The CRF-300(A) Addressable Relay Module provides the sys- tem with a dry-contact output for activating a variety of auxil- iary devices, such as fans, door holders, dampers, control equipment, etc. Addressability allows the dry contact to be activated through panel programming, on a select basis. LiteSpeed is a communication protocol developed by Fire?Lite Engineering that greatly enhances the speed of com- munication between analog intelligent devices. Intelligent devices communicate in a grouped fashion. If one of the devices within the group has new information, the panel CPU stops the group poll and concentrates on single points. The net effect is response speed greater than five times that of other designs
