PRE-INSTALLATION PROCEDURES
Before you begin installing the Brivo control panel, perform the following tasks to ensure a safe, speedy, and successful installation.
Understand the function of the Brivo SDC control panel
The Brivo Single Door Controller (SDC) is a one door control panel with a single access point. This control panel is considered a standalone system with internet connectivity to Brivo Access. The control board has one RS485 connection for one (or optionally two) OSDP reader connections. A second reader is supported for single door in/out antipassback configurations.
The Brivo SDC uses an on-board Ethernet PoE interface to communicate via any TCP/IP networking technology that can be connected through a hub, router or switch, including satellite communications. It is an IP-enabled Access Control System that interacts with the Brivo cloud server via the Brivo Access application.
Understand Brivo Brivo SDC product compatibility
The Brivo SDC control panel allows for the attachment of one primary and one additional OSDP reader directly to the Brivo SDC control panel for the purposes of in/out scenarios (antipassback). As such, the Brivo SDC is compatible with a large number of standard OSDP reader models. Brivo products are designed to accommodate the latest updates in OSDP using RS485 reader formats. The Brivo SDC control board is compatible with OSDP readers using RS485.
A current list of compatible readers and keypads is maintained on Brivo’s website at www.brivo.com. If you have a specific model of reader or keypad that is not listed on the Brivo website, please contact Technical Support at 1-866-BRIVO-4-U to determine compatibility.
Verify that the client site is ready to support the installation
1. Check with the IT department to ensure that the Brivo SDC to be installed is compatible with the company’s local area network (LAN).
- The Brivo SDC is equipped with a standard RJ45 socket that accepts a CAT5 cable with an RJ45 plug on any 10/100 Ethernet network. Physically connecting the panel is the same as plugging any computer or other device into the LAN.
- Refer to the Panel Networking Guide for instructions on connecting to the LAN. The Panel Networking Guide also contains a complete list of requirements regarding TCP/IP configuration parameters and information about security considerations.

Battery
The model of coin cell battery of the Brivo SDC is CR1220 if a replacement is needed.

Tamper
When triggered, the Brivo SDC will generate a tamper event to Brivo Access. It will be visible in the real time event interface and can be configured to generate email notifications.
Tamper for ACS-SDC-E is motion triggered. Once triggered, the ACS-SDC-E will stop after a period of time (10 to 15 seconds) with the reader at rest.
Tamper for the ACS-SDC-E-ENC is a wired tamper attached from the Brivo SDC unit to the enclosure.
In order for the tamper alarm to be audible, an OSDP reader must be attached to the Brivo SDC unit and the tamper alarm will sound through the attached OSDP reader.
WIRING PROCEDURES
Provided below is the wire block diagram for the Brivo SDC unit.
For the Brivo SDC unit to be used for controlling a door, make the following connections:

1. DC Power In is rated from 10V DC to 15V DC. DC Power shall be provided through a UL294 approved Power Supply with Class 2 limited output..
2.Optionally power can be supplied through Power over Ethernet (PoE) through the RJ45 connector.
3. In the case of both DC power and PoE, the ACS-SDC-E will draw power from the DC power source.
Lock Control
The Brivo SDC controls a single door lock through either a magnetic lock or door strike. There are two 12V DC outputs each capable of up to 500mA that can be used to power the door strike in conjunction with the lock control relay.
Lock Relay Output
The relay is rated up to 30V DC and 2A with 0.6 power factor. If power is provided via one of the Brivo SDC’s 12V outputs, the relay power would be 12V DC and the rated output of 500 mA of the Brivo SDC’s limited current. The Brivo SDC lock relay output has both Normally Open and Normally Closed contacts for wiring depending upon your application.

Switched Ground (Aux Output)
Switched Ground output enables or disables a Ground connection. This acts as a electronic relay switch to Ground.
