FEDERAL COMMUNICATIONS COMMISSION (FCC) Part 15 STATEMENT

This equipment has been tested to FCC requirements and has been found acceptable for use. The FCC requires the following statement for your information:

This equipment generates and uses radio frequency energy and if not installed and used properly, that is, in strict accordance with the manufacturer's instructions, may cause interference to radio and television reception. It has been type tested and found to comply with the limits for a Class B computing device in accordance with the specifications in Part 15 of FCC Rules, which are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

•If using an indoor antenna, have a quality outdoor antenna installed.

•Reorient the receiving antenna until interference is reduced or eliminated.

•Move the receiver away from the control/communicator.

•Move the antenna leads away from any wire runs to the control/communicator.

•Plug the control/communicator into a different outlet so that it and the receiver are on different branch circuits.

If necessary, the user should consult the dealer or an experienced radio/television technician for additional suggestions.

The user or installer may find the following booklet prepared by the Federal Communications Commission helpful: "Interference Handbook". This booklet is available from the U.S. Government Printing Office, Washington, DC 20402.

The user shall not make any changes or modifications to the equipment unless authorized by the Installation Instructions or User's Manual. Unauthorized changes or modifications could void the user's authority to operate the equipment.

IN THE EVENT OF TELEPHONE OPERATIONAL PROBLEMS

In the event of telephone operational problems, disconnect the control by removing the plug from the RJ31X (CA38A in Canada) telephone wall jack. We recommend that your certified installer demonstrate disconnecting the phones on installation of the system. Do not disconnect the phone connection inside the control/communicator. Doing so will result in the loss of your phone lines. If the regular phone works correctly after the control/communicator has been disconnected from the phone lines, the control/communicator has a problem and should be returned for repair. If upon disconnection of the control/communicator, there is still a problem on the line, notify the telephone company that they have a problem and request prompt repair service. The user may not under any circumstances (in or out of warranty) attempt any service or repairs to the system. It must be returned to the factory or an authorized service agency for all repairs.

N8891-1 specifications

The First Alert N8891-1 is a technologically advanced smoke and carbon monoxide (CO) alarm that exemplifies safety and efficiency for modern homes. Designed to provide comprehensive protection against two of the most hazardous threats in residential environments, this device is engineered with an array of features that enhance its functionality and user-friendliness.

One of the standout features of the N8891-1 is its dual-sensor technology. This method combines both photoelectric and ionization sensing capabilities, allowing the alarm to effectively detect a wide range of fire types. Photoelectric sensors are particularly effective for smoldering fires, which may produce more smoke and take longer to ignite, while ionization sensors quickly respond to flaming fires. This combination ensures that users receive timely warnings, enhancing safety and increasing the chances of escape.

The First Alert N8891-1 is also equipped with a unique, easy-to-read digital display that provides real-time data about CO levels in the home. This feature is crucial, as carbon monoxide is an odorless and colorless gas that can be extremely harmful, if not fatal. The display not only indicates the current CO level but also provides users with alerts in case of an emergency or when the battery is low.

In addition to its advanced sensing capabilities, the N8891-1 includes a 10-year sealed battery, eliminating the need for frequent battery replacements and ensuring long-lasting performance. This feature provides peace of mind, knowing that the device will remain operational without the hassle of upkeep.

Another important characteristic is the alarm’s ability to interlink with other compatible smoke alarms in the household. When one alarm detects smoke or CO, all linked units will sound off, creating a synchronized response that further enhances safety throughout the home.

Furthermore, the First Alert N8891-1 is designed with user convenience in mind, featuring a single button for both testing the alarm and silencing false alarms, which can often occur when cooking or from other non-threatening sources.

Overall, the First Alert N8891-1 stands out as a reliable and sophisticated choice for those seeking to enhance their home’s safety features with a dual-function smoke and carbon monoxide detector that seamlessly combines advanced technology, ease of use, and sustainability.
