Central Station Facility Operations include Emergency response personnel that must be available and "on-site" 24 hours, every day. Records tracking standards on equipment maintenance and staffing must be kept. Back-up communication methods to public service authorities must be in place. UL mandates the number of operators on duty per shift. Non-UL stations have no requirements. Most have only one operator, especially in the late evening/early morning.

Central Station Equipment Standards Alarm receiving equipment must have a redundancy (back-up) in case of equipment failure with 30-second switch over to insure no "down time". A generator must be in place that automatically takes over powering of all central station equipment in case of AC power failure. Central Station must have uninterruptible power supply that insures constant filtered power to equipment and in effect is a fail safe of at least 4 hours back up to generator.  Earning and maintaining the UL certification is not an easy or inexpensive undertaking for a company. HDJ Security has chosen to be a UL Certified Central Station because it means superior service and greater safety for our customers and clients.
