UL 1981 sets the standards for the automation system, hardware and communication within the facility. Within UL 827, other standards must be met including UL 1610 (Central-Station Burglar-Alarm Units), UL 1635 (Standard for Digital Alarm Communicator System Units) and UL 681 (Installation and Classification of Burglar and Holdup Alarm Systems). UL 827 pertains to the basic structure of the building and covers physical plant requirements like demised walls, security and fire protection components. UL REQUIREMENTS There are two chief standards written to govern central station design and operation: UL 827 Central-Station Alarm Services and UL 1981 Central-Station Automation Systems. We must be live 100 percent of the time.īuilding engineer Richard Ferrarini shows the scale of the 275-KW diesel generators that supply 24 hours of emergency standby power on a single load of fuel, which will be replenished within four hours of notification. UL central stations do not have the luxury of shutting off services to move. The underlying factor for all telephony issues is that we cannot be down for one second. We had to resolve this issue with multiple carriers for redundancy purposes and to ensure the operation of ancillary services. But since the telephony equipment is located in a different area, the carriers had to find a way to communicate with their own LECs, or Local Exchanges, from the long-distance carrier.
We needed to have a different type of service and receive permission to terminate 773 numbers in an 847 rate center even though the actual telephone numbers don’t matter any more. It would have been a little easier to build in Chicago because we moved out of one rate center to another — from Chicago’s 773 area code to Des Plaines’ 847. This obstacle would have existed regardless if we built a new central station at the old Chicago location or if we had leased space elsewhere, so that didn’t factor into our decision to relocate. However, throughout the 15,000 square feet that is EM24 space, we went above and beyond all prevailing building and industry standards because there were many other considerations like functionality, occupant comfort and the marketing aspect of this facility.įrom the day this project came about, I knew the biggest challenge we faced was moving telephony and the related services because we are dependent on several external carriers to deliver signals. The next step was to create a space plan to satisfy UL 827 Central-Station Alarm Services and design components compliant with UL 1981 Central-Station Automation Systems.
