DSC AMX-400 Loop Repeater/Isolator Module

Improve coverage and system reliability for your security and surveillance installations with the DSC AMX-400 loop repeater/isolator module. As a control panel module designed for addressable loops, the AMX-400 extends allowable wiring distance and re-powers the AML loop—adding 170 mA of current—so you can place detectors and devices farther from the main panel without compromising performance. The unit actively isolates addressable devices and limits the effect of short circuits, protecting the remainder of the loop and simplifying fault diagnosis and maintenance. Powered by a standard 12 VDC source, the AMX-400 can draw auxiliary power from the control panel or an independent supply for flexible installation options. Up to four modules may be wired in series for scalable deployments across large buildings, campuses, or multi-zone monitoring projects. Ideal for fire, intrusion, and integrated security systems where extended run lengths and continuous monitoring are required. Add the DSC AMX-400 to your control panel modules lineup to extend reach, increase device capacity, and minimize downtime—order or consult our technical team for application guidance.

• Extends addressable loop distance so you can deploy detectors and devices farther from the panel without signal loss
• Isolates and limits the impact of short circuits to keep the rest of the loop operational and reduce downtime
• Re-powers the AML loop with an additional 170 mA to support more devices on long runs
• Flexible 12 VDC power options: runs from panel auxiliary power or an independent supply for installation versatility
• Scalable design allows up to four AMX-400 modules in series to support large or distributed security installations
