Universal Security Instruments Inc. offers several alarms powered with 10-year, sealed and tamper-proof, lithium Permanent Power batteries for continuous protection (even during power outages) against threats, including carbon monoxide and smoke. All devices with Permanent Power include limited warranties. We’ve listed three of the alarms here.
2-in-1 Photoelectric Smoke & Carbon Monoxide Alarm. The photoelectric technology included in this alarm is effective at detecting slow smoldering fires, and the electrochemical carbon monoxide sensor helps eliminate nuisance alarms. The 10-year permanent power battery is expected to last the life of the alarm.
3-in-1 Smoke, Fire and Carbon Monoxide Smart Alarm. With new patented Universal Smoke Sending Technology, this alarm includes photoelectric and ionization alarms to alert against fast flaming and slow smoldering fires and carbon monoxide. The Permanent Power battery eliminates low-battery chirps and saves money over the life of the alarm.
Carbon Monoxide Smart Alarm. This alarm comes with a 10-year sealed battery and a display screen that is easy to read with a red LED light indicator and microprocessor intelligence. It can be wall-mounted or placed on a tabletop.
