Adjust the jumpers or switches according to your desired tone before finalizing installation.

4. Operating Instructions

Once properly installed and powered, the QWORK Fire Alarm Strobe Siren Horn will activate its sound and light warnings when triggered by your connected security or fire alarm system. The activation is typically controlled by the system to which it is wired.

• Sound Activation: Upon receiving an alarm signal, the siren will emit the selected tone at a volume of 105dB or higher.
• Light Activation: Simultaneously, the built-in 6 LEDs will flash brightly, providing a visual warning.

Ensure your primary fire alarm control panel or security system is configured to send the appropriate activation signal to the strobe siren horn.
