A power failure can stop an elevator between floors and leave passengers waiting inside. An Automatic Rescue Device (ARD) uses backup power to move a compatible lift to a suitable floor, allowing passengers to exit when the rescue sequence operates correctly. The device, battery and elevator control system must all be compatible for this process to work as intended.
When planning elevator ARD replacement in the UAE, start by checking the existing unit's model number, power rating and battery requirements. Selecting a replacement based only on price or power rating can lead to compatibility problems. A few checks before ordering can help maintenance teams find the right part and avoid unnecessary delays.
What to Check Before Replacing an Elevator ARD
An ARD supports emergency elevator operation during a power interruption. If the system fails, passengers may remain inside until trained personnel carry out a rescue.
A qualified elevator technician should first identify the source of the fault. The problem could involve the ARD control unit, battery, charging circuit, wiring or connection with the elevator controller. Replacing the entire device without checking these components may lead to avoidable costs.
Before placing an order, record the following details:
- Existing model: Note the manufacturer's name, model number and product code.
- Power rating: Check the rating required by the installed elevator.
- Electrical requirements: Verify the voltage, phase and other specifications against the manufacturer's documentation.
- Controller compatibility: Confirm that the replacement supports the existing elevator control system.
- Battery details: Check the required voltage, capacity, number of batteries and terminal arrangement.
How to Choose the Right ARD Power Rating
Elevators have different motor ratings and control arrangements, so one rescue device will not suit every installation. The replacement must match the requirements of the existing system.
For example, an 11kW elevator ARD may suit an installation that requires this rating. However, the power rating alone does not confirm compatibility. A technician must check the electrical specifications, controller requirements and manufacturer's recommendations before approving the model.
When choosing an automatic rescue device supplier UAE, compare the available models, power ratings and technical specifications before selecting a unit for your elevator. Bestech Parts offers several automatic rescue devices for different power requirements, including:
- ARD-4007-3P: 7kW
- ARD-4011-3P: 11kW
- ARD-4015-3P: Model listed; confirm its full specifications before ordering.
- TMR ARD 3P-7.5KW 380V (TF): 7.5kW, 380V
- TMR ARD 3P-11KW 380V (TF): 11kW, 380V
- HH ARD 3P-15KW 380V (TF): 15kW, 380V
- TMR ARD 3P-18KW 380V (TF): 18kW, 380V
- HH ARD 3P-22KW, 30KW, 37KW and 45KW (TF): Models listed with ratings of 22kW, 30kW, 37kW and 45kW respectively.
Other listed options include TMR-ARD-3P-15KW, TMR-ARD-3P-45KW, HH-ARD-18.5KW, Inovance ARD 3P 7.5KW and Rescue Device MCTC-ERB-A1.
Confirm the exact product specifications, compatibility and current availability with the supplier before ordering.
Choosing the Right Backup Battery
Replacing an ARD without checking its battery can leave the emergency system unreliable. Batteries lose capacity as they age, and a battery that no longer holds sufficient charge might not provide the required backup during a power failure.
The Bestech Parts range also contains these battery options:
- Battery 12V 7Ah: 12V voltage, 7Ah capacity
- Battery 12V 9Ah: 12V voltage, 9Ah capacity
- Battery 12V 12Ah: 12V voltage, 12Ah capacity
For elevator ARD battery replacement in the UAE, compare the available battery options and confirm the required voltage, capacity and terminal configuration before ordering.
Check the ARD manufacturer's requirements, battery dimensions, terminal type and charging compatibility. If the system uses multiple batteries, a technician should confirm the required configuration and replace them according to the manufacturer's instructions. A higher-capacity battery is not automatically a suitable substitute for the original one.
When Should an ARD or Battery Be Replaced?
The right replacement depends on the fault identified during inspection. A battery might need changing if it fails a capacity test, cannot hold sufficient charge or no longer meets the manufacturer's service requirements.
A complete ARD replacement may be necessary when the control unit has failed, suitable replacement components are unavailable or the device continues to malfunction after diagnosis. The technician should determine whether the fault can be resolved through component replacement or requires a new unit.
Regular elevator ARD maintenance helps maintenance teams identify problems before an emergency occurs. Inspections should cover battery condition, charging circuits, electrical connections, fault indicators and rescue operation, following the manufacturer's instructions.
Keep records of inspection dates, battery changes, reported faults and test results. These records help technicians identify recurring problems and plan future maintenance.
Finding a Lift Spare Parts Supplier in the UAE
When sourcing a replacement, provide the supplier with the existing model number, nameplate details, power rating and clear photographs of the unit. This information helps the team identify a suitable match and check whether the required product is available.
A lift spare parts supplier in the UAE should provide relevant product information and clarify availability and delivery arrangements. Ask for technical documentation when needed, particularly if the original model is discontinued or an alternative is being considered.
Before confirming the order, compare the proposed replacement with the existing installation requirements. Do not assume that two devices with the same power rating are interchangeable. Have a qualified elevator technician verify any alternative model before purchase.
Final Checks Before Installation
Before approving an elevator ARD replacement in the UAE, compare the selected device and battery against the elevator manufacturer's requirements. Check the model number, electrical specifications, battery configuration and controller compatibility.
Installation and wiring should be completed by qualified elevator personnel using the approved procedure. After installation, the technician should test the rescue sequence, verify the system's operation and document the results. The elevator should be returned to service only after the required checks have been completed.
Choosing compatible parts and maintaining clear service records helps keep the rescue system ready for a power interruption.
