WINGO / TITAN High-Speed Group	WINGOELITE, WG3524HS, LFAB4024HS, TTN3724HS, TTN6024HS

Motor compatibility depends on the exact model code and MC824H revision. Do not advertise all TOONA, all HYKE, all L-FAB or all TITAN motors as compatible without checking the model suffix.

MC824H Is for 24 V Motors

The MC824H is designed for compatible 24 V swing gate motors.

It should not be confused with the NICE MC800, which is intended mainly for compatible 230 V swing gate motors.

MC824H vs MC800

Control Unit	Motor Architecture
MC824H	Compatible 24 V motors with encoder support
MC800	Compatible 230 V swing gate motors

Example: TO5015 vs TO5024

• TO5015 – 230 V TOONA → MC800 family
• TO5024 – 24 V TOONA with encoder → MC824H

This is why the exact motor model is more important than simply writing “TOONA compatible.”

Example: LFAB4000 vs LFAB4024

• LFAB4000 – 230 V underground motor → MC800
• LFAB4024 – 24 V encoder motor → MC824H

BlueBUS Technology

The MC824H provides a dedicated NICE BlueBUS connection for compatible safety and control accessories.

BlueBUS uses two wires to carry both power and communication signals and does not require polarity.

Maximum BlueBUS Capacity

The current NICE technical specification permits a maximum load of 15 BlueBUS units.

Nice specifies this capacity as up to:

• 6 pairs of standard BlueBUS photocells such as EPMB or EPLB
• Additional photocell pairs assigned as opening devices where permitted
• Up to 4 compatible BlueBUS command devices such as EDSB or ETPB

Always follow Nice addressing limits when planning the installation.

Correct Your Current “12 Devices” Statement

Your current page says BlueBUS supports up to 12 devices.

The current NICE MC824H technical table states 15 BlueBUS units maximum.

Therefore, I recommend changing the product page to:

BlueBUS output supports up to 15 BlueBUS units, subject to device type and addressing limits.

NICE EPMB Photocells

The current MC824H manual explicitly lists NICE EPMB among compatible BlueBUS devices.

EPMB can be connected directly to the BlueBUS terminals and must be correctly addressed and learned.

NICE EPSB and EPLB

Other compatible BlueBUS photocell families include EPSB and EPLB where supported by the required installation layout.

NICE EPM Conventional Photocell

NICE EPM is a conventional relay-output photocell and is not the same as EPMB.

Do not connect EPM directly to BlueBUS as though it were a BlueBUS device.

For this page, EPMB is the cleaner direct NICE safety-photocell recommendation.

Encoder Support

The MC824H provides separate encoder inputs for the compatible 24 V motors.

Encoder feedback allows the control unit to monitor motor movement and gate position more precisely than a simple timed controller.

Encoder Wiring

For compatible motors, the motor-power cable and encoder cable must be correctly connected to the corresponding M1 or M2 control channels.

The official current manual indicates that encoder polarity does not need to be observed on the dedicated encoder input.

M1 and M2 Motor Control

The MC824H can control:

• One compatible 24 V swing gate motor
• Two compatible 24 V swing gate motors

For double-leaf gates, the controller manages each motor separately.

Motor Type Selection

The current MC824H includes a dedicated motor selector.

The installer must select the correct motor group before gate-position learning.

Using the wrong motor selection is not permitted and can result in incorrect movement parameters.

Automatic Device Learning

After initial power-up, the MC824H learns the connected devices on the BlueBUS and STOP inputs.

The learning procedure must also be repeated whenever a BlueBUS device is added or removed.

Automatic Gate Position Learning

Once the correct motor group has been selected, the MC824H learns the gate movement and calculates operating positions.

This includes automatic calculation of slowdown points and partial-opening positions where applicable.

Soft Start and Soft Stop

The MC824H manages motor acceleration and deceleration to provide controlled gate movement.

Correct operation depends on correct motor selection, gate geometry, mechanical stops and commissioning.

Obstacle-Sensitive Operation

The controller uses motor and encoder information to detect abnormal movement or resistance when correctly configured.

This function does not replace required photocells, safety edges or other safety devices.

STOP Safety Input

The STOP input automatically learns common safety-contact types including:

• Normally-open contacts
• Normally-closed contacts
• 8.2 kΩ resistive safety contacts

If the learned condition changes, the controller generates a STOP command.

Step-by-Step Input

The SbS input accepts a normally-open dry contact.

This can be used with:

• Push buttons
• External radio receivers
• GSM gate controllers
• RFID readers
• Intercom relays
• ANPR access-control systems

OPEN Input

The dedicated OPEN terminal accepts a normally-open dry contact and commands the opening function.

CLOSE Input

The dedicated CLOSE terminal accepts a normally-open dry contact and commands the closing function.

GSM Gate Opener Connection

A suitable GSM gate opener can operate the MC824H using its isolated dry relay contact.

The GSM relay should normally pulse the OPEN or Step-by-Step input.

Never use a GSM controller to directly power the swing gate motor.

RFID and Access Control

An RFID reader, keypad, intercom or other access-control system can provide a momentary dry-contact command to the MC824H.

Electric Lock Output

The MC824H provides a dedicated 12 VAC electric-lock output rated up to 15 VA.

This is useful where the installed swing gate motor or gate geometry requires an electric lock.

Electric Lock Requirement

The need for an electric lock depends on:

• Motor model
• Gate leaf length
• Gate leaf weight
• Wind load
• Solid gate construction
• Hinge geometry
• Manufacturer-specific motor requirements

Always follow the motor manual rather than assuming every MC824H installation requires or does not require an electric lock.

Flashing-Light Output

The current NICE MC824H specification identifies one NICE ELDC flashing light for the FLASH output.

