Kodi DB ingati ndi alamu yamunthu?

M'dziko lamakono, chitetezo chaumwini ndicho chofunikira kwambiri kwa aliyense. Kaya mukuyenda nokha usiku, kupita kumalo osadziwika, kapena kungofuna mtendere wamumtima, kukhala ndi chida chodalirika chodzitetezera ndikofunikira. Apa ndi pamenePersonal Alamu Keychainimabwera, ikukupatsani yankho lokhazikika komanso lamphamvu lokuthandizani kuti mukhale otetezeka muzochitika zilizonse. Limodzi mwamafunso ofala kwambiri pa ma alamu achinsinsi ndi "Kodi ma alarm amunthu amakhala bwanji?" Yankho limasiyanasiyana malinga ndi chitsanzo, koma ambirima alarm amunthukutulutsa mawu pakati pa 120 ndi 130 decibels. Mlingo wa phokoso uwu ndi wofanana ndi phokoso la injini ya jet yomwe ikunyamuka ndipo ndi yokwanira kukopa chidwi ndi kulepheretsa ziwopsezo zomwe zingatheke.

 

Ma alamu makiyi amunthu adapangidwa kuti azifika mosavuta pakafunika. Ndi kukoka kosavuta kapena kukankha batani, siren imatulutsa mawu oboola omwe amatha kuwopseza omwe akuukira ndikuchenjeza anthu omwe ali pafupi zamavuto anu. Chidziwitso chachanguchi chikhoza kukupatsani nthawi yamtengo wapatali yomwe mungafune kuti muthawe ngozi ndikupempha thandizo.

Kuphatikiza pa kumveka kwa ma decibel apamwamba, ma keychains ambiri amunthu amadza ndi zina zowonjezera monga tochi ya LED yomangidwa, zomwe zimawapangitsa kukhala chida chosunthika pazochitika zosiyanasiyana. Kaya mukufufuza makiyi anu mumdima kapena mukufuna kupempha thandizo, zowonjezera izi zitha kukulitsa chitetezo chanu.

Kuphatikiza apo, ma keychains achinsinsi nthawi zambiri amapangidwa ngati zida zotsika komanso zokongola, zomwe zimawapangitsa kukhala osavuta kunyamula ndikuphatikizana ndi moyo wanu watsiku ndi tsiku. Kukula kwawo kophatikizika komanso kupepuka kwawo kumakupatsani mwayi wowaphatikizira ku makiyi anu, chikwama, kapena chikwama chanu, kuwonetsetsa kuti nthawi zonse mumakhala ndi chida chodalirika chodzitetezera m'manja mwanu.

 

Zonsezi, fob yachinsinsi ya alamu ndiyowonjezera pachitetezo chilichonse chamunthu. Phokoso lawo lapamwamba kwambiri la decibel, kusavuta kugwiritsa ntchito, komanso kuchita bwino kumawapangitsa kukhala njira yodzitetezera yothandiza komanso yosavuta. Mwa kuphatikiza makiyi a alamu m'moyo wanu watsiku ndi tsiku, mutha kuchitapo kanthu kuti muwonjezere chitetezo chanu ndi mtendere wamalingaliro.
