High-performance backup power supply for mains failure which is ideal for Firefighting Lifts. Energises the elevator for a large number of trips during extended time enabling complete building evacuation.
Product is suitable for elevators or lifts in residential, commercial and industrial environments.
EN81-72 compliant and EN 81-76:2025 compliant secondary power supply solutions.
Out team of Engineers will determine the best cost-effective means to deliver power “on demand” to a dedicated evacuation lift in an emergency when normal operations are not possible.
This high-performance auxiliary supply system keeps the elevator running for hundreds of trips without mains. The system keeps the controller informed at every moment about the charge level of the batteries.
The installation is very simple, even for existing elevators with no additional cabling to floors.
Our team will work with you to fully understand your requirements and provide the correct size unit for the particular elevator.
Product advantages:
EN81-76 and EN81-72 and BS9999 compliant.
Fully customisable (trips, 1,2,3,4 hours...).
Fully integrates with existing & new controller.
ATS included.
Energy regeneration.
BMS interface.
Supercapacitor powered - conversion systems.
Simple connection and easy adaptation to any lift, even for modernization.
The elevator controller keeps full control of the system and the elevator (no additional control is required).
48 V battery pack for all models with a constrained size and easy and low-cost maintenance.
Regenerative. Recovers the energy generated by the elevator and stores it in the batteries thus expanding the duration of the evacuation time.
Suitable for new and existing installations.
What is included:
Auxiliary supply for mains failure, providing:
- 600 Vdc for the VF drive.
- 230 Vac for controller, brakes, door operators, etc.
Low power input to maintain the accumulator fully charged.
48 V batteries, similar for all models. Low cost and low maintenance. The system provides information to the controller about the charge level during the complete evacuation process.

EN81-76:
The British Standards Institute has launched a new European Standard that provides a framework for the safe evacuation of persons with disabilities using lifts during emergencies, such as fires. It introduces a more inclusive and technically advanced approach to evacuation planning, with direct implications for building design, lift specification, and operational strategy.
Conventionally, evacuation lifts were used only with the assistance of trained staff, as outlined in BS 9999.
BS EN 81-76 expands this by defining three operational modes for evacuation lifts, offering more flexible emergency responses:
Assisted evacuation (conventional): A trained person (lift car driver now referred to as driver assisted) assists individuals with disabilities during evacuation.
Automatic evacuation: The lift operates normally to transport people to safety, without needing a driver.
Remote-controlled evacuation: A trained operator controls the lift remotely to facilitate evacuation.
These new modes of operation are designed to improve occupier safety during emergencies, especially in buildings where staff may not always be present or immediately available EN 81-76 provides technical and operational requirements for building designers, facility managers, and emergency planners to implement these systems effectively.
Key points that lift companies and building owners/managers should be aware of:
Insufficient Power Supply Provisioning: Errors in applying or omitting secondary power supply requirements could compromise lift functionality during an evacuation.
Misalignment with Fire Strategy: Inadequate alignment of the evacuation lift specifications with the building’s fire and evacuation strategy could result in non-compliance and incorrect lift classification (Class A or B).
Space Limitations in Shaft and Car: Inadequate shaft dimensions may hinder compliance with essential requirements, such as minimum car size and trap door dimensions.
Complex Compliance Requirements: BS EN 81-76 outlines intricate operational requirements for each evacuation mode, necessitating advanced systems for communication, control logic, signal prioritisation, and the suspension of normal operations.
Lack of Inclusive Evacuation Planning: Insufficient planning for the evacuation of individuals with reduced mobility, particularly backup procedures in case of lift failure, presents significant safety, operational, and regulatory challenges.
Unaddressed Environmental Hazards: Inadequate measures against water ingress (e.g., from firefighting or sprinkler discharge) could render the lift inoperable. This risk requires mitigation through effective design solutions, such as drainage systems or ramping.
