Compliance in this trade is not something a firm keeps in a filing cabinet. It is attached to the equipment, where an inspector, an owner, or the next technician can read it. That starts with the equipment itself: Insurance Code § 6002.251 says a detection or alarm device, alarm system, or item of monitoring equipment intended to detect or give alarm of fire may not be sold, offered for sale, leased, installed, or used to monitor property in Texas unless it carries a label of approval or listing from a testing laboratory approved by the department. The statute makes room for what is already installed — equipment in place may continue in use if it complied with the law when it was originally placed and has not been extended, modified, or altered — which is one more reminder that altering an existing system pulls it back under current requirements.

Then comes the record of the work. Under 28 TAC § 34.617, after an installation, modification, or addition — other than in a one- or two-family residence — the licensee completes an installation certificate on the state fire marshal’s format, identifying the standards that apply to the installation and certifying compliance with them. That format governs unless the local authority having jurisdiction requires otherwise. The certificate is presented to the owner or the owner’s representative or posted near the main control panel, and its copies are distributed three ways: the original stays at the site, the certifying company keeps one for the life of the system or ten years, whichever comes first, and one goes to the local authority having jurisdiction — the AHJ, as the trade abbreviates it — within 10 days of completion.

Finally there are the labels, and they are a family rather than a formality. An installation label goes inside the control panel cover after new equipment or a new system is installed, or after an existing system is extended, altered, or modified — it is white with black lettering, carries the registered firm’s details and certificate of registration number, and names both the licensee who installed and the superintendent or professional engineer who planned the system. A service label is completed after any service and signed, and that signature certifies that the service performed complies with the requirements of law. Two further labels report trouble rather than completion. A yellow label goes on the outside of the panel cover — not inside it, where the installation label lives — when a system does not comply with applicable codes and adopted standards, and a red label goes there when a system is inoperable, has a fault condition, or is impaired from normal operation. Each carries a written notification duty to the owner or occupant and to the local authority having jurisdiction, on its own clock, and each stays in place until the conditions are corrected and a service label certifies the correction. Chapter 9 gives the whole family its own treatment.
