KAS S1 Access Control Gateway - Ceiling Mount, Wireless BLE and Sub-GHz, LAN PoE or Wi-Fi
The KAS S1 Access Control Gateway (HGM301) is a ceiling-mounted wireless network gateway designed to connect KAS-compatible door locks and access control readers to the KAS cloud management platform. It forms the central communication hub of a KAS access control system, bridging the wireless signal from door hardware to the site network.
The S1 Gateway supports dual radio frequencies - 2.4 GHz Bluetooth Low Energy (BLE) and 915 MHz Sub-GHz (Sub-1, AU) - enabling reliable communication with KAS NEO, ACR, and PLATINUM lock ranges across a variety of commercial building environments. Each gateway supports up to 60 connected locks and can be powered via LAN Power over Ethernet (PoE) cable or Wi-Fi with a separate DC power supply.
The unit mounts to the ceiling using the supplied clip-on bracket and is designed to be positioned centrally and away from obstructions to maximise wireless range. It is suitable for new installations and retrofit projects across commercial, strata, and multi-tenancy buildings.

Full Specifications
What's in the Box
- KAS S1 Access Control Gateway (HGM301)
- Ceiling fixing bracket (clip-on)
- 3 x mounting screws
Note: AC/DC power transformer and LAN PoE switch are not included and must be sourced separately based on the chosen wiring option.
Installation Tips
- Mount to the ceiling using the supplied clip-on bracket. Route the LAN or power cable through the centre of the bracket before clipping the gateway into place.
- Install with a minimum 500 mm offset from all walls, beams, and other obstructions to preserve wireless range.
- Position centrally relative to the doors being served. Avoid locations above metal ducting, concrete beams, or structural steel without range testing.
- LAN PoE (Option 1) is the preferred wiring method for new installations and sites with more than 4 gateways. Each gateway requires an independent Cat-5/6 cable from the site patch panel.
- Wi-Fi with GPO transformer (Option 2) suits small installations or where LAN cabling is impractical.
- DC loop cable from a remote transformer (Option 3) suits retrofit sites. Refer to the Wiring and Installation tab for DC circuit design data including maximum cable distance and transformer output requirements.
- Gateway commissioning is completed via BLE using the KAS mobile app and should be performed simultaneously with final door lock commissioning.
Frequently Asked Questions
- How many door locks can one S1 Gateway support?
Each S1 Gateway supports a maximum of 60 locks. For larger sites, multiple gateways are deployed and mapped to cover the required floor area. - What is the effective wireless range of the S1 Gateway?
The recommended range is 15 m in unobstructed line-of-sight conditions (maximum 20 m). Through walls or other obstructions such as plaster or concrete, this reduces to 10-12 m. Local site conditions, building materials, and atmospheric factors may affect actual range. - Does the S1 Gateway require a wired LAN connection?
No. The gateway supports three connection options: LAN PoE (wired, preferred), Wi-Fi via a GPO-powered transformer, and Wi-Fi via a DC loop cable from a remote transformer. LAN PoE is strongly recommended for new installations with more than 4 gateways, as it allows remote power cycling and IP management without physical site access. - Is a power supply included with the gateway?
No. The gateway, fixing bracket, and screws are supplied. The AC/DC transformer (for Wi-Fi options) or a PoE-enabled network switch (for LAN PoE) must be sourced separately. Refer to the Wiring and Installation tab for transformer and cable specifications. - Which KAS locks are compatible with the S1 Gateway?
The S1 Gateway is compatible with the KAS NEO, ACR, and PLATINUM lock ranges. Compatibility with other devices should be confirmed with KAS or your authorised KAS supplier prior to installation.
Additional Information
- Wiring Option Selection:
LAN PoE is the preferred option for all new commercial installations, particularly where 4 or more gateways are required. It provides the most management flexibility, including remote power cycling via the network switch. Wi-Fi options introduce dependency on stable building Wi-Fi and may require MAC address whitelisting or a custom SSID on some networks. - DC Loop Cabling - Voltage Drop:
When using Option 3 (DC loop from a remote transformer), cable voltage drop must be calculated before installation. A 12V DC supply is recommended when significant cable runs are anticipated. Full DC Circuit Design Chart data is available in the Wiring and Installation tab. - Gateway Positioning and Site Planning:
KAS recommends mapping gateway positions on a site floor plan prior to installation. Each gateway coverage radius should be plotted at the applicable range to confirm all doors fall within range. Gaps in coverage require an additional gateway. - RF Obstruction:
Metal objects, concrete beams, and dense building materials can significantly reduce effective wireless range. Gateways should not be installed directly above or adjacent to metal cable trays, HVAC ducting, or structural steel without prior range testing. - Installation Sequencing:
Physical gateway installation is typically completed after ceiling painting. Commissioning via the KAS mobile app is performed during the final stage of door lock commissioning. Separating these two activities avoids the need to return to the ceiling after commissioning. - System Scope:
The S1 Gateway is a system component and must be used as part of a complete KAS access control installation. It does not operate as a standalone device and requires the KAS cloud platform and compatible KAS lock hardware to function.

KAS S1 Gateway - Wiring and Installation Guide
The S1 Gateway supports three wiring and power configurations. The correct option should be selected based on site infrastructure, number of gateways, and network management requirements. All three options use the KAS mobile app via BLE for initial gateway configuration.
Option 1: LAN PoE - Preferred Option
Cat-5/6 PoE LAN cable with an active DHCP network. Each gateway is individually supplied by an independent LAN cable from the site internet patch panel rack. Cable endings are patched with a fly cable. This is the strongly recommended option for new installations and sites with more than 4 gateways.
- Each gateway receives its own IP address, configurable and power-cyclable remotely.
- No dependency on building Wi-Fi stability or MAC address whitelisting.
- Remote power cycling via the PoE-enabled network switch - no physical site visit required.
Option 2: Wi-Fi + GPO - 240V AC with AC/DC Transformer
A 240V AC GPO with a DC transformer is installed at each gateway location within building Wi-Fi range. The gateway connects wirelessly to the site Wi-Fi system. Power supply: AC/DC transformer 5V 1A plug (if supplied separately).
- Recommended for small installations with a limited number of gateways.
- Requires stable building Wi-Fi. May require a custom SSID or manual MAC address whitelisting on some networks.
- Power cycling requires a physical visit to the gateway location.
Option 3: Wi-Fi + DC Loop Cable from Remote Transformer
A twin wire pair cable is connected in series between multiple gateways on a floor, powered from a single AC/DC transformer. This option suits retrofit installations where LAN PoE is not feasible and multiple gateways per floor can share a single transformer. Gateway power input connects via a DC plug tail (if supplied).
- Avoids the cost and time of running independent Cat-5/6 cabling to each gateway from the LAN patch panel.
- Cable voltage drop must be calculated before installation - refer to the DC Circuit Design Chart below.
- A 12V DC supply is recommended where significant cable runs or voltage drop is anticipated.
- Power cycling requires a physical visit to the gateway or transformer location.
Wiring and Network Decision Chart
DC Circuit Design Chart (Option 3)
Use the following table to determine the recommended power transformer output for Option 3 DC loop installations, based on the number of gateways per circuit and maximum one-way cable distance.
Cable specification used: 1.04 mm-sq copper cable (Figure 8 Cable 32/0.20 mm at 1.00 mm-sq, or Security Cable 6 Core 14 Strand with 3 cores twisted at 1.29 mm-sq). Cable distance is one-way to the furthest gateway - not round trip. Maximum peak gateway current draw: 500 mA. Maximum gateway voltage supply: 5-11V DC. Use 12V DC supply only where high voltage drop is anticipated.
