Operating and Installation Instructions

Step 4: Hush® Control Feature

The Hush® feature has the capability of temporarily desensitiz- ing the smoke alarm circuit for approximately 10 minutes. This feature is to be used only when a known alarm condition, such as smoke from cooking, activates the alarm. You can put your Smoke/CO Alarm in Hush® mode by pushing the test/reset but- ton. The unit will give a voice message "Hush mode activat- ed." If the smoke is not too dense, the alarm will silence immediately and the green LED light will flash every 2 seconds for approximately 10 minutes. This indicates that the smoke alarm is in a temporarily desensitized condition. Your Smoke/CO Alarm will automatically reset after approximately 10 minutes. When the unit returns to normal operation after being in Hush® mode the alarm will sound if smoke is still pres- ent. The Hush® feature can be used repeatedly until the air has been cleared of the condition causing the alarm. While the unit is in Hush® mode, pushing the test/reset button on the alarm will also end the Hush® period. The unit will give a voice message "Hush mode cancelled."

NOTE: DENSE SMOKE WILL OVERRIDE THE HUSH® CON- TROL FEATURE AND SOUND A CONTINUOUS ALARM.

CAUTION: BEFORE USING THE ALARM HUSH® FEATURE, IDENTIFY THE SOURCE OF THE SMOKE AND BE CERTAIN A SAFE CONDITION EXISTS.

Step 5: Peak Level Memory

if the green LED is blinking once every 16 seconds, the unit has detected a hazardous condition. If the CO sensor has detected a CO level of 100 PPM or higher since last reset, it will be recorded by the Peak Level Memory function. To access the Peak Level Memory press the test/reset button. If a reading of 100 PPM or higher has been recorded the unit will give a voice message "Caution, Carbon Monoxide previously detected." If you’ve been away from home this feature allows you to check if there was a CO reading of 100 PPM, or higher, during your absence. Pushing the test/reset button resets the memory. It’s also reset when the batteries are removed. There is no voice message associated with peak level due to smoke. When the test/reset button is pushed, the unit exhibits a normal PTT if the peak level is due to smoke.

As an essential component of modern home safety systems, this device incorporates advanced technologies to ensure effective monitoring and alerts in case of hazardous conditions.

One of the standout features of the KN-COSMXTR-B is its dual-sensor technology, which combines both ionization and photoelectric sensing capabilities. Ionization sensors are particularly effective at detecting fast-flaming fires, making them ideal for kitchens or areas where cooking occurs. On the other hand, the photoelectric sensor excels at identifying slow-smoldering fires, often caused by burning materials. By integrating both types of sensors, the Kidde KN-COSMXTR-B offers enhanced detection reliability, significantly reducing the chances of false alarms while ensuring timely alerts during emergencies.

Another key characteristic of this alarm is its digital display, which provides real-time information about the levels of carbon monoxide present in the environment. This feature allows users to monitor CO levels accurately, understanding things beyond just standard alarm triggers. The device also includes a peak level memory that stores the highest CO reading, enabling homeowners to take necessary actions if elevated levels are recorded.

The KN-COSMXTR-B is user-friendly, equipped with a voice alarm feature that announces the type of danger detected, whether smoke or carbon monoxide. This vocal alert system is crucial, particularly for those who may struggle to recognize beeping sounds during stressful situations. Additionally, the alarm incorporates a test/reset button, making it easy to check functionality and silence the alarm when necessary.

Another notable aspect of the Kidde KN-COSMXTR-B is its battery backup. The device operates on a 9V battery, ensuring continued functionality even during power outages, which is essential for safety. Moreover, the unit is designed with a sleek and compact profile that blends seamlessly with various home decors while being easy to install, either on the wall or ceiling.

In conclusion, the Kidde KN-COSMXTR-B is an exemplary addition to any home safety setup. Its combination of dual-sensor technology, digital display, voice alerts, and battery backup empowers homeowners with reliable monitoring and peace of mind. Investing in this alarm means prioritizing safety against potentially life-threatening situations, making it a must-have for any household.
