  • Page 12: Installation

    3.1 Network Overview IMPORTANT: Prior to installation, download the AT-G-ALERT-C floorplan spreadsheet available from Aquilar.co.uk or on the USB stick supplied with the controller. This spreadsheet has editable fields for Floor / Room and non- editable fields for Modbus ID and Gateway IP address. The floor and room fields are to be completed prior to installation in order to ensure correct wiring and function.
  • Page 13 Network Creating Notes: • To mark devices to be on the same floor, those devices must have the same floor name (capitalisation matters). The AT-G-ALERT-C will display a new “floor” tile for each unique name appearing in the floorplan spreadsheet, up to 16 distinct values.

  • Page 14: Floorplan Spreadsheet (Csv)

    3.2 Floorplan Spreadsheet (CSV) When editing the AT-G-ALERT-C floorplan spreadsheet (data.csv) on a PC, it contains placeholder entries for all possible devices in the network. Insert the USB stick into a computer that has Excel software installed. 1. Open the flash drive and click the example CSV file titled “data.csv.” Figure 10 - Open the data.csv File In this file, there are columns labeled: Index, Floor, Room, Gateway, ModbusID, and IpAddress.

  • Page 15: Gateway Ip Address

    3. Save the floorplan spreadsheet as a .csv format and upload it onto the USB stick at the device root folder. The filename must be named as “data.csv” or the AT-G-ALERT- C will not be able to find the file when importing. 4.

This can be done using a windows PC and the free Moxa utility.
  • Page 17 Figure 13 – Broadcast Search 5. When discovered, the Gateway should show up in the table. Select its row and press Configuration. a. Note: if this step requires a password it is “moxa” Figure 14 – Gateway Configuration Navigate to the Network tab (the second tab). Figure 15 - Network tab 7.
  • Page 18 8. If this gateway is the first in the network, its IP address is already correct – 192.168.0.1. If it is the second, change the last digit to be 192.168.0.2, etc. Figure 16 - Network Setting OK screen 9. Repeat this process for the remaining gateways in the system. The gateways contain powerful built-in troubleshooting features.

    3.4 Hardware Installation Mount the AT-G-ALERT-C in an accessible location for viewing alerts and responding to alarm conditions. Environment: place the AT-G-ALERT-C in an indoor setting free from the risk of exposure to water, high humidity or any hazardous conditions. Accessibility: ensure that the AT-G-ALERT-C’s touch screen is readily accessible for viewing alerts and responding to alarm conditions.

    Note: Take care to ensure proper wiring for intended function: normally open and / or normally closed. Figure 18 - Wiring Relays 3.6 Battery for Persistent Memory When 24V DC power is lost to the AT-G-ALERT-C, a backup battery is used to save the current state of the system, including the event history and the date and time settings.
  • Page 21 Connect the Modbus cable to the gateway output as depicted below. Each gateway can support a maximum of 15 AT-G-ALERT devices connected in a Figure 19 - Wiring Gateways daisy chain fashion using the Modbus network cable. Leave no more than 30 cm for the wire tie-off to each AT-G-ALERT. The shield cable may be left floating or tied to electrical GND at the controller only.

    1. Modbus ID Auto-assign: Automatically connect and set IDs using the integrated Magnetic Switch to pair each AT-G-ALERT to its install location. 2. Set Modbus ID Manually: Use the RS485 port on the controller to manually set the Modbus IDs, and then install according to the floorplan, while keeping track of assigned Modbus IDs.
  • Page 25 4. Tap the tile with the first room that is to be commissioned. Figure 24 – Tap the tile of room to commission This should open the Device Modbus Pairing Screen. 5. At the physical AT-G-ALERT device, have a co-worker tap the Magnetic Switch A (marked with a single dot “•”) with the magnetic wand for less than a second, and then pull the magnetic wand away.
  • Page 26 6. Back at the AT-G-ALERT-C touchscreen, after the device has been put into the “Commissioning Mode”, tap Commission Device. When the device has successfully commissioned, a “Success” message will appear. If the commission was unsuccessful, an “Unable to Contact Device” message should appear and the network wiring should be checked.
  • Page 27 8. On the Devices Screen there should be a green checkmark on the device that was just commissioned signaling that the commission was successful. Figure 28 - Green checkmark appears 9. Repeat these steps for each room on a floor and each floor in the building until all AT- G-ALERT devices have been commissioned.

  • Page 28: Method 2: Set Modbus Id Manually

    3.12 Method 2: Set Modbus ID Manually Modbus IDs can be manually assigned to the AT-G-ALERT devices prior to wiring. Wire a single AT-G-ALERT Modbus port to the controller’s Modbus terminal block. It is recommended to use the EZ-wire kit available with the AT-G-ALERT-C controller for ease. 1.
  • Page 29 c. Hold the magnet wand to Magnetic Switch A (marked with a single dot “•” on the AT-G-ALERT) for 60 seconds. The device should beep at the end of 60 seconds to indicate reset. d.
