Installing the access control equipment

You can connect a lightweight access control feature to Systam Visit (Systam Gateway Service, SGS) that opens a single door or gate, without building a full integration to a dedicated access control system. The door or gate is opened by a small relay controller.

Three ways to trigger the relay

• QR code reader: the reader scans the QR code on the visitor badge or in the pre-arrival message and opens the connected lock.
• Virtual button: tapping the button in the visitor's pre-arrival message (SMS or email) triggers the same relay, no visitor badge needed.
• Front desk: staff signed in to RespaManager can trigger the relay directly from the front desk, for a pre-configured door or gate.

All three methods use the same relay controller — only the trigger differs. You can also limit access by time of day and by a time window around the visit.

What you need before installing

• A 9–28V DC power supply for the relay controller. If only 230V is available in the electrical cabinet, Systam can also supply a DIN-rail 230VAC → 24VDC power unit.
• A wired network connection to the internet (RJ45).
• If you're installing a QR code reader: a USB cable between the reader and the relay controller.
• Wiring from the relay controller to the door or gate opening circuit.

Installation

1. Mount the relay controller on a DIN rail, typically inside the electrical cabinet for the door or gate.
2. If you're using a Systam-supplied power unit, mount it on the DIN rail too and connect the 230V supply to it. Wire its 24VDC output to the relay controller's power input (9–28V DC).
3. Connect a network cable (RJ45) to the relay controller for the internet connection.
4. Wire the controller's relay output O1 in parallel with the existing door-opening button. When the controller receives a valid trigger, the relay closes for a few seconds — just like someone pressing the button.
5. If you're installing a QR code reader, place it outside the door or gate and connect it to the relay controller with a USB cable. The relay controller itself always stays indoors, away from condensing conditions.

Access rights and the check for a valid Systam Pass induction are set up in RespaManager's access control settings. Every entry is logged in Systam Visit.

Firewall and network access

The relay controller needs outbound access to RespaManager over the internet connection you set up in step 3.

Whitelist by domain name rather than IP address, since the address can change without notice. If the controller doesn't come online after installation, this is the first thing to check with the customer's IT team — see also Kiosk network requirements for the full picture of what else the site's network needs to allow.

Technical specifications

Good to know: the QR reader can be installed outdoors, but the relay controller and any power unit always belong indoors, in non-condensing conditions.

All set! The door or gate now opens with a visitor's QR code, the pre-arrival button, or a helping hand from the front desk.
