The SC628DJR is a high-performance two-wire audible warning device designed for use in alarm, buzzer, and siren applications. It is designed to alert users to problems and/or danger and to draw attention to safety conditions, emergency alarms, or other critical events.

The SC628DJR utilizes an encased piezo-ceramic emitter to produce an audible signal that is louder, clearer, and more attention-grabbing than traditional audible warning devices. The device can be powered with a standard 12-volt DC power supply and is operated via a simple two-wire connection. It is suitable for use in a wide range of applications, such as home and office fire and smoke alarms, hazardous material warnings, and evacuation signals.

The SC628DJR has an operating temperature range of -40°F to 140°F (-40°C to 60°C) and is moisture and dust-proof, making it suitable for use in hazardous environments. It can be mounted on any surface, including wood, metal, or plastic, and is easy to install with a mounting plate and screws.

The SC628DJR’s working principle is simple. The device uses a piezoelectric element to produce the sound at a frequency of 3 KHz. It is powered using a standard 12-volt DC power supply, and a two-wire connection is used to control the sound. The sound is produced through a combination of air and digital circuitry that amplifies the signal from the piezoelectric element. This makes the sound as loud and clear as possible, allowing it to be heard in even the loudest environments.

The SC628DJR is a reliable and cost-effective solution for auditory warnings in industrial, commercial, and residential applications. It is the perfect choice for emergency or warning situations, as it is easily heard and will alert users when immediate action is needed.
