W2 SA-K7 Acoustic-Optical Alarm Sounder 16-32.5V DC 100dB IP21C Red

The W2 SA-K7 is a high-performance acoustic-optical alarm sounder engineered for integration into fire safety and emergency notification systems. This device provides a dual-action alert mechanism, combining a powerful audible signal with a clear visual indicator to ensure maximum awareness during critical situations. Designed for reliability in commercial and industrial settings, the unit operates efficiently within a voltage range of 16-32.5V DC, making it a versatile component for modern safety infrastructure.

Advantages

The primary benefit of the W2 SA-K7 lies in its dual-signaling capability, which significantly increases the probability of alert recognition in noisy or high-traffic environments. The robust construction ensures consistent performance, while the high-intensity sound output of 100dB provides effective coverage across large areas. Its compact design and wall-mounted configuration allow for seamless installation in various architectural layouts without compromising the aesthetic integrity of the building.

Suitable for

• Fire alarm systems in office buildings
• Emergency signaling in industrial facilities
• Safety notification in commercial warehouses
• Public building evacuation systems

This device is not suitable for outdoor environments or areas exposed to high levels of moisture, dust, or extreme weather conditions, as it carries an IP21C ingress protection rating. It should also not be used in explosive atmospheres or locations requiring specialized explosion-proof equipment.

Key specifications

• Operating voltage: 16-32.5V DC
• Sound output: 100dB
• Ingress protection: IP21C
• Color: Red
• Mounting type: Wall-mounted
• Application: Indoor use

To install the W2 SA-K7, mount the unit securely to a flat, stable wall surface using the provided mounting points. Connect the device to a compatible fire alarm control panel or power supply unit, ensuring the voltage remains within the specified 16-32.5V DC range. Verify that the wiring is correctly terminated according to local electrical safety standards and perform a functional test to confirm both the acoustic and optical signals are operating as intended.

What to consider before purchase

• Verify that the operating voltage of your existing system matches the 16-32.5V DC requirement.
• Ensure the installation location is strictly indoors to comply with the IP21C rating.
• Confirm that the 100dB sound level is appropriate for the intended acoustic environment.

Usage recommendations: Regularly inspect the device for any signs of physical damage or obstruction to the sounder and visual indicator. Conduct periodic maintenance tests to ensure the alarm remains fully operational and that the signal is clearly audible and visible throughout the designated coverage area.
