Document Type and Number:
WIPO Patent Application WO/2012/169802
Kind Code:
A2
Abstract:
The present invention pertains to a composite temperature and smoke alarm device which is capable of augmenting or maximizing safety and productivity, and includes: a smoke detecting unit for detecting smoke using first and second sensors which include a temperature-sensitive, smoke-detecting part arranged between first and second electrodes; a smoke level measuring unit for generating a smoke level measurement signal by comparing a difference between first and second smoke sensing signals, which are outputted from the first and second sensors, respectively, with a set reference signal; and a detection controlling unit for generating a fire alarm signal when the received smoke level measurement signal corresponds to a fire occurrence condition.
