Contest Brief

I'm seeking an expert in PCB design to create two high-quality circuit boards for conventional alarm systems sirens including Horn and Strobe.


**Requirements:**

-Design one PCB with exclusively through-hole (TH) components.

- Design a second PCB with surface-mount technology (SMT) components or a mix of SMT and TH components. The preference for SMT component size was not specified, so I welcome your recommendation based on your expertise.

-A no less than 90dB preferably 100dB high sound.

- The ability operate with conventional fire alarm systems

- The circuit must operate on from 16-33V at max of 100mA

- PCB should not include any MCUs

- board should not exceed 5cm x 5cm in dimensions

- design should have through holes for securing the board inside the housing

-include 6 through hole 5mm LEDs that flashes with the horns sound
- Include a piezoelectric buzzer that connects through TH + and - points.


- Deliverables include Schematic Design with Gerber files and a Bill of Materials (BOM) for each design, clearly listing all components with specifications in terms of values, names and types and quantities. Components must be available in middle east region preferably Egypt



**Ideal Skills and Experience:**

- Proficiency in PCB design software (e.g., Altium Designer, KiCad, EasyEDA, Eagle)
- Experience with both TH and SMT component layout
- Knowledge of acoustic design principles, specifically relating to alarm systems

The winning freelancer will demonstrate a deep understanding of PCB design principles, especially in compact, high-performance applications like this one. Your suggestions will help ensure the functionality and reliability of the final product.
