What should NOT be removed from a service label under Texas Fire Marshal's order?

The correct answer is that the "DO NOT REMOVE" notice must not be removed from a service label under the Texas Fire Marshal's order. This notice serves as a crucial element of compliance and communication regarding the service performed on a fire alarm system. It signifies that specific instructions or conditions related to the fire alarm system have been documented and that tampering with this notice could lead to risks regarding the safety and operability of the fire alarm.

This notice is intended to ensure that the integrity of the service record and the status of the fire alarm system are maintained, providing vital information to fire safety officials, maintenance personnel, and building owners about the system's condition and history. Preserving this notice helps in upholding the regulatory framework established by the Texas Fire Marshal, which is essential for the ongoing safety and compliance of fire alarms within buildings.

The other choices, while important, pertain to different aspects of the service label. The inspection date, licensee signature, and service record are crucial for tracking the maintenance history and qualifications of the individuals performing service. However, the "DO NOT REMOVE" notice specifically carries a directive that must be adhered to, emphasizing its importance in maintaining compliance with safety regulations.
