Simplex · PLCs & Industrial Controllers

Description  The Simplex 400501-00001 is a MuxPad II module used in Simplex 4010 / 4020 / 4100 systems. It functions as a multiplexing / communication interface board to support system communication and device polling.     Technical Specifications  Condition New/Never Used Surplus Brand Simplex / Digitize Category Fire Alarm / Communication Interface Part Number 400501-00001 Subcategory Multiplex / Interface Module Function MuxPad II communication / polling interface Compatible Systems Simplex 4010, 4020, 4100 panels (legacy) Communication Type Multiplex / polling interface Board Type Printed circuit board (PCB) Mounting Type Internal panel module slot / interface bay Status Legacy / surplus only Use Case Multiplex communications / device polling in legacy systems Weight approx. 0.50 lbs (estimate)     Information About 400501-00001 The 400501-00001 is also marketed under the name “Digitize MUXPAD II”. It is intended for use in Simplex legacy panels (4010, 4020, 4100) as a polling / interface interface module. The MuxPad II helps manage multiplexed signalling or communications lines across peripheral devices. While this module is generally declared as surplus or no longer supported actively, it remains in circulation in surplus and legacy parts markets. Key Features: MuxPad II Module: Supports multiplexed communications in Simplex systems. Legacy System Integration: Designed for 4010 / 4020 / 4100 families. Interface Board: Acts as a communication interface or polling module. Multiplex Support: Facilitates multiplexed signaling and device polling. Compatibility: Useful where MUX-based systems are in place. Surplus Availability: Often found as surplus “new-old stock.” Board Form Factor: PCB design for panel mounting. Communication Protocol: Works within Simplex multiplex or communication scheme. No Direct Replacement: Considered legacy with no modern equivalent explicitly stated. The 400501-00001 delivers the reliability and precision required for multiplex communication in legacy Simplex fire alarm networks.
