Universal Security Instruments 5304 Hardwired Ionization Smoke and Fire Alarm with Battery Backup

This 120V AC/DC hardwired alarm is suitable for replacement or retrofitting homes with existing USI or Universal brand alarms (with battery drawer). Ionization alarms are more effective at detecting fast flaming fires to help keep your family, home and belongings safe. Fast flaming fires typically consume combustible materials rapidly and spread quickly.

The alarm is interconnectable with up to (24) compatible devices including smoke alarms, carbon monoxide alarms, heat detectors and relays. When one alarm activates, interconnected alarms sound throughout the home, providing additional time to escape safely. Other features include single silence/test button, loud 85 dB alarm, and two tamper resistant locking features to secure both battery and alarm. Comes with a 3-year limited warranty.

  • Hardwired alarm with 9-volt super heavy-duty battery backup
  • Quick Find feature to easily locate the alarm that first detected the threat in an interconnected system
  • 2 LEDs indicate smoke/fire and power
  • Front-loading battery drawer for quick battery replacements
  • Tamper Resistant locking feature

Exceeds Industry Standards for Safety

This alarm is suitable for installation in houses, apartments, dormitory and manufactured housing and provides early warning of smoke and fire. For maximum protection, install an alarm inside every bedroom, outside every sleeping area and on every level of the dwelling.

The alarm exceeds industry standards, and is listed by Underwriters Laboratory to Standard UL217 and is California State Fire Marshal approved. Universal Security Instruments—Always Working To Protect Your Family.

About Nuisance Alarms

In a survey by the NFPA, smoke alarms sounded in only half of the home fires reported to U.S. fire departments, and almost two-thirds of home fire deaths resulted from fires in homes with no smoke alarms or no working smoke alarms. This goes to show that having a disabled smoke alarm is as potentially dangerous as not having one. USI alarms provide superior nuisance alarm protection to prevent these accidents from occurring.
