ER502
Streamlined Access Control with ER502’s Tamper-Proof Design
Single- Access Portal Interface Unit
ER502: Enhanced Single-Portal Interface for Secure Access
The ER502 is a RS-485 single access portal reader interface unit designed to greatly increased the flexibility design of the Matrix V system. Door peripherals like readers, keypads and door locking mechanisms are directly connected to ER502 to provide a tamper proof solution and to reduced the cabling works and costing from door peripherals to the main controller.
