Sigma Elevators is a trusted manufacturer of elevators and elevator safety systems, serving residential, commercial, and industrial clients across India.
Passenger safety inside an elevator depends entirely on the quality and reliability of its safety systems. A single weak component in the safety chain can create serious risk. At Sigma Elevators, every Elevator Safety Device we manufacture goes through strict quality checks before installation. We do not source these components externally — we build them ourselves, which gives us full control over performance and reliability at every stage.
Our Elevator Safety Devices — What We Manufacture
1. Integrated Control System
The Integrated Control System is the operational brain of the elevator. It manages floor calls, door operations, motor commands, and inter-device communication from a single panel. A well-engineered control system reduces the chance of conflicting commands and keeps every component operating within its defined parameters. Our Integrated Control System is designed for compatibility across different elevator configurations — passenger lifts, goods lifts, and hospital elevators — making it a versatile core component in any installation.
2. Microprocessor Control
The Microprocessor Control unit handles real-time processing of all elevator commands and feedback signals. It monitors operational data continuously — speed, floor position, door status, load — and adjusts the elevator's response accordingly. This level of processing accuracy reduces mechanical wear, improves ride quality, and triggers protective shutdowns when any parameter moves outside safe limits. As an Elevator Safety Devices Manufacturer, we integrate the Microprocessor Control with other safety components so they all communicate through a single, coordinated system.
3. Automatic Rescue Device (ARD)
A power failure should never trap passengers inside an elevator cabin. The Automatic Rescue Device activates immediately when mains power is lost. It uses stored battery power to drive the elevator to the nearest floor, open the doors, and allow passengers to exit safely. The ARD operates automatically without any manual intervention — which is critical because building staff may not always be immediately available during a power cut. This device is one of the most practically important Elevator Safety Devices in everyday commercial operation.
4. UPS A.R.D. System
The UPS A.R.D.By offering a more reliable power backup configuration, the system expands the capabilities of the Automatic Rescue Device.. While a standard ARD handles basic rescue operations, the UPS A.R.D. System supports the elevator's control and lighting circuits during extended power outages. This is particularly relevant for buildings in areas with frequent or prolonged power interruptions, where a basic ARD battery may not be sufficient to cover the full outage duration.
5. Infrared Curtain Sensor
The Infrared Curtain Sensor is installed across the elevator door opening. It creates an invisible grid of infrared beams that detect any object or person in the door's path. If any beam is interrupted while the door is closing, the door immediately reverses — preventing injury to passengers entering or exiting. This is especially important in high-traffic installations — shopping malls, hospitals, offices — where doors are constantly in use. Our Infrared Curtain Sensors are calibrated for fast response and reliable detection across the full height of the door opening.
6. AC Control Drive
The AC Control Drive manages the elevator motor's speed and torque throughout each journey — from start to stop. Smooth acceleration, controlled travel speed, and gradual deceleration are all managed by this device. Beyond ride comfort, the AC Control Drive plays a direct safety role. It prevents sudden starts and stops that place mechanical stress on cables, brakes, and guide systems. Controlled motor operation also means more predictable behaviour under varying load conditions.
7. Overload Sensor
The Overload Sensor monitors the total weight inside the elevator cabin. When the load exceeds the rated capacity, the sensor prevents the doors from closing and activates an audible alert, prompting passengers to step out until the load is within safe limits. This protects the mechanical components — motor, cables, and brakes — from operating beyond their design ratings, and directly prevents overloading situations that could compromise safety.
8. Emergency Alarm
The Emergency Alarm gives trapped passengers a direct way to call for help. Installed inside the cabin, it connects to a building management point or an external monitoring station. When activated, it sends an alert so that the appropriate personnel can respond promptly. In combination with emergency lighting — which activates on battery power during a power failure — the Emergency Alarm completes the passenger communication safety layer in our Elevator Safety Devices range.
Compliance and Documentation
All Elevator Safety Devices manufactured by Sigma Elevators comply with Bureau of Indian Standards requirements for passenger and goods lifts. Every device is supplied with test records, calibration data, and compliance certificates needed for building approvals and occupancy clearances. As an Elevator Safety Devices Manufacturer in Gujarat, we actively support clients through the inspection and certification process — not just the equipment supply.
Maintenance of Safety Devices
Installed safety devices need periodic testing and servicing to confirm they will perform correctly when activated. Our maintenance teams carry out:
- ARD and UPS A.R.D. battery and activation tests
- Infrared curtain sensor calibration checks
- Overload sensor accuracy verification
- Control system diagnostic reviews
- Emergency alarm response testing
Maintenance is built into our service agreements as a standard requirement — not an optional extra.

Frequently Asked Questions
What Elevator Safety Devices does Sigma Elevators manufacture?
We manufacture eight core devices — Integrated Control System, Microprocessor Control, Automatic Rescue Device, UPS A.R.D. System, Infrared Curtain Sensor, AC Control Drive, Overload Sensor, and Emergency Alarm — all produced in-house at our Gujarat facility.
What is the difference between an ARD and a UPS A.R.D. System?
The standard ARD activates on power failure to bring the elevator to the nearest floor and open the doors. The UPS A.R.D. System provides a more comprehensive power backup that also supports the elevator's control and lighting circuits during longer outages.
How does the Infrared Curtain Sensor protect passengers?
It creates a grid of infrared beams across the door opening. Any obstruction — a person, luggage, or any object — interrupts the beams and immediately reverses the closing door, preventing injury.
Are your Elevator Safety Devices compliant with Indian standards?
Yes. All devices comply with Bureau of Indian Standards requirements for passenger and goods lifts. We provide full documentation including test records and compliance certificates with every installation.
Does Sigma Elevators provide maintenance for safety devices after installation?
Yes. As a full-service Elevator Safety Devices Manufacturer in Gujarat, we offer scheduled maintenance programmes covering all safety devices — including ARD battery tests, sensor calibration, and control system diagnostics — across all our installations in India.
