The Universal Security Instruments MDSK300S 2-in-1 Smoke and Fire Smart Alarm provides 10 years of continuous protection against deadly threats in the home. New 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. The patented Rate-of-Rise Feature will differentiate between cooking smoke/steam and real fire. Perfect for new or replacement installations, this maintenance-free alarm is suitable for houses, apartments and mobile homes in every room.
The sealed battery (included) will never have to be replaced throughout the life of the alarm, giving you a decade’s worth in peace of mind even in the event of a power outage. 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.
The perfect replacement for existing USI Detectors, this USI Smoke and Fire Alarm features a large mounting base to cover imperfections in drywall and the option to replace retrofitting applications. The quick activation battery pull tab makes it easy to install while the deactivation key switches the alarm off and makes the alarm safe for disposal. Once the alarm is deactivated, the tamper resistant feature turns on to prevent deactivated alarms from being reinstalled.
This alarm conforms to UL 217 Standards. It has also been approved by the California State Fire Marshal and Federal Housing Authority (FHA) to exceed industry standards. For maximum protection, install an alarm inside every bedroom, outside every sleeping area and on all levels.
