Device Description

The U‑PROX RM relay expansion modules are the executing devices in an elevator access control system based on the U‑PROX IC E controller, which is designed to control access to building floors. For identification purposes, U‑PROX WRS485 modules with connected Wiegand readers or U‑PROX SE series readers are used.

The U‑PROX IC E controller processes information received from the readers and from the inputs of the U‑PROX RM module, and it activates the permitted relays on the module to control the signaling lines on the elevator floor panel.

Purpose of the Device

The U‑PROX RM module is intended to expand the number of relays and outputs available for access control system controllers, particularly for the elevator controller U‑PROX IC E.

Specifications

Power Supply: External 12V source
Current Consumption: Not more than 400 mA from the 12V source
DC Ripple: Not more than 500 mV
RS‑485 Port: For connection to U‑PROX IC E
Inputs: 8 inputs for connecting cables with current monitoring (termination resistor – 2.2 kΩ)
Relays: 8 relays (NO, NC, COM contacts) rated at 5 A @ 30 V
Alarm Input: EMGR
Case Open Sensor Input: TMP

Terms

Identifiers: In access control systems, each user has an identifier with a unique code. Identifiers may be in the form of a plastic card, key fob, etc.

Reader: A device used to read identifier codes, connected to the ACS controller.

PIN Code: If readers have an integrated keypad, the PIN code entered on the keypad may serve as an identifier or as a supplement to a card or key fob. After a card is presented, the reader waits for the PIN code input.

Door: The access point where access is directly controlled (e.g., door, turnstile, access portal equipped with necessary control devices).

Access Point: See Door.

Passage Time Interval: When a door contact is broken, the access point enters “Alarm” mode; however, an alarm is not triggered if the contact is broken during the predetermined passage time interval. The interval starts when access is granted and ends when the door contact is broken and then restored.

Attempt to Guess an Identifier: The controller features a function that triggers alarm mode if an unregistered identifier is presented repeatedly. A correct presentation resets the counter. This function can be enabled and the number of allowed attempts specified during programming.

Schedules: When configuring user access rights, time and date intervals during which access is permitted are specified. Depending on the module version, up to 250 time intervals and 250 weekly schedules can be stored. Additionally, up to 250 annual holiday dates may be configured.

Time Zones: A time zone is a component of a schedule that organizes time intervals and associates them with access rights. They are used for verifying access permissions and user authorization, as well as for other functions based on schedules.

Loading: After programming the controller parameters, the configuration must be loaded (transferred from the computer to the controller).

Description and Operation

Module Device

The external appearance of the U‑PROX RM relay module is shown in Figure 1.

Function of the Module’s Contacts and Jumpers

LED Indication of the Module

The module’s relay indicator LEDs (R1…R8) reflect the activation or deactivation of the corresponding relays. An LED lights up when its associated relay is energized.

Module Operation

“Normal” Mode: The module is connected to the U‑PROX IC E controller via the RS‑485 bus. The U‑PROX RM relays are connected to the elevator floor selection button circuits. In the de‑energized state, the module allows the buttons to function normally. Feedback cables may be connected to inputs Z1–Z8 from the elevator automation to detect when a floor button is pressed. When such feedback is present, a message “Floor Access Granted” is generated after a button is pressed.

Remote Floor Access Provision

Remote control cables can be connected to inputs Z1–Z8 to provide remote access control (for example, from a security post). When a floor button is pressed at the security post, a message “Floor Opened by Button” is generated.

Emergency Unlocking of the Elevator Control Panel

The U‑PROX RM relay module enters “Alarm – Emergency Unlock” mode if the connection with the U‑PROX IC E controller is lost or if the EMRG input is triggered. Each module is equipped with an EMRG input; in normal operation, the cable connected to this input is short‑circuited to ground. If the EMRG cable is broken or communication with the controller is lost, the elevator control module is de‑energized and full access to the floor selection panel is restored, allowing a user to select any floor without presenting an identifier.

Operating Procedure with the Module

The relay module is provided as a printed circuit board.

Figure 3. Overall Dimensions

Connection Procedure:

• Run the RS‑485 cable, the floor button control cables, and the remote control cables.
• Route the mounting cables.
• Set the module’s address using the DIP switches.
• Mount and secure the module.
• Connect the module to the elevator controller via the ACS software (follow the ACS instructions) and load the full configuration.

After these steps, the module is ready for operation.

Installation Recommendations

The module should be installed in a location that is accessible for maintenance.

Figure 4. Mounting Hole Marking

To install the module on a wall (see Figure 4):

1. Open the housing cover, remove the board, align it to the desired mounting location, and mark the drill holes.
2. Run the cables through the holes in the housing wall.
3. Secure the module’s housing to the wall.
4. Connect all necessary cables.

Connecting Expansion Modules via the RS‑485 Bus

The RS‑485 interface is used to connect expansion modules to the U‑PROX IC E controller. The RS‑485 bus can extend up to 1200 meters without additional equipment. When connecting devices on the RS‑485 bus, enable termination on the first and last devices by setting the termination jumpers (see Figure 5).

When connecting expansion modules:

• U‑PROX RM modules cannot be connected at the ends of the RS‑485 bus because they lack termination jumpers.
• The IDs of the U‑PROX RM modules must not be identical. Set a unique ID for each module using the DIP switches (from 0 to 7).
