydrogenated wood rosin is a preferred polymer toughening agent.
