About this item:
– High sensitivity, accuracy and reliability: Built with a photoelectric sensor and an electrochemical CO sensor that works independently. Notifies you in time when dangerous smoke or dangerous CO concentration is detected, and minimizes false alarms. Provides the ultimate protection against two deadly threats in one unit.
– Multiple functions: due to the warning of malfunction and low battery level, you can easily identify the operating status of the alarm. In test/mute mode, you can test the alarm weekly and mute the alarm when false alarms occur.
– High quality and manual workmanship: this fire retardant PC plastic alarm provides excellent heat resistance and long service life. The flat and compact structure allows smoke or CO detection discreetly.
