Suprema CoreStation 20 2-Door Access Controller, 500,000 Users, 4 Relays

Overview

The Suprema CoreStation 20 is a two-door access controller. It keeps user and access data centrally and decides who may open each door, while card readers at the doors only read credentials. It suits offices, shops, clinics, schools and businesses that expect to add doors later.

Is it right for you?

Choose it for one or two doors run from a central controller, with room to grow using Suprema Door Interface (DI-24) modules. For more doors on one panel, or stored fingerprints, look at the CoreStation CS-40.

Choosing your version

Both versions have the same doors, ports, relays and capacities. They differ in power and in one security feature.

• CS-20: powered from 12 V DC (2.8 A) or 24 V DC (1.4 A)
• CS-20P: adds PoE+ (IEEE 802.3at) power over the network cable and a SAM slot for secure smart card authentication

Pick CS-20P if you want the controller fed from a PoE+ switch, or if your card scheme uses a SAM card. Otherwise CS-20 does the same job from a DC supply.

Key features

• Controls 2 doors, with up to 500,000 users, 500,000 cards and 500,000 PINs
• Up to 5,000,000 text event logs
• 4 relays, 6 inputs (TTL or supervised), 6 outputs
• 3 auxiliary inputs: AC power fail, tamper and fire
• 3 RS-485 ports (OSDP V2) and 2 Wiegand reader ports; up to 4 RS-485 devices and 2 Wiegand devices
• Offline facility code mode keeps doors working if the serial link to a Door Interface fails
• Encrypted data with a crypto chip

What else you need

• Card or PIN readers that use RS-485 (OSDP) or Wiegand, such as Suprema XPass D2
• A 12 V DC (2.8 A) or 24 V DC (1.4 A) power supply, or a PoE+ (IEEE 802.3at) switch or injector for CS-20P
• Door locks, exit buttons and door sensors (door position sensors)
• Suprema BioStar access control software on a computer or server

Installation

Mount it in a secure, indoor place near the doors it controls. It connects to the network by Ethernet. Readers, locks and sensors are wired to it, so plan cable runs first.

Software and licences

Managed from Suprema BioStar 2; Suprema also lists BioStar X. Whether a software licence comes with the controller is not stated by the manufacturer.

Before you buy

• CS-20P needs PoE+ (IEEE 802.3at, 30 W) or PoE++. Standard PoE (IEEE 802.3af, 15.4 W) is not supported and may damage the controller
• Operating temperature is 0 to 50 °C, so it is for indoor installation
• It stores cards and PINs; fingerprint and face capacities are not listed for this controller
