Taking Care of Your System

Silencing Low

Battery Warning

Tones at the

Keypad

The components of your security system are designed to be as maintenance-free as possible. However, to make sure that your system is in reliable working condition, do the following:

1.Test your system weekly.

2.Test your system after any alarm occurs.

You can silence the keypad’s warning tones by pressing the OFF key, but the keypad's low battery message display will remain on as a reminder that you have a low battery condition in one or more of your wireless sensors. When you replace the weak battery with a fresh one, the sensor sends a "good battery" signal to the control as soon as the sensor is activated (opening/closing of door, window, etc.), causing the low battery display to turn off. If the sensor is not activated, the display will automatically clear within approximately 1 hour.

Replacing

Batteries in

Wireless Sensors

Wireless sensors may not have been used in your security system

IMPORTANT:

Use only batteries recommended by your installer as replacement.

Each wireless sensor in your system has a 9-volt or 3-volt battery. The system detects a low battery in wireless sensors, including smoke detectors, the personal emergency transmitter, and the portable wireless keypad and displays a low battery message*. (A low battery in a portable wireless keypad is detected as soon as one of its keys is pressed, and displayed as 00.). Battery-operated smoke detectors with a low battery also emit a single "chirp" sound approximately once every 20–30 seconds.

Alkaline batteries provide a minimum of 1 year of operation, and in most units and applications, provide 2–4 years of service. 3-volt lithium batteries provide up to 4 or more years of operation. Actual battery life will depend on the environment in which the sensor is used, the number of signals that the transmitter in the sensor has had to send, and the specific type of sensor. Factors such as humidity, high or low temperatures or large swings in temperature, may all lead to the reduction of actual battery life in an installation.

*The low battery message comes on as a warning that battery replacement in indicated sensor(s) is due within 30 days. In the meantime, a sensor causing a low battery indication is still fully operational.

Routine Care • Treat the components of your security system as you would any other electrical equipment. Do not slam sensor-protected doors or windows.

•Keep dust from accumulating on the keypad and all protective sensors, particularly on motion sensors and smoke detectors.

•The keypad and sensors should be cleaned carefully with a dry soft cloth. Do not spray water or any other fluid on the units.

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.
