Line Security and the UL Burglar Alarm Certificate

August 2017

Line Security supervision of communications between a protected property and monitoring station has been an element of UL’s Burglar Alarm Certificate program for many decades. When capable equipment is installed and operated to UL Standards, an alarm service provider can specify the presence of Line Security on any UL Burglar Alarm Certificate.

Recent market developments have generated concern that the UL Certificate program no longer allows the specification of Line Security supervision on Mercantile Burglar Alarm Certificates. Those concerns are unfounded as no such change has been made. The UL Certificate program allows alarm service providers to list Line Security on any UL Burglar Alarm Certificate, as long as the associated requirements are also met.

It is important to note that UL does not require Line Security as an element of protection for Certificated alarm service. Not all businesses require the level of security that Line Security supervision delivers and so UL’s Certificate program allows the flexibility needed to tailor protection to risk.

In many applications, risk managers and insurance providers value Line Security system supervision as a critical security element. A system operated in Line Security mode will detect an attempt to compromise communication pathways between a protected property and a monitoring station. Detection of compromised communication pathways triggers an alarm event at the monitoring station where operators then initiate response actions that limit the amount of time an attacker has to penetrate safes or vaults.

Why is it important to specify alarm system elements on the UL Certificate?

A UL Certificated alarm system consists of several different elements that must comply with applicable codes and standards. When an alarm service provider issues a Certificate on an alarm system, each of those elements is specified and is therefore subject to audit by UL. In other words, The UL Certificate is an alarm company’s declaration that each element specified on the Certificate is delivered in compliance with applicable codes and standards. As a third-party verifier, UL does not audit any element of an alarm system that is not specified on the UL Certificate and therefore cannot provide assurance that those elements are delivered in compliance with applicable codes and standards. In some cases, such as Line Security, this may be a cause for concern for some risk managers and insurance providers.
