The IP wall reader enables contactless unlocking of doors with an RFID chip and/or PIN code as two-factor authentication. The IP wall reader always consists of the actual wall reader and the SmartRelay module. The SmartRelay module can be extended to two wall readers. Further wall readers are integrated into the system via further SmartRelay modules in the master-slave procedure. In this way, there is virtually no limitation to the number of doors. The SmartRelay modules can be mounted on a standard DIN rail or in a 60mm switch box. The wall reader is available in different versions for interior/exterior use, flush-mounted or for installation in intercom systems. The configuration and wiring are essentially always the same.

To be able to switch alarm zones on a wall reader, the following requirements must be met:

  • In the configuration of the AccessManager, an AlarmManager must be connected
  • In the user settings of the user, the authorization to switch alarm zones must be activated
  • A PIN and/or RFID token must be assigned to the user
  • The alarm zone must be selected in the configuration of the wall reader

If the requirements are met, the arming or disarming button can be pressed and then the PIN can be entered or the booking can be made with the token. If the action is successful, the LED lights up green and the zone is armed or disarmed.

*The terminator is used to prevent reflections within the bus connection. It is inactive by default. If the wall reader does not work after connection, the DIP switch for the terminator can be set to ON. The reader should then work correctly.

Reflections occur, for example, at device connections and due to irregularities in the conductor. If you have for example a long supply line, it is possible that the reflections become so large that it is necessary to switch on the terminator.

General Connection Diagram SmartRelay with RFID Wall Reader

Detailed Wiring and Terminal Diagram for two Doors

The following wiring diagram shows the general wiring of the SmartRelay module with two wall readers and two door contacts for monitoring the door status. The readers are connected via a BUS (RS485) with a total cable length of up to approx. 600m. As connection cable we recommend I(ST)Y-2x2x0.8 between SmartRelay and reader. The SmartRelay module is powered via Ethernet PoE. The module supplies two 24VDC voltage outputs as PoE splitters to supply the readers and the lock control. When supplying power to the locks (door opener, motor lock, magnet holder), please note that the splitter can supply a maximum of 10W of power. If more power is required for activation, the locks must be supplied with power via an external power supply unit. The advantage of using the splitter and PoE is the simultaneous emergency power supply of the door control when using a UPS at the PoE supplying switch.

  • The two readers are always supplied with power from the SmartRelay module. Power supply and communication bus (A+B) are routed in one cable.
  • The two relays (Rel1+2) can be set to the required logic NC/NO (Normally Closed/Normally Open) via jumpers.
  • The two door contacts at input 1+2 (DI1+2) require a potential-free contact (e.g. reed contact) for connection to DI1+2.
  • *The power supply by the PoE splitter can be replaced by an external power supply. This is necessary if the splitter does not supply the appropriate voltage (24VDC) or the required power (>10W).

Control of External Intrusion Alarm Systems

By means of a corresponding software configuration via the web interface of the integrated web server, it is possible to control external intrusion alarm systems with automatic control. In this context, forced operation means that an activation of the alarm system or an alarm zone is only possible if, for example, all windows/doors are closed and the alarm system releases the SmartRelay module. In principle, the wiring is always the same, depending on the software setting, the evaluation can be carried out with or without a query of the forced operation. The inputs must always be connected potential-free, the logic levels for the transfer are always continuous levels, no pulses. One alarm zone can be controlled per relay module, several doors in one zone require the corresponding number of relay modules.

When controlling an external alarm system, the SmartRelay module can only control one door, as the second relay is required to switch the alarm function. However, it is still possible to use two readers (inside and outside door).

  • READY TO ARM (Input: DI2): External alarm system signals that arming is possible (positive action).
  • ARMED (Input: DI1) : External alarm system signals that zone/system is armed.
  • ARM-DISARM (Output: Rel1): Arm/disarm switching of alarm system via output relay 1
  • DOOR-LOCK (Output: Rel2): Control of the door lock, independent of the alarm system.

All levels are continuous levels, no pulses and are permanently present according to the switching time. The logic of the relay (Rel1) can be changed via jumper JP1. The input levels of the digital inputs (DI1+2) are fixed. The HIGH level signals the described function, e.g. READY-TO-ARM = 1 or ARMED = 1.
