Entry/Exit Delays

Exit Delay

Exit delay begins immediately after arming the system, and gives you time to leave through the designated exit door without setting off an alarm. A slow beeping will sound throughout the exit delay period, if programmed.

Exit Alarms

Exit Alarm Active

To minimize false alarms sent to the alarm monitoring company, your system may have been programmed for this feature. Ask your installer if Exit Alarm is active for your system.

Whenever you arm the system, the exit delay begins. If an entry/exit door or interior zone is faulted when the exit delay ends (e.g., exit door left open), the system sounds an alarm and starts the entry delay timer. If you disarm the system before the entry delay ends, the alarm sound stops and the message "CA" is displayed on the keypad, along with a zone number indicating the faulted zone. No message is sent to the alarm monitoring company. To clear the exit alarm condition, the open zone must be made re-secured; to clear the display, enter your code plus OFF.

If you do not disarm the system before the entry delay ends, and an entry/exit door or interior zone is still open, the alarm sound continues and an "exit alarm" message is sent to the alarm monitoring company. The message "EA" is displayed on the keypad, along with a zone number indicating the faulted zone. To stop the alarm, the system must be disarmed (your code plus OFF); to clear the display, enter your code plus OFF a second time. An exit alarm also results if an entry/exit door or interior zone is faulted within two minutes after the end of the exit delay.

Entry Delay

Entry Delays give you time to disarm the system when you re-enter through the designated entrance door. You must disarm the system before the entry delay period ends, or an alarm will occur. The keypad beeps during the entry delay period, reminding you to disarm the system. There are two entry delays (if programmed). The first is for your primary entrance and the second can be used for a secondary entrance, where a longer delay is required to walk to the keypad to disarm the system.

You can also arm the system with no entry delay at all by using the

NO DELAY

key when

arming. This can provide greater security while on the premises or while away for extended periods of time. See ARMING THE SYSTEM section for procedure.

See your installer for delay times programmed for your system.

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.
