Hiki i ka thermistor hoʻokomo i ka pale palekana palekana ke hoʻololi i nā hōʻailona Pt100 o ʻelua uea a me ʻekolu thermistors uea (RTD) ma nā wahi pōʻino i kahi hōʻailona 1:1 o ka thermistor a hoʻouna iā ia i ka wahi palekana. Hiki ke hoʻonohonoho naʻauao, a hiki ke hoʻonohonoho ʻia ke ʻano maoli o ke kūpaʻa wela ma o ka polokalamu kamepiula. Loaʻa iā ia nā hana o ka alarm breakage uea a ma waho o ka alarm range.
Pono kēia huahana i ka lako mana kūʻokoʻa, me nā mana hoʻokaʻawale, hoʻokomo, a me nā hopena puka.

1. ʻO ka hana kaʻa uila he hana koho, a pono nā mea hoʻohana e kuhikuhi i ke ʻano o ka lako mana ke kau ʻana i kahi kauoha
Hiki ke koho ʻia nā mea hoʻohui kaʻa uila i ka ʻaoʻao 89 o ka "Annex"
2. I ka hoʻokomo ʻana i ʻekolu uea RTD, pono e hōʻoia i ka lōʻihi o nā uea ʻekolu i ka lōʻihi e like me ka hiki.
3. I ka hookomo ana i ka RTD uwea elua, pono e hoopili pokole ia na pahu pale pale 4 a me 2.
