The Simplex ES MX interface brings an incredible level of capability and flexibility to Simplex systems by enabling powered loop architecture and the use of loop-powered sensors, bases, notification appliances, and peripherals. Compatible with Simplex 4100ES, 4010ES, and 4007ES fire alarm control units, ES MX interface cards provide loop power, device communication monitoring, supervision, and control for up to 250 addressable initiating devices or notification appliances. Multiple ES MX Loop Interface Modules can be used to increase the number of loops and overall system capacity. This approach pairs powerful Simplex networking, graphical workstations, and audio capabilities with UL-listed, EN-approved MX peripherals. MX sensors feature soft addressing and can be paired with a comprehensive range of bases, including standard bases with and without isolation; sounder bases; and sounder bases with beacons. Together, MX sensors and bases can meet the fire protection needs of virtually any space.
