Testing the System (to be conducted weekly)

Entering Test Mode

The TEST

key puts your system into the Test mode, which allows each protection point

to be checked for proper operation. The keypad sounds a single beep every 45 seconds as a reminder that the system is in the Test mode.

Note: An alarm message will not be sent to your alarm monitoring company during the following tests.

Disarm the system and close all protected windows, doors, etc. The “READY” message should be displayed and the green READY indicator (if present on the keypad) should also be lit.

Enter the security code then press TEST

WATCH: All LED display segments will light for 3 seconds.

LISTEN. The external sounder should sound for 2 seconds and then turn off.

If the sounder does not sound, notify your service company.

FAULT ZONES. Open each protected door and window in turn and listen for three beeps from the keypad. Identification of each faulted protection point should appear on the display. The display will clear when the door or window is closed.

Walk in front of any interior motion detectors (if used) and listen for three beeps. The identification of the detector should appear on the display when it is activated, and its voice descriptor will be announced. The display will clear when no motion is detected. Note that if wireless motion detectors are used, there is a 3-minute delay between activations. This is to conserve battery life.

To test all smoke detectors, follow the manufacturer's instructions. The identification of each detector should appear on the display when each is activated.

If a problem is experienced with any protection point (no confirming sounds, no display), notify your service company.

When all protection points have been checked and are intact (closed), there should be no zone identification numbers displayed on the keypad.

Exit Test Mode

When testing is completed, exit the TEST mode by entering your security code and

pressing the

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.
