SCH110DPR alarm is a type of siren used for different warning and alert systems. It is typically used in environments where sound activation is necessary, such as factories, warehouses, and public buildings. It has a minimum sound output of 110 dB and is well-suited for outdoor use. As compared to other kinds of sirens, such as strobe lights, the SCH110DPR offers a distinct advantage in that it is fully waterproof, making it suitable for use in wet or hazardous environments.

The device contains two Horns and one Speaker in a single unit with an important feature that allows it to be operated by switching on one Horn and then by external control via a switch. The SCH110DPR can be used in different applications such as factory alarms, fire alarms, and public address systems. It is particularly effective for locations with high noise levels as it can be triggered even when the ambient noise is above 100 dB.

Application Field of SCH110DPR

• Industrial alarms and signals
• Fire and safety alarms
• High ambient noise warning systems
• Public address systems
• Security systems
• Automation systems
• Emergency alert systems
• Warning systems
• Weather warning systems

Working Principle of SCH110DPR

The SCH110DPR works on the principle of amplification of the original sound signal. This is achieved by transforming the signal into an electrical signal, amplifying it, and then sending it out using either a horn or speaker. Generally, this device operates at a frequency of between 30 Hz and 15 kHz. The amplifier increases the sound pressure level of the sound signal up to 110 dB, ensuring that the warning is heard even in extremely noisy environments.

The SCH110DPR siren comes with a source switching unit which allows the user to control the switch and choose between the two horns. This increases the configuration flexibility, allowing the user to choose the type of horn required depending on the application. The switches can be set up to activate the two horns together, or activated one after the other in a cycle. This feature is particularly useful in public address and emergency alert systems, where the horn can be triggered or silenced in selected areas.

The SCH110DPR siren offers easy installation and is generally made of durable materials to ensure that it is robust and reliable enough to withstand the harsh weather conditions. The device can also be equipped with an optional PIR motion detecting unit to activate the siren when any unauthorized movement is detected.

In conclusion, the SCH110DPR siren is ideal for use in a variety of environments, including industrial, commercial, and public settings. With its robust construction, waterproof capability, and quick and easy installation, this device provides a reliable and effective warning system for a variety of situations. The ability to cycle between two horns also allows users to customize the alert system to fit the specific application.
