Universal Smoke Sensing Technology Vs Typical Ionization / Photoelectric Alarms

Universal Smoke Sensing Technology (USST) Alarm Features:

  • Not your average alarms - responds to both fast flaming and slow smoldering fires - with one sensor, in one alarm.
  • Contains patented microprocessor technology.
  • Respond up to 87% faster to slow smoldering fires.
  • More affordable than dual sensor alarms, and most competitor's stand-alone photoelectric alarms.
  • Can distinguish between cooking smoke or steam and real fire, significantly reducing nuisance alarms.
  • Several options available: combo smoke/co alarms, 10 year battery alarms.

Three Types Of Smoke/Fire Sensors In Today's Alarms

U.S.S.T® IoPhic®

Containing a patented smoke sensing technology. U.S.S.T. alarms are very effective at detecting fast flaming fires and also respond quickest to slow smoldering fires. This sensor type Provides the Maximum Overall Protection and addresses the primary concerns of Fire Service Professionals.


More effective at detecting fast flaming fires - fires which consume combustible materials rapidly and spread quickly. Sources of these fires may include paper burning in a wastebasket, or kitchen grease fires.


More effective at detecting slow smoldering fires - fires which burn for hours before bursting into flame. Sources of these fires may include cigarettes burning in couches or bedding

The power of USI patented Smart Alarm Technology - Virtually Eliminates Nuisance Alarms

Universal Security Instruments created its microprocessor software to virtually eliminate nuisance alarms caused by non-hazardous sources such as every day cooking smoke or steamy showers. Nuisance alarms are the leading reason given for disabled smoke alarms. Almost 50% of deaths attributed to fires were in homes without a functioning smoke alarm. Other branded smoke alarm have used the same sensor technology for years, USI has gone above and beyond to provide a cost effective smoke/fire alarm integrated with the newest microprocessor technology to date.

Why Should I Choose USST Smoke Alarms For My Home?

The National Fire Protection Association has recommended both ionization and photoelectric smoke alarm sensing technologies to be used in the home for optimum response to both fast flaming and slow smoldering fires. Our new Universal Smoke Sensing Technology alarms have been tested to respond to both of these types of fires faster then normal ionization or photoelectric alarms. Every minute counts when it comes to protecting your home and loved ones, make sure you are properly prepared with an brand you can trust.

Where Should I Install My USST Alarms?

Unlike other smoke alarms, Universal Smoke Sensing Technology smoke and fire alarms are ideal for every room in the home. According to the NFPA, smoke alarms should be installed in every sleeping room, outside each separate sleeping area, and on every level of the home.
