B Appendix B Underwriters Laboratories

(UL) Compliance

Installers and sales representatives should familiarize themselves with the requirements of this section in

order to form a better understanding of the requirements for installing this equipment in a UL Listed

environment. The requirement for such listed installations will generally be driven by the local codes,

statutes and regulations, and in all cases the local Authority Having Jurisdiction (AHJ) should be consulted

to be certain that the requirements are known and understood before installing this equipment. UL requires

that controllers, power supplies and the like are installed within the protected area.

Any equipment that has not passed UL294 must not be installed at sites that require conformance with

UL294.

Firmware Updates

For UL294 systems, only UL Listed firmware versions are allowed. Installing non-UL Listed firmware will

void UL Listing. Please contact your support representative before updating firmware in equipment that

requires UL compliance.
