Alarm system certificate
When a certificate is issued for an alarm system, it is the alarm company's declaration that the system will be installed, maintained, tested and monitored in accordance with applicable codes and standards.
Auditing certificated systems
UL tracks each certificate carefully. We visit every Listed alarm company at least once a year to audit certificated systems. During the audit, service and alarm handling records are reviewed. In addition, UL alarm specialists randomly select a number of certificated installations and conduct a physical inspection. If noncompliance is found, the alarm company must rectify the problem or face cancellation of the certificate.
Request a certificate
It is important to ask for a certificate when working with a UL Listed alarm company. UL only audits installed systems for which certificates have been issued. See our Alarm System Certificate Services page for more details on the difference between these designations.
What the certificate contains
Each certificate identifies the type of alarm system, the name and address of the property protected by the system, and the name and address of the alarm service company responsible for issuing the certificate. A description of the equipment installed, its coverage and other protection details are included. Every certificate has a unique serial number, issue date and expiration date.
