Jeron Electronic Systems’ Pro-Alert 480 area-of-rescue system provides persons in distress with hands-free, two-way communication with emergency personnel. The system, which meets federal ADA requirements, is typically used in institutional facilities and commercial buildings. Pro-Alert 480 operates over a common Cat-5 network cable using addressable call stations. Installation costs for the system are significantly minimized because of its minimal need for conduit, wire and labor. Flexible and scalable, Pro-Alert 480 provides small to large critical communication solutions for stairwells and other areas of rescue in parking structures, industrial/commercial buildings and residential high-rise buildings.
