The EIS Ethernet Interconnect Switch and the EIRX Industrial Managed Ethernet Switch from Contemporary Controls comply with the requirements of Underwriters Laboratories (UL) 864 Control Units and Accessories for Fire Alarm Systems 10th Edition. All new fire alarm and smoke control systems being installed claiming UL 864 compliance must comply with this latest edition.
The UL recognized component mark is rarely seen by the customer, but is often part of a larger system that is UL Listed by the fire alarm supplier. For a system to be UL Listed, it is evaluated and tested by UL to determine if it meets the requirements established by UL's published Standards of Safety. A UL recognized component has already been evaluated and tested in accordance with UL's component safety standards, streamlining the qualification process for the system supplier.
By having the fire alarm system supplier specify a Contemporary Controls' EIS or EIRX switch as a component, the supplier is not required to perform additional testing on the component. Several fire alarm and security firms have already specified the EIS and EIRX series as part of their system, thereby improving their time-to-market.Components that bear the UL Recognized Component mark are separately covered under UL's Follow-Up Surveillance program to ensure continued compliance and prevent unpleasant surprises when an end-product is inspected.
