Gateway - Datasheet




Information


The Gateway is used to connect the lock hardware to the KAS cloud server. The gateway(s) need to be within range of all of the online devices which is best achieved by placing them in central and unobstructed locations.
  1. Mount the gateway to the ceiling using the supplied bracket. (Clip on).
  2. Ensure the gateway is not covered or blocked by metal objects or any other obstructions such as concrete beams which could dramatically reduce the effective operating wireless range. Like any wireless protocol device, the optimal results will be achieved when within direct line of sight and the closest proximity (range) from the target devices.
  3. Connect the gateway to the network by either LAN cable (wired solution) or WIFI wireless solution (see below)
  4. Connect the power adapter to the gateway if not using LAN PoE (Power over Ethernet)
  5. The gateway must be installed in a location that will allow the operators easy access the occasional reseting or updating of WiFi credentials etc. It is also a requirement that the gateway be in a position to be able to see the LED light indicators.
  6. The signal strength for a gateway to all devices is strongly recommended to be = -70

Wiring and Cabling

There are 3 cabling/wiring options for data and power. 

Option 1: LAN PoE (Preferred Option)

Cat-5/6 PoE LAN cable with active DHCP network (cable endings to be patched with a fly cable). Each Gateway required to be individually supplied by an independent LAN cable from the site internet patch panel rack.



Option 2: WIFI + GPO - 240V AC Power Point with a AC/DC transformer


GPO 240V AC GPO with DC transformer at each gateway location, located within building WIFI range. The gateway can then be linked wirelessly to the site WIFI system.

Power supply: AC/DC Transformer 5V 1A plug (if supplied): 



Option 3: WIFI + DC Input - Connecting multiple gateways in series using a DC loop cable from remote DC Transformer

Twin wire pair cable connected in series between multiple gateways powered from a single transformer per floor. This option is ideal for existing sites where multiple gateways are located on each floor that can then be supplied from a single AC/DC transformer. This option prevents the additional cabling/time/cost requirements of running independent Cat 5 cabling to each individual gateway from the existing LAN Patch panel, most often located quite remotely away from most floors.


Gateway power input is connected with a DC plug tail (if supplied).

  1. Consider cable voltage drop if using Option 3.
  2. The maximum cable distance and approximate cable voltage drop can be calculated using the following design charts in Appendix A.
  3. See Appendix A to determine maximum cable distance and number of gateways per DC circuit.

Wiring and Network Decision Chart

For the above wiring options please consider the following points:

Recommended Wiring
Strongly Recommended for new installations and sites with many gateways.(e.g greater than 4 gateways)
Option 1: LAN PoE
Recommended when installing a small amount of Gateways.

Option 2: GPO Power
Used for retrofit installation where LAN PoE is not possible.

Option 3: DC Circuit
Activate the Gateway with Mobile App using BLE for initial configuration

YES
YES
YES
Each gateway will have its own IP address which can be configured and power cycled remotely without visiting the device
YES
NO
NO
Gateway power cycles required to physically visit the gateway (sometimes enter roof cavities or comms rooms)

NO
YES
YES
Requires DHCP only network and stable WIFI connectivity (May need a custom SSID or manual whitelisting of gateway MAC address on network for stable connectivity)

NO
YES
YES

Gateway Positioning and Mapping

The following information to determine the gateway position has been supplied as a general recommendations only.
KAS cannot guarantee this information will be suitable for all site conditions. Please consider all environmental aspects when mapping and installing your gateways.
Local site environment, hardware, building materials, interfering technology and atmospheric conditions may affect the recommended maximum reception ranges. 
This may result in poor coverage in certain areas, meaning adjustments in the placing of gateways or even requiring more than recommended.

Maximum Number of Lock Hardware to a Gateway: 60 lock hardware to a gateway

Notes for Installers
The installers will be required to physically attach the gateways, which would normally be done following the final painting of the ceilings/walls. This task could generally be done by the same team connecting the ceiling-mounted WIFI access points (WAPs).
The gateway commissioning would normally be completed simultaneously by the person who is doing the final commissioning of the door locks. 
Ensure the Gateway is installed with at least 500 mm offset from all walls, beams and other obstructions.

Disclaimer:

KAS will not be held responsible or liable for any site internet connection issues relating to the internet connection between the KAS Gateways and the KAS Cloud servers (KAS Console accounts). KAS hardware products including the Gateways which connect to the KAS lock remain under KAS standard warranty terms and conditions, however, the client’s site internet connectivity and related issues involving connection through the sites internet will be the responsibility of the client and/or their engaged IT/Network Manager and their selected Internet Service Provider. This disclaimer applies to all internet communications whether by WiFi, Cable and/or Mobile Network Routers.


While KAS will provide standard technical support services to assist with identifying such connectivity issues resulting from the KAS Gateway functionality to the KAS Locks (including Battery operated locks and the Access Control Readers), we are not responsible (or liable) for any unreliable (or failed) data transmission issues resulting from the KAS Gateways passing through the site’s internet, The resolution any site Internet issues remains the responsibility of the client and/or their own engaged IT personal and their Internet provider.



Wireless characteristics disclaimer. Due to shadow fading factors, the communication between the gateways and lock hardware may sometimes vary. This may occur when there is a multi path propagation which could be caused by numerous elements such as weather (particularly rain or variations in humidity) or any shadowing obstacles, affecting the wave propagation. These effects can vary from site to site, and even at the same site over different periods of time and may often become noticeable as a signal loss with potential resultant intermittent reductions in product performance. This characteristic of wave propagation can affect any and all hardware items and is not a reflection on any particular product.

APPENDIX A – DC CIRCUIT DESIGN CHARTS

Use the following tables as a guide to determine a recommended Power Transformer Output for the Number of Gateway vs Cable Length. 

Table 1: DC Circuit Design Chart

Example Cable spec: 
Figure 8 Cable 32/0.20 mm (1.00 mm-sq area)
OR
Security Cable 6 Core 14 Strand (0.43 mm-sq per core) 3 cores twisted together (1.29 mm-sq)
  1. Cable specs are used in the below table: (1.04 mm-sq copper cable)
  2. Cable Length: is calculated as a one-way distance to the furthest gateway. Not round trip distance. 
  3. Maximum Peak Gateway Current Draw: 500 mA
  4. Maximum Gateway Voltage Supply: 5V – 11V DC 
    Note: 12V DC Power supply should only be installed when you anticipate a high voltage drop.
