Since carbon monoxide is present in all fires, having both detection chambers work together in one alarm is a breakthrough in the fire safety industry. When either sensor notices a potential hazard, it will communicate with the other. Depending on what is detected, the alarm will adjust its smoke sensitivity in order to better discriminate between a real hazard and a false one. This constant communication enhances the alarm’s overall performance in all fires, and significantly reduces the potential for a nuisance alarm.
This alarm uses ionization sensing technology. Leading authorities recommend that both ionization and photoelectric smoke alarms be installed to help insure maximum detection of the various types of fires that can occur within the home. Ionization sensing alarms may detect invisible fire particles (associated with fast flaming fires) sooner than photoelectric alarms. Photoelectric sensing alarms may detect visible fire particles (associated with slow smoldering fires) sooner than ionization alarms.
Voice Alarm-Announces the hazard type detected thereby helping to speed up the correct reaction to the hazard detected. Alarm announces “Fire Fire” when a smoke or fire hazard is detected and announces “Warning Carbon Monoxide” when a CO hazard is detected.
Combined Carbon Monoxide and Smoke Alarm-A single unit can be installed where previously, two were needed. Reduces installation time and helps to keep home décor attractive.
Test/Reset Button-Tests alarm circuitry and triggers the voice announcement.
LEDs-Flashing green for normal operation and flashing red for alarm condition.
Low Battery Warning-The unit warns of a low battery condition by announcing “low battery” and by initiating an alarm chirp and activating a flashing red LED.
Battery Powered-Provides protection even during power outages when many fire and carbon monoxide incidents occur.
Battery Safeguard-The battery door will not close unless the batteries are properly installed.
Hush® Feature-Temporarily silences nuisance alarms.
