Key Features of KN-COSM-IB
The Kidde KN-COSM-IB combination alarm boasts several key features designed to enhance safety and user experience. It has a loud 85-decibel alarm that alerts occupants in the event of smoke or carbon monoxide detection. The device utilizes permanent, independent sensors for both smoke and carbon monoxide, ensuring accurate detection of each threat. The smoke alarm takes precedence when both smoke and carbon monoxide are present. The unit is powered by a 120V AC connection with a 9V battery backup, which provides continuous operation during power outages. The alarm features a voice message system that clearly announces the type of danger detected, such as “Fire!” or “Carbon Monoxide!”. Additionally, the KN-COSM-IB incorporates a “Hush” feature, which can temporarily silence nuisance alarms. It also includes a peak level memory that records the highest CO concentration detected. This combination alarm is interconnectable with other Kidde/Nighthawk brand alarms, allowing for synchronized alerts throughout the home. The device also includes a low-battery indicator and a test button to check its functionality.
Installation Guide
Proper installation of the Kidde KN-COSM-IB is crucial for optimal performance. This section provides essential guidelines for selecting suitable locations, handling wiring and interconnection, and executing the mounting procedures, ensuring effective protection against smoke and carbon monoxide.
Recommended Locations for Installation
Kidde Safety advises installing the KN-COSM-IB in several key areas to ensure comprehensive protection. Ideally, place the alarm in the hallway outside of bedrooms to effectively alert sleeping occupants. For multi-story homes, install one alarm on each level, including the basement, to ensure full coverage. Within each sleeping area, place an alarm inside every bedroom or in its immediate vicinity. When installing in a room with a sloped ceiling, the alarm should be placed at or within three feet of the highest point of the ceiling. This will ensure the best detection of smoke. It is important to place detectors where they will be able to effectively detect dangerous conditions. Remember to also install alarms in rooms where appliances that use combustion can be found. These locations will help the alarm detect hazardous conditions early and alert you to act.
Wiring and Interconnection
The Kidde KN-COSM-IB is designed for hardwired installation, requiring connection to a UL-listed junction box. All wiring should adhere to the National Electrical Code (ANSI/NFPA 70), NFPA 72, and any relevant local codes. A qualified electrician should perform all wiring tasks. The KN-COSM-IB can be interconnected with up to 24 Kidde Safety devices, but the system should not exceed the NFPA limit of 12 smoke alarms or 18 total alarms. When determining the number of units on an interconnect line, this combination alarm must be counted as a smoke alarm. It is essential to use compatible Kidde/Nighthawk products for interconnection. This unit is not approved for interconnection with any other brand of detection product. Proper wiring ensures the alarm will receive power, and the interconnection will allow simultaneous alarming throughout the house.
Mounting Procedures
The Kidde KN-COSM-IB alarm is designed to be mounted on either a ceiling or wall and should not be used as a tabletop device. The alarm unit is sealed, and its cover is not removable, so do not attempt to open it. To mount the device, you’ll need to attach the mounting bracket securely to the wall or ceiling. Once the bracket is in place, align the alarm with the bracket and rotate it to lock it into position. It’s crucial to note the date of installation and write the “Replace by” date, ten years from initial power-up, on the provided space on the side of the alarm. This is vital for ensuring the alarm is replaced at the proper time. Two labels are included with the alarm; they provide information on what to do in case of an alarm. Be sure to add the phone number of your emergency service provider in the space provided.
Operation and Troubleshooting
The Kidde KN-COSM-IB uses both audible and visual cues for alarms. It includes a test/reset button and a hush feature. Understanding the alarm signals is crucial for proper operation and knowing how to respond in emergency situations.
Understanding Alarm Signals
The Kidde KN-COSM-IB employs a distinct alarm pattern to differentiate between smoke and carbon monoxide detection. A smoke alarm is indicated by a series of three long beeps followed by a voice message stating “Fire! Fire!”. This pattern will continue until the smoke dissipates. The red LED will also flash rapidly during a smoke alarm event. A carbon monoxide alarm, on the other hand, is signaled by four short beeps, followed by a voice message saying “Warning! Carbon Monoxide!”. This sequence will repeat until the CO level decreases or the unit is reset. Additionally, the red LED flashes during a CO alarm. The device prioritizes smoke detection, so in the event of both being present, the smoke alarm will be activated. The unit also features a low battery warning, which is indicated by a single chirp and the voice message “Low Battery” every minute. Furthermore, a memory feature is included, which will cause the LED to flash rapidly if an alarm occurred even if the condition has cleared; this memory can be cleared using the reset button. It’s crucial to familiarize yourself with these signals to respond effectively.
Hush and Reset Functionality
The Kidde KN-COSM-IB features a convenient “Hush” mode designed to temporarily silence nuisance alarms caused by cooking or other non-emergency events. By pressing the test/hush button during a smoke alarm, the unit will enter “Hush” mode, indicated by a voice message saying “Hush Mode Activated.” During this period, the alarm is desensitized and will not sound for minor smoke levels for about 10 minutes. If the smoke continues or becomes more intense, the unit will automatically exit “Hush” mode and resume normal operation, with the voice message saying “Hush Mode Cancelled,” and the alarm will sound. The “Hush” feature is only for smoke alarms and does not apply to carbon monoxide alarms. For CO alarms, pressing the test/reset button will silence the alarm, but the alarm will reactivate within 200 seconds if the CO condition persists. The reset button will also clear the alarm memory. It is crucial to identify the source of the alarm before using the hush feature, and ensure a safe condition before silencing the alarm.
Maintenance and Replacement
Maintaining the Kidde KN-COSM-IB is crucial for ensuring its proper functionality. Regularly test the alarm by pressing the test button to verify the alarm sound and voice alerts. Replace the 9V battery backup annually, or immediately when the low battery chirp is heard. The unit is sealed, therefore, the cover is not removable, and cleaning should only be done with a vacuum or dry cloth. The alarm has a limited lifespan and should be replaced every seven to ten years, depending on the model. Note the “Replace by date” on the side of the unit, or add the date using a permanent marker 10 years from initial power up. When replacing the unit, dispose of it responsibly according to local regulations. It is essential to check the alarm regularly to ensure it is functioning correctly, and not just when the low battery chirp occurs. Always refer to the specific user manual for detailed instructions.
