Which component is crucial for protecting appliances from mechanical damage in a fire alarm system?

In a fire alarm system, guards are specifically designed to protect critical components and appliances from mechanical damage. These guards provide a physical barrier around sensitive equipment, mitigating the risk of impact or other forms of damage that could compromise the functionality of the fire alarm system. This is particularly important in environments where equipment may be exposed to physical hazards, ensuring that the fire alarm system remains operational and effective in alerting occupants to danger.

While adaptors, covers, and support brackets each play their roles in the assembly and operation of fire alarm systems, they do not serve the primary function of safeguarding against mechanical damage. Adaptors are mainly used to connect different components, covers can protect against dust and environmental factors but do not necessarily provide a robust physical barrier, and support brackets are important for securing devices but do not offer protection from impacts.
