Owner's Manual and Quick Start Guide

Protect Your Health
The risks associated with CO exposure increase with time.  With one touch of a button, the Defender CA6150 enables you to monitor the current CO level as low as 10 PPM, highest CO level from 10-999 PPM, and duration of the highest CO level detected.

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 CA6150 is safely secured with a screw through the alarm into its mounting plate, and the two factory preinstalled lithium batteries are non-removable.

Protect Your Investment
Defender warranties the CA6150 for ten years, and that the lithium batteries will power the CO alarm for ten years.
