Requirements and Recommendations

Gateways need to be installed in locations that can reach the lock hardware.

There are many aspects to consider before installing the gateway which includes the following:

location and distances for the best coverage
obstructions that may affect the range of the gateway
powering and connectivity requirements

To ensure the gateway will have sufficient coverage to the locks please reviewed the Gateway Datasheet before installing the gateway

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.

Mount the gateway to the ceiling using the supplied bracket. (Clip on).
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.
Connect the gateway to the network by either LAN cable (wired solution) or WIFI wireless solution (see below)
Connect the power adapter to the gateway if not using LAN PoE (Power over Ethernet)
The gateway must be installed in a location that will allow the operators easy access the occasional resetting 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.
The signal strength for a gateway to all devices is strongly recommended to be = -70

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.

The maximum number of locks-to-gateway recommendation is 60 locks for 1 gateway

Range Guide for Gateway to Lock Hardware

The below chart has been provided as a guide only and may not be accurate to your site. Other Interferences may reduce the range.

Obstruction	*Range meters**
Direct Line of Sight	10-15
Obstructed (Drywall / Plaster board) etc	8
Plastic / Glass / Wood Doors	8
Brick / Concrete Walls	5
Strong winds / weather conditions	Can affect range
Electrical Hardware	Can affect range
Electrical Signals / Shadowing	Can affect range

Angle recommendation for Gateway to Lock Hardware

Due to the position of of the antennas in the gateway, it is also a good idea to take into account the fact that there are blind spots / areas of weaker signal on either end of the antennas.

The Sub-1GHz Antenna is located as marked, on the end of the gateway opposite the side with the Reset Button.

Example 1: With the antenna orientation facing the hallway, rooms 102 and 105 will be in its blind spot, negatively affecting the signal strength. Rooms 103, 106, 104, and 101 should still have acceptable signal despite them being further away.

Example 2: An additional gateway added and the first gateway shifted to avoid the blind spots. This would be the ideal deployment.

Example 3: If a minimal-gateway deployment is preferred, the gateway can be oriented to provide broader coverage at the expense of signal quality to further rooms. Rooms 101, 104, 103, 106 aren’t entirely in the best signal area, but they’re close enough to the edges that signal should be OK.

Note: In this example, rooms at the very end of the hallway will already be in the blind spot.

Note: It is worth noting that signals do bounce / reflect off certain surfaces, such as plants and walls, and especially metal walls, elevator shafts and aluminum-composite panels.

The above examples show typical deployment scenarios, with Example 2 being the ideal deployment. These do not take into account environmental factors such as the ones stated above.

Notes and Disclaimers

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 that the gateway is installed with at least 500 mm clearance from all walls, beams, or other obstructions.

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.

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 / Access 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.

Configuration

There are 3 ways to configure the S1 Gateway. Please follow the instructions relevant to your wiring requirements.

Note: You only need to follow one method.

PoE Option: (LAN + Power Over Ethernet)
WIFI Option: (DC Plug + WIFI)
LAN Option: (DC plug + LAN cable)


For PoE: Plug the PoE LAN cable into the base of the gateway as pictured, this needs to be connected to your router. No power supply required.	For WIFI: Plug the PC Plug into the base of the gateway as pictured. 5V DC power is required	For LAN: Plug the LAN cable into the base of the gateway as pictured, this needs to be connected to your router. 5V DC power is required
