The Defender LL6170 is a professional quality, sealed lithium battery powered low level carbon monoxide monitor. Continuously displays CO levels detected of 5 ppm or more. Visual alert signals are automatically activated at 9 ppm, and audible and visual alarm signals at 15 ppm. Secure mounting system and non-removable batteries.

Product Brochure, Quick Start Guide and Owner's Manual

Protect Your Family
Standard carbon monoxide alarms do not automatically display or alarm at CO levels below 30 ppm, and may not be protective enough, especially for sensitive groups.  The Defender LL6170 is designed to provide added protection for young children, pregnant women (and their unborn children), older adults, and persons with medical conditions who may be more vulnerable to lower levels of carbon monoxide.

Protect Your Health
The Defender LL6170 automatically displays the current CO level detected as low as 5 ppm, and a red LED flashes if 9 ppm is detected for 10 minutes.  The CO monitor beeps every minute if 15 ppm is detected for 60 minutes, and every few seconds if 25 ppm is detected for 30 minutes.

Protect Your Safety
Carbon monoxide is invisible and odorless.  CO detectors may be inadvertently removed and disabled by guests or children when an alarm is activated but nothing is seen or smelled.  The Defender LL6170 includes a secure mounting system, and the factory preinstalled lithium batteries are non-removable.

100% Tested
Made in Canada, the Defender LL6170 is 100% tested at eight different carbon monoxide levels during production, and 100% verified by Quality Control.

• Because CO sensors typically lose sensitivity over time, it is recommended that the Defender low level CO monitor be replaced every three years in order to maintain display accuracy.
• The sensor and display accuracy may be affected by environmental conditions and other circumstances beyond manufacturer's control.

• Integral Restraint Secures Alarm with Phillips Screw through Alarm Body into Mounting Plate

100% Tested: Every Defender LL6170 is 100% tested at eight CO levels from 7 ppm to 510 ppm during production, and 100% verified by Quality Control.

Complies with National Healthy Housing Standard: The National Healthy Housing Standard warns that CO present at or above 30 ppm when measured over one hour, or above nine ppm measured over eight hours, should be deemed hazardous. The LL6170 is programmed to activate a visual alert at 9 PPM within 10 minutes of detection, and a visual and audible alarm at 25 PPM within 30 minutes of detection.

NOTE: The UL 2034 Standard for Residential Single and Multiple Station Carbon Monoxide (CO) Alarms does not permit UL listed CO alarms to automatically display or activate an alarm signal at CO levels below 30 PPM.

The Defender LL6170 is designed to provide added protection for young children, pregnant women (and their unborn children), older adults, and persons with medical conditions who may be more vulnerable to lower levels of CO, and is not UL listed.

When installed in residential applications, the Defender LL6170 Low Level CO Monitor is intended to supplement, not replace, a UL listed residential CO alarm, like the Defender CA6150.

The Defender LL6170 is not designed for use in vehicles or unconditioned spaces.
