The Universal Security Instruments MP116S Photoelectric Smoke and Fire Smart Alarm provides 10 years of continuous protection against deadly threats in the home. The utilization of Photoelectric Technology allows for increased efficiency in detecting slow smoldering fires. Perfect for new or replacement installations, this maintenance-free alarm is suitable for houses, apartments and mobile homes.

This detector features smart alarm technology to assist in completely eliminating nuisance alarms, a single silence/test button to quiet a non-hazardous alarm and an end-of-service life warning that sounds when it's time to replace the battery (approximately 10-years from activation).

The perfect replacement for existing Universal Security Instruments Alarms, this unit features a large mounting base to cover imperfections in drywall and the option to replace retrofitting applications. The quick deactivation key switches the alarm off and makes the batteries safe for disposal. Once the alarm is deactivated, the tamper resistant feature turns on to prevent deactivated alarms from being reinstalled.

This alarm exceeds industry standards by meeting new laws and legislation. The Universal Security Instruments MP116S Photoelectric Smoke and Fire Smart Alarm is ETL listed to UL Standard UL 217 and is also California State Fire Marshal approved.

USI Electric Hardwired Smoke Alarms offer unparalleled peace of mind and protection for your home and family. A hardwired smoke alarm is powered directly by your home's electrical system. This constant power source ensures that the smoke alarm is always on and ready to detect smoke, providing a level of reliability that standalone battery smoke alarms can't match. Hardwired smoke alarms are also designed to be interconnected, meaning if one smoke or fire alarm in the system is triggered, all connected smoke and fire alarms will sound off simultaneously. This feature is crucial for giving everyone in your home an early warning, no matter where the fire starts.

Installation of a hardwired smoke alarm is a straightforward process, especially when replacing an existing unit. Begin by ensuring the power is completely shut off at the circuit breaker for the area you are working in. After removing the old USI Electric smoke alarm, you can typically use the same mounting bracket and wiring harness for your new USI Electric detector, making the upgrade seamless. The new smoke alarm will connect to the existing wiring (typically a black, white, and red or yellow wire) and then twist securely onto the mounting plate. Always follow the specific instructions provided with your alarm and test the unit by pressing the test button to confirm it is working correctly. If you're installing a new hardwired smoke or fire alarm system, it is recommended to consult a qualified electrician to ensure proper wiring and compliance with local building codes.

A key feature of this USI Electric hardwired smoke alarm is the inclusion of a sealed battery backup. While the alarm's primary power comes from your home's electricity, the battery backup is a vital failsafe in the event of a power outage. Fires can often cause a home's power to fail, and the backup battery ensures that your alarm remains fully operational during these critical moments. A model with a 10-year sealed battery means you can go an entire decade without worrying about replacing batteries or hearing annoying low-battery chirps. This maintenance-free design provides continuous, worry-free protection and significantly reduces the risk of having a non-functional alarm due to a dead battery. It's an essential feature that elevates a hardwired system's reliability, offering a complete and dependable safety solution for your home.
