SecuraKey Single-door Controller, RS485, HF, Rectangular Mullion style, Black | SKY-ET-SR-X-R

ET-SR-X-R (The ET-SR-X-R is an upgraded version and a direct replacement for the ET-SR-X-M)

The ET8-SR reader connects to the NOVA.16 Controller via the RS-485 peripheral bus, which supports up to 16 readers. The ET8-SR obtains data communications and 12VDC power from the NOVA.16, but it has all the inputs and outputs required to monitor and control a door or gate. The reader sends card data and input status changes to the Controller, and receives access granted, access denied, and output control commands from the Controller. All door connections (Strike/Latch, REX, Door Monitor, aux inputs, and outputs) are made locally at the Smart Reader. Cable “Home Runs” from the door location back to the NOVA.16 Controller are not required.

NOVA.16’s RS-485 Peripheral Bus may extend up to 4000 cable feet from the control panel. ET8-SR’s may be connected to the NOVA.16 in a daisy-chain, multi-drop, or loop configurations, providing great flexibility in system architecture.

The ET8-SR-X-M is a mullion-sized reader which fits a standard door frame. It is epoxy-potted for outdoor installations. It includes a convenient wiring harness, which allows the reader to be plugged in when the installation is completed.
