AC Hardwired Interconnected

• Sealed 3V Lithium Battery Backup - 10-year* tamper proof battery eliminates need for battery replacement. Alerts user to replace alarm after 10 years of operation.
• Voice Warning - Warns of hazard by announcing “Fire!” or “Warning, Carbon Monoxide.”
• Intelligent Sensor Technology - Reduces nuisance alarms and offers fast response to real fires.
• Test/Hush Button Functions - A single button that tests alarm circuitry and temporarily silences nuisance alarms.
• Two LED Display - Red LED indicates alarm mode, Green LED indicates AC power is present.
• Peak Level Memory - Alerts user when the unit has detected CO concentrations of 100ppm or higher.

• Ionization Sensing Technology
• Sealed-In 10-Year* Lithium Battery Backup
• Hush® Button
• Alarm Memory Indicator
• 360° Mounting Plate with Tamper Resistance
• 2 LED Indicators

• Front battery pull tab allows battery activation without removing alarm from mounting bracket
• Large mounting base makes mounting easier, protects surface paint from dirt and covers imperfections
• Pre-stripped wiring harness with easy-off cap does not require stripper tool. Tinned strands increase conductivity and wire nut grip

• Large centrally located Test/Hush® alarm control button
• Dust cover protects sensor from contaminates during construction, reducing nuisance alarms

• Easy access front-loading battery door
• Battery backup provides protection in case of power failure
• Interconnectable with up to 24 devices (of which 18 can be initiating) including smoke, CO and heat alarms

Easy Installation

• Front battery pull tab allows battery activation without removing alarm from mounting bracket
• Large mounting base makes mounting easier, protects surface paint from dirt and covers imperfections
• Pre-stripped wiring harness with easy off cap does not require stripper tool. Tinned strands increase conductivity and wire nut grip

Fewer Callbacks

• One button design for easy operation and less confusion. Operates Smart Hush™ and alarm test
• Battery run down protection will shut down alarm memory when AC power is not present, reducing low battery chirp
• Dust cover protects sensor from contaminates during construction reducing nuisance alarms

User-Friendly Features

• Tamper resist locking feature deters alarm theft.
• Alarm memory flashes red LED indicating which unit was the initiating alarm in interconnected system
• Interconnectable with up to 24 devices (of  which 18 can be initiating) including smoke, CO and heat alarms       

• AC-Wire with battery backup Powered by home's electricity in order to provide continuous protection. An included 9V battery protects during short-term power outages.
• Front-Loading Battery Speeds up replacement by eliminating the need to remove the unit from the ceiling or wall.
• Unique Battery Door Design Will not close if battery is not installed properly.
• Voice Warning Supplements warning from the traditional 85-decibel alarm by clearly stating the danger present, fire or carbon monoxide.
• Photoelectric Smoke Sensor May detect visible fire particles associated with slow smoldering fires sooner than an ionization sensor.
• Electrochemical CO Sensor Provides accurate and continual CO protection during the product's life, remains stable during temperature and humidity changes and resists reactions to household gases that may cause false readings or reduce sensitivity.
• Smart Touch Button One button performs the following functions:
  
  • Activates the Hush® feature to temporarily silence nuisance alarms (will announce Hush mode activated, or Hush mode cancelled.)
  • Simultaneously tests the unit's electronics and verifies proper operation
  • Activates the peak level memory feature (will announce CO previously detected if unit has detected levels of 100 ppm or higher)
  • Resets the unit during a CO alarm (Unit will re-enter alarm within 6 minutes of reset if 70ppm or more of CO is present).
  • Silences a low battery chirp for up to 12 hours
  • Silences the end of life chirp for two days
• Tamper Resistant Unit will lock to mounting bracket and battery door will lock to deter theft or tampering.
• Green LED Will flash every 30 seconds to indicate proper operation.
• Red LED Flashes in conjunction with the alarm sounding.
• End of Life Signal Ten years after initial power, the unit will chirp twice every 30 seconds to indicate the need to immediately replace the alarm.
• Low Battery Signal Will chirp every minute and red LED will flash to indicate low battery condition.
• Interconnectable Will interconnect with up to 24 other devices (18 of which can be initiating) including smoke, CO and heat alarms.
