Universal Security

Our smoke alarms utilize ionization and photoelectric sensors to detect both fast-flaming and slow-smoldering fires. Designed with multi-criteria detection technology, these units provide early warnings while minimizing nuisance alerts from cooking or steam. Installation requires no professional expertise.

Protect against invisible carbon monoxide threats with alarms featuring precise electrochemical sensors. These units integrate with home fire safety systems to deliver comprehensive protection. Lithium-free 10-year battery options ensure consistent operation without frequent replacements.

Combination units detect smoke, fire, and carbon monoxide in a single device. Advanced sensing technology identifies multiple hazards simultaneously without compromising performance. Ideal for reducing device clutter while maintaining full home safety coverage.

Step-by-step installation resources help homeowners deploy alarms efficiently. Comprehensive materials include bracket mounting instructions and battery installation guidance. All necessary hardware is included with purchased units.

Our products meet UL 8th edition requirements and national fire safety regulations. Documentation details compliance with federal and state standards for smoke and carbon monoxide detection systems.

Mount the bracket, insert batteries, and secure the alarm. All necessary hardware and instructions are included for DIY installation.

Our multi-criteria detection technology identifies both smoldering and flaming fires faster than single-sensor models.

Our current models focus on core safety functionality without requiring smart home systems.

Replace units every 10 years, or immediately after any activation event or sensor failure.

We offer lithium-free 10-year battery options to avoid hazardous material disposal issues.

I have a USI Electric Smoke & Fire + Carbon Monoxide Alarm. It is a 10 year permanent power/battery backup. It only made it three years. I contacted the company about the warranty and they sent me the manual troubleshooting and resetting. If that doesn't work, they want me to pay to ship the detector back to them along with an $11 check for shipping so they can send me a replacement. So I have to spend $22 in shipping for a replacement that will most likely last 3 out of the 10 years.

These detectors are garbage in my opinion and the customer service is a joke. They found my email in their spam folder even though I filled out the contact info and issue on their website form. Buyer beware! Go with a more reputable company and brand which is also less expensive.

Universal security instruments will not replace a faulty gas/co2 detector. The unit burned. I showed them evidence of the burning on the unit and they refused to replace it.
