The Universal Security Instruments Hardwired MIC1509S 3-in-1 Smoke, Fire and Carbon Monoxide Smart Alarm provides 10 years of continuous protection against three deadly threats within the home. New patented Universal Smoke Sensing Technology offers the benefits of both photoelectric and ionization alarms in one device to protect against fast flaming and slow smoldering fires. This detector also features protection against the silent killer - carbon monoxide - making it a 3-in-1 device. The ideal addition for new or replacement installations, this maintenance-free alarm is suitable for houses, apartments and mobile homes in every room.

This USI Combination Alarm utilizes a sealed back-up battery (included) that 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 battery backup 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. This alarm features microprocessor intelligence to completely eliminate 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 alarm (approximately 10-years from activation).

This USI Alarm conforms to UL217 and UL2034 standards. It is also California State Fire Marshal approved and Federal Housing Authority (FHA) approved to exceed industry standards.

All of the smoke alarms in my house had expired. Several were out of service due to false readings. These were updated direct replacements. The only reason I gave a 4, instead of a 5 on this review is because, one of the models used in my home had updated, and it is more difficult than it should be to cross-reference to a newer model number. New installations wouldn't have that issue.

Nice looking units. Come with very nice paint shield installed that is easy to remove. Only negative is I liked the mounting base on my older USI smoke detectors better. They were stronger and deflected less when tightened and the screws from standard 4 octagon box fit the plate better.

Very easy to install. We had to replace the mounting plate by partially unscrewing 2 screws that did not have to be entirely removed. Next, turn the old plate and replace with the new mounting plate. Screw in the new plate, then plug in and attach the new unit.

I am just installing these today so I cannot comment on false alarms or performance issues. However, I found it easy to replace my old USI hardwired units with the new units - the old and new use the same connector, so I only needed to install the new mounting plates.

It's only been a couple of weeks since I've had it installed, but everything has been good so far. I chose this model because it was compatible with the previous ones locking mechanism. The built-in battery was attractive - I just hope it lasts 10 years as advertised. 10 years without that low-battery chirping!
