Addressable Fire Detection / Modules Modules This Sounder Control Module interfaces between the Analogue system via a ST-SC2B-SC or conventional sounder O/Ps and the intrinsically safe sounder/beacon units via an intrinsically safe barrier. ST-I1B Model ST-RC1B-SC is a Single Input/output Module, which provides a single, mains-rated relay output for the control of such devices as dampers, extractors or plant and equipment shutdown. ST-I2B-SC Model ST-I2D-SC is a Dual Input Module designed to interface to a variety of inputs such as door contacts, sprinkler flow/door switches and plant equipment. ST-I2D-SC The ST-MR Assembly is a set of replacement components designed to fit any of the existing ST Modules: ST-I2B-SC, ST-ZM1B-SC, ST-ZM2B-SC, ST-SC2B-SC, ST-RC1B-SC, ST-RC2B-SC, ST-I1B and ST-PC4B. ST-MR The ST-O1B has been designed to allow a single relay output to be connected to the ESP loop. ST-O1B The ST-PC4B-SC is a loop powered input/output module with four independent changeover relay outputs and four monitored inputs. ST-PC4B-SC The unit is small enough to be added to other third-party devices thereby allowing a range of equipment to be added to the ESP loop. ST-POC The unit is small enough to be added to other third-party devices thereby allowing a range of equipment to be added to the ESP loop. ST-RC1B-SC The monitored input can be used for local power supply fault monitoring or as a general-purpose input ST-RC2B-SC Model ST-SC2B-SC is a Dual Sounder Controller, which has been designed to provide two sounder outputs (that can be driven separately) with full fault monitoring. ST-SC2B-SC Model ST-ZM1B-SC is a Single Zone Monitor designed to allow up to 6 conventional detectors to be interfaced to the ESP analogue addressable system. ST-ZM1B-SC Model ST-ZM2B-SC is a Dual Circuit Zone Controller designed to allow up to 60 conventional detectors (30 on each zone) to be interfaced to the ESP analogue addressable system. ST-ZM2B-SC