NICE ELDC Is Correct

The NICE ERA ELDC is the appropriate current flashing-light family for MC824H.

ELDC operates from 12–36 VDC and is designed for low-voltage NICE automation systems.

Remove ELAC from Direct Compatibility

Your current live page lists both ELAC and ELDC.

ELAC is a 90–240 VAC flashing light and should not be described as the standard direct FLASH-output accessory for MC824H.

Use:

NICE ELDC low-voltage LED flashing light.

Radio Receiver Socket

The MC824H includes a standard NICE SM plug-in radio receiver connector.

The current technical manual explicitly identifies compatible receiver families including:

• SMXI
• OXI
• OXIFM

NICE OXIBD

Current Nice system compatibility catalogues also list OXIBD with the MC824H product family.

OXIBD is a modern 433.92 MHz bidirectional receiver, but the actual remote transmitter must support the appropriate radio protocol for the required functions.

NICE OXI

OXI is a compatible plug-in receiver family for MC824H where the required coding and remote family match.

NICE OXIFM Frequency Warning

OXIFM operates at 868.46 MHz.

Do not list normal 433.92 MHz remotes as compatible with OXIFM simply because they are Nice products.

Remote Control Compatibility

Remote compatibility depends on the installed radio receiver.

Always verify:

• Receiver model
• Frequency
• Radio coding protocol
• Remote model

Frequency alone does not guarantee compatibility.

PS324 Backup Battery

The MC824H has a dedicated connector for an emergency / backup battery system.

NICE documentation references PS324 for compatible MC824H systems.

Important Current PS324 Revision Note

The latest Nice manual includes an important warning for current control-unit revisions:

If a PS324 battery pack is used instead of the newer standby-compatible backup arrangement, a separately available connection cable may be required and standby mode must be configured correctly.

Therefore, do not advertise:

“PS324 plugs directly into every MC824H revision with no additional parts.”

Safer wording:

Compatible with NICE backup battery systems including PS324 on supported MC824H revisions; exact cable and standby configuration must be checked for the installed control-unit generation.

Solemyo Solar Compatibility

The current MC824H architecture also provides a connection for the NICE Solemyo photovoltaic power system.

When powered by Solemyo, the automation must not be simultaneously connected to the mains supply.

IBT4N Interface

The MC824H provides a dedicated connector for the optional IBT4N interface.

This enables connection of compatible NICE BusT4 / Opera devices.

O-View Programming

NICE provides dedicated O-View programming documentation for MC824H.

With the correct IBT4N interface, O-View can be used by a professional installer for advanced programming, diagnostics and configuration.

Opera System

The MC824H belongs to the Nice Opera automation architecture and can integrate with compatible programming and automation-management accessories.

MC824H Generations

This is especially important for your product page.

NICE currently publishes separate documentation for:

• MC824H up to September 2018
• MC824H from September 2018 to September 2025
• MC824H / MC824L from October 2025

Therefore, terminal layout, programming details and accessory behaviour can differ slightly between generations.

When replacing an existing MC824H, always verify the exact board/control-unit revision.

MC824H vs MC824HHS

The MC824HHS is a separate control-unit version and should not be treated as identical to standard MC824H.

Do not combine the two model pages unless you have confirmed that your stock and specifications refer to the same unit.

MC824H vs MC824L

The latest 2025 manual covers both MC824H and MC824L, but they are separate model versions.

The MC824H includes encoder connections and uses a 15 A motor fuse, while MC824L has different architecture and limits.

IP54 Protection

The complete MC824H control unit is rated IP54 when the original enclosure is intact and correctly installed.

The current Nice manual explicitly states that the enclosed unit can be installed outdoors when properly mounted and sealed.

Outdoor Installation

For outdoor mounting:

• Install on a solid vertical surface
• Keep the bottom of the enclosure at least approximately 40 cm above ground
• Use suitable cable glands
• Prevent water entering through conduit
• Keep the cover correctly closed

UAE Installation Conditions

Your current page says the MC824H is designed to withstand high temperatures, dust and humidity.

I recommend replacing that marketing statement with the official limits:

Operating temperature: -20°C to +55°C. Protection rating: IP54 when the original enclosure is correctly installed and intact.

For UAE installations, avoid positions where the enclosure can exceed the official temperature limit due to direct solar heating or poor ventilation.

Do Not Claim Unlimited High-Temperature Operation

+55°C is the official maximum operating-temperature specification for the current MC824H manual.

Ambient air temperature and internal enclosure temperature can be higher in direct UAE sunlight, so suitable installation location and protection are important.

Motor Direction Check

After wiring M1 and M2, confirm both gate leaves move in the correct opening direction before completing automatic gate-position learning.

Gate Position Learning

After selecting the exact motor type, carry out the automatic position-learning procedure.

The controller uses the motor encoder feedback to learn and manage movement positions.

Gate Opens but Does Not Close

If the gate opens but will not close, check:

• BlueBUS photocells
• STOP input
• Device-learning status
• CLOSE input
• Encoder wiring
• Gate-position learning
• Mechanical stops

Only One Gate Leaf Moves

If only one leaf operates, check:

• M1 and M2 motor connections
• Encoder 1 and Encoder 2 connections
• Selected motor type
• Single- or double-leaf programming
• Motor condition

Motor Moves in Wrong Direction

Incorrect motor wiring or setup must be corrected before gate-position learning.

Do not leave the automation operating with reversed motor direction.

BlueBUS Fault

If BlueBUS devices are added or removed, repeat the device-learning procedure.

Do not bypass a photocell simply to clear a BlueBUS fault.

Remote Does Not Work

If wired commands operate correctly but the remote does not, check:

• Receiver model
• Receiver installation
• Remote frequency
• Remote coding protocol
• Receiver memory
• Aerial connection
