The Universal Security Instruments Battery Combination Smoke Sensing Smoke and Fire Smart Alarm provides 10 years of continuous protection against deadly threats in the home. Patented Universal Smoke Sensing Technology provides the benefits of both photoelectric and ionization alarms in one device to protect against fast flaming and slow smoldering fires. Perfect for new or replacement installations, this maintenance-free alarm is suitable for every room in houses, apartments and mobile homes. Permanent Power also saves money from battery replacements (up to $38.00 over the 10-year life of the alarm), eliminates annoying low battery chirps and helps the environment by reducing environmental waste from disposed batteries. Perfect for replacement of existing Universal Electric alarms, this unit features a large mounting base to cover imperfections in drywall and offers the option to replace retrofitting applications. Once the alarm is deactivated, the tamper resistant feature turns on to prevent deactivated alarms from being reinstalled. For maximum protection, install an alarm inside every bedroom, outside every sleeping area and on all levels of the dwelling.
