"Check" and "Battery" Displays

*Not all systems use wireless sensors.

The word CHECK on the keypad's display, accompanied by a "beeping" at the keypad, indicates a trouble condition in the system.

To silence the beeping for these conditions, press any key.

1.A display of "CHECK" and one or more zone numbers indicates that a problem exists with the displayed zone(s) and requires your attention. Determine if the zone(s) displayed are intact and make them so if they are not. If the problem has been corrected, the display can be cleared if you enter the OFF sequence (security code plus OFF key) twice. If the display persists, CALL FOR SERVICE.

Note: A display of CHECK 70 on Alpha Display keypads indicates that the wiring connection to the external sounder is at fault (opened or shorted), and you should CALL FOR SERVICE. See “BELL FAILURE” on next page. A display of CHECK 90 indicates that RF interference may be impeding the operation of wireless sensors* in the system. See “Rcvr Jam” on next page.

2.If there are wireless sensors* in your system, the CHECK condition may also be caused by some change in the environment that prevents the wireless receiver from receiving messages from a particular sensor. CALL FOR SERVICE if this occurs.

IF YOU CANNOT CORRECT A "CHECK" DISPLAY, CALL FOR SERVICE.

K5309-5V2 specifications

The First Alert K5309-5V2 is an advanced smoke and carbon monoxide detector that offers essential protection for homes and businesses. This device is designed to enhance safety by detecting smoke and harmful carbon monoxide gases promptly, ensuring timely alerts to prevent emergencies.

One of the standout features of the K5309-5V2 is its clever dual sensor technology. This model utilizes both photoelectric and ionization sensors, which means it can effectively detect different types of fires. Photoelectric sensors are particularly efficient at identifying smoldering fires that produce more smoke, while ionization sensors excel at detecting fast-flaming fires. This combination significantly increases the likelihood of early detection, contributing to quicker response times and reducing the risks associated with fire incidents.

The K5309-5V2 also employs an advanced carbon monoxide detection system. Carbon monoxide is a colorless, odorless gas that can be extremely dangerous, and the K5309-5V2 provides precise detection to alert users in case of an elevated CO level. With a loud 85-decibel alarm, users are ensured that they will hear the alarm even from a distance.

Another notable characteristic of this detector is its easy installation process. The K5309-5V2 can be mounted on walls or ceilings and comes with an easy-to-understand user manual that simplifies setup. The device is powered by batteries, ensuring it remains operational even during power outages.

Moreover, First Alert has incorporated a convenient test and silence button that allows users to routinely test the functionality of the alarm and silence false alarms without removing the battery.

The design of the K5309-5V2 is another merit, featuring a sleek and compact profile that blends well with various home interiors. It is also equipped with a battery- saving mode that extends the life of the battery, minimizing the frequency of replacements.

Overall, the First Alert K5309-5V2 smoke and carbon monoxide detector presents a reliable, dual-sensor solution that prioritizes safety and convenience. Its combination of innovative technologies, ease of use, and effective alarm response makes it a valuable addition to any safety system, helping protect what matters most in any environment.
