Where subject to mechanical damage, an initiating device shall ___________________.

Initiating devices, such as smoke and heat detectors, play a critical role in fire alarm systems by detecting the presence of fire and alerting the system to initiate responses. When these devices are located in areas subject to mechanical damage, it is essential to provide adequate protection to ensure their functionality and reliability.

The need for protection arises because mechanical damage could render these devices ineffective or inoperable, increasing the risk of undetected fires or delayed responses. Protection could come in various forms, such as using enclosures, shields, or placing the devices in locations that are less prone to damage.

By ensuring that initiating devices are protected, we maintain the integrity and reliability of the fire alarm system, adhering to safety codes and standards that emphasize the importance of safeguarding fire detection equipment. This practice assures proper function during emergencies, thereby enhancing overall safety within the environment being protected.
