Kantech KT-RM1 External Relay Module Access Control

Product Description

The KANTECH KT-RM1 is an external relay and isolation module designed for use with the KT-300 access control panel. It provides electrical isolation between the controller and external devices, protecting low-voltage control circuits from transient voltage spikes and inductive load interference. Licensed security installers and low-voltage electricians use this module when connecting door hardware, electric strikes, magnetic locks, or other relay-driven peripherals that require circuit isolation. It ships as a single unit and integrates directly into the KT-300 system architecture.

The KT-RM1 is suited for commercial and light industrial access control installations where the KT-300 controller manages entry points and where external relay isolation is required to safeguard the controller board from back-EMF or voltage transients generated by door hardware. Typical applications include electric strike circuits, mag-lock wiring, and auxiliary device switching tied to the KT-300 panel.

Key Features

• Provides electrical isolation for external relay circuits connected to the KT-300 access control panel
• Protects controller circuitry from inductive load transients and back-EMF
• Designed for use with door hardware including electric strikes and magnetic locks
• Sold as a single unit for individual panel or door-point installations

Compatibility

Designed as an OEM-style external isolation module for use with the KANTECH KT-300 access control panel.

Installation Notes

Installation should be performed by a licensed low-voltage electrician or certified security systems technician. Power down the KT-300 panel and all connected hardware before wiring the isolation module. Follow local electrical codes and the panel manufacturer wiring guidelines when connecting external relay loads. Do not energize the system until all connections are secured and verified.
