CIA-675-001 Rev 1.1 INSTALLATION General: The gateway is designed to manage access to or from a series of secured areas. It operates in conjunction with a central database that contains a list of access codes and areas these codes are valid for.
CIA-675-001 Rev 1.1 2. Mount the back plate to the desired Gateway location, (which must be inside a protected area) using the 4 grommet filled holes in the back panel shown. There are also a series of knock outs in the back and the floor of the enclosure for pulling the wires through. Figure 2 –...
CIA-675-001 Rev 1.1 Wiring Connections: Below is a connection diagram for the Gateway. Note: All installations must conform to local building and electrical codes and shall be in accordance with the National Electric Code, ANSI/NFPA 70. When discrepancies exist between local codes and this manual, local code takes precedence. All cables entering the gateway should be insulated and shielded with drain wires connected to earth ground at one end.
CIA-675-001 Rev 1.1 Incoming PWR: Incoming power (15-24VDC) is connected to the connector at the bottom left-hand corner of the board. Figure 4 “To Power Supply”. A 24V 5A DC supply is provided by default. One suggested P/N is SDI120-24-U-P51 by CUI. This is sufficient for systems having up to 6 keypads. If more devices are required a larger DC supply would be required.
CIA-675-001 Rev 1.1 Wireless Communications (Optional): The Gateway can also function without the RS485 wiring. In this case the XBEE or XBEE Pro 900 MHZ wireless module and an RPSMA antenna must be installed on the system Gateway and on the remote device to operate wirelessly. If the keypad or relay unit is within wireless range of the Gateway, the keypad will work in same fashion as with RS485 connections.
CIA-675-001 Rev 1.1 Inputs: Each Input has a Ground Connection (G) and a Sense Connection (1). The sense connections are marked 1-8 and will source a small voltage at high impedance. Wire any dry contact across a sense pin and a G pin.
CIA-675-001 Rev 1.1 Testing the Gateway Hardware Test the Gateway by applying power to the Incoming power connection. There are multiple LEDs as shown below that should be active as described for troubleshooting purposes. Check the 3 Power Indicator LEDs PCB. If all are dark, check / replace the PCB main fuse. If any single specific power LED such as the 3.3V or 5V LEDs are dark, replace the main PCB.
CIA-675-001 Rev 1.1 As a default each RS485 channel is fused at 3.1A slow blow fuse. This is sufficient for powering 6 Keypads and/or Relay Units per channel. If a larger number of devices are required, they must be externally powered from a different DC source.
CIA-675-001 Rev 1.1 GATEWAY MAINTENANCE Cleaning: Yearly: Open the Gateway cabinet, inspect and clean the inside of the unit. Remove dirt or dust that has collected on the inside of the housing and the circuit board that could cause problems. Note any signs of water damage or corrosion caused by a leak in the enclosure seals.
