Hardware Installation
The MR52 hardware installation process is straightforward and designed to ensure a secure and reliable connection. Begin by carefully selecting a suitable location for the MR52, taking into account factors such as proximity to power sources, communication cables, and the intended access points. Once the location is chosen, proceed with mounting the MR52 using the provided mounting hardware. Ensure a secure and stable installation to prevent any potential damage or malfunction.
Next, connect the power supply to the MR52. Refer to the power specifications outlined in the manual for the correct voltage and current requirements. Carefully connect the power cable to the designated port on the MR52 and ensure a secure connection. After powering up the MR52, proceed with connecting the communication cable to the RS-485 interface port. This cable connects the MR52 to the Mercury intelligent controller, enabling communication and data exchange between the devices.
The next step involves connecting the card readers to the designated ports on the MR52. Refer to the specific instructions provided for each reader type to ensure proper connection. Once the card readers are connected, proceed with connecting the input monitor points to the MR52. These input points are used to monitor various security events, such as door openings, alarm activations, or other relevant events. Carefully connect each input point to the corresponding port on the MR52, ensuring a secure connection.
Finally, connect the control relay outputs to the locking hardware or other devices you intend to control. These outputs provide control over various functions, such as door locking, alarm activation, or other actions. Refer to the documentation for specific instructions on connecting the control relays.
Communication Setup
The MR52 relies on a robust communication system to exchange data with the Mercury intelligent controller, enabling seamless integration and control over various security functions. The communication setup involves configuring the MR52’s communication parameters to ensure proper communication with the controller. This configuration typically involves setting the communication address, baud rate, parity, and other relevant parameters.
To initiate the communication setup, access the configuration menu of the Mercury intelligent controller. This menu usually provides options for adding new devices and configuring their communication settings. Select the option for adding a new device and specify the device type as an MR52. The controller will prompt you to enter the communication address for the MR52. Refer to the documentation for the specific address range supported by the controller.
Next, configure the communication baud rate. This setting determines the speed at which data is transmitted between the MR52 and the controller. The baud rate is usually set to a standard value, such as 9600 baud, but it may vary depending on the specific model of the controller. After setting the baud rate, configure the parity setting. This setting ensures the integrity of data transmission by adding an extra bit to each data byte. The parity setting can be set to even, odd, or none, depending on the requirements of the system.
Finally, configure any other relevant communication parameters, such as the data bits and stop bits. Once all communication parameters are set, save the configuration and verify communication between the MR52 and the controller. This can be done by sending a test command from the controller to the MR52 and verifying the response.
Reader Configuration
The MR52 boasts flexibility in configuring card readers, allowing you to tailor the system to your specific security needs. The configuration process involves setting parameters such as reader type, access control modes, and reader-specific settings. To begin, identify the type of card readers connected to the MR52. The MR52 supports a wide range of card reader technologies, including proximity cards, magnetic stripe cards, and smart cards. Select the appropriate reader type in the configuration menu of the Mercury intelligent controller.
Next, configure the access control mode for each reader. The MR52 offers various access control modes, such as card-only access, PIN-only access, or combined card and PIN access. Choose the access control mode that best suits your security requirements. For example, if you require a two-factor authentication, select the combined card and PIN access mode.
Further, configure the reader-specific settings, such as the read timeout, beep volume, and LED behavior. The read timeout determines how long the reader waits for a card to be presented before it times out. The beep volume allows you to adjust the loudness of the reader’s beep. The LED behavior allows you to customize the LED’s color and pattern for different events, such as a successful card read, an invalid card, or an access denied.
After configuring the reader settings, test the reader by presenting a valid card and verifying its functionality. Ensure the reader can read the card correctly, authenticate the user, and trigger the appropriate actions, such as opening a door or activating an alarm.
Alarm and Control Output Wiring
The MR52 provides six Form-C relay outputs that can be utilized for various purposes, such as controlling locking hardware or signaling alarms. These outputs are configurable through the Mercury intelligent controller, allowing you to assign specific functions to each relay. For instance, you can program one relay to control the door strike, another to activate an alarm, and another to trigger a specific event in your security system.
When wiring the relay outputs, ensure that you use the appropriate wire gauge and type to prevent overheating or damage. Refer to the MR52’s technical specifications for the recommended wire gauge and type. The MR52 also includes eight input points that can be used to monitor various events, such as door status, tamper switches, or other sensors. Each input point can be programmed to trigger a specific action in the Mercury intelligent controller, such as activating an alarm or logging an event.
For example, you could configure an input point to monitor a door’s status, triggering an alarm if the door is opened during unauthorized hours. When wiring the input points, use appropriate wire gauge and type, ensuring proper grounding and shielding to prevent interference. Consult the MR52’s technical documentation for detailed wiring instructions and recommendations.
The MR52 provides flexibility in configuring the alarm and control outputs, allowing you to build a robust and customized security system that meets your specific needs.
