In the case of modern constructions, the car operating panel (COP) in the elevator is much more than just a panel with numbers to choose the destination floor. As a point of contact between the passenger and the lifting device, the elevator button panel becomes an important center of security during both regular operations and emergency situations. It contains not only the switches but also a complex set of safety measures of electrical and mechanical nature.
1. Emergency Alarm Features on the Elevator Button Panel
In case of any unscheduled breakdown, the emergency communication system integrated into the elevator button panel comes to the rescue, forming a comprehensive rescue pathway.
- Alarm Buzzer Activation: On pressing the alarm button—having a yellow bell sign—the buzzer, which emits sound between 80 dB and 90 dB, is activated, situated on the top of the elevator cabin and in the hoistway itself.
- Hands-Free Microphone and Speaker: Adhering to ASME A17.1 and EN 81-28 codes, the elevator button panel is installed with a hands-free microphone and speaker. Pressing the button for 3 to 5 seconds connects you either to the security room or the 24/7 rescue center.
- Visual Status Signals: To assist hearing-impaired riders and reduce panic, modern panels include dual-color illuminated icons. A yellow light signals a dispatched call, while a green light confirms active two-way voice communication.
2. Fireman’s Service Controls on the Elevator Button Panel
During a fire, standard passenger control is overridden, and the elevator button panel shifts into specialized firefighter service modes.
Phase I Emergency Recall
When smoke or heat detectors register a hazard, the elevator button panel immediately cancels active destination calls and disables hall buttons. The car travels directly to a designated recall floor, parks with its doors open, and prevents public entry into the shaft.
Phase II Emergency In-Car Operation
Firefighters insert a key into the dedicated “Fireman’s Switch” on the elevator button panel and turn it to “ON” for absolute manual control:
Continuous Pressure Door Commands
Automatic door movement is suspended. Firefighters must hold down the “Door Open” or “Door Close” button continuously. Releasing the button instantly stops or reverses door movement to prevent accidental exposure to heat or smoke.
Call Cancel Functionality
The panel’s “Call Cancel” switch allows rescue crews to erase registered floor selections immediately if safety conditions change on a target floor.
3. Emergency Stop and Door Safety Mechanisms on Elevator Button Panels
Because door management and unexpected movements account for many service calls, panel response mechanisms operate with extreme precision.
- Emergency Stop Switch: The industrial panel, as well as the heavy-duty freight panel, comprises an emergency stop switch represented by the red mushroom-shaped “Emergency Stop” switch. Pressing this switch will open up the safety circuit and activate the mechanical brakes to stop the car movement after 0.5 seconds.
- Anti-Pinch Door Open Controls: The “Door Open” switch on the elevator control panel works together with infrared light curtains. If an obstacle larger than 5 mm interferes with the entrance detection field, then pressing the door open button on the control panel will cancel the door closing operation.
- Door Hold Delays: Medical and freight applications have a door hold button on the panel that holds the door open for between 30 seconds and 180 seconds.
4. Physical Protection and Vandal-Resistant Elevator Button Panels
The physical strength of the elevator button panel dictates how reliable it is in severe or abusive conditions.
Highly congested transit stations, business places, and factories need unique methods of construction:
- Industrial-Grade and Split Configurations: For environments exposed to heavy dust, moisture, or impacts, the GOTS-Split Type Elevator Operating Panel offers a specialized solution. Its split architecture isolates sensitive electronic wiring from high-impact zones, utilizing IP54-rated seals to keep airborne particles and grease away from contact blocks.
- Integrally Reinforced Stainless Steel Assemblies: In commercial towers where structural strength must blend with clean design, the GOTS-Stainless Steel Car Operating Panel exemplifies high-end protective engineering. Crafted from single-piece 304 or 316 stainless steel plates (2.0 mm to 3.0 mm thick), it meets EN 81-71 Class 2 anti-vandal standards to withstand severe impacts and flame contact.
- Protection against Ingress and Liquids: To guard against liquid ingress while cleaning the panel, rubber gaskets and silicone O-rings are fitted around the button rims, thereby providing an IP65 rating.
5. Accessibility and Backup Power Features on Elevator Button Panels
Universal design standards and power-loss redundancies complete the safety architecture of modern elevator button panels.
Accessibility Rules for ADA and EN 81-70
Accessibility rules require all elevator button panels to be reachable, with their maximum height limited to 1220 mm (48 inches) from the cabin floor. All the buttons have Grade 2 Braille writing and tactile letters, which are not less than 0.8 mm high.
Emergency Lighting System
In the case of electricity outages in the building, an emergency 12V battery, located behind the elevator button panel, becomes operational in less than 1 second. It allows powering the emergency light to be powered with enough brightness (at least 5 Lux) for more than 60 minutes.
สรุป
A fully compliant elevator button panel represents a convergence of electrical engineering, accessible design, and durable physical protection. From alarm communication and firefighter override controls to anti-vandal materials and backup lighting, every component plays a crucial role in passenger protection.

คำถามที่พบบ่อย
Q1: What does pressing the emergency alarm button on the elevator button panel do?
A: Once this button is pressed, an external horn installed on the top of the car will immediately ring, and an automatic two-way intercom call will be established to either the security desk or offsite dispatch center.
Q2: Why are Braille and raised characters mandatory on elevator button panels?
A: Braille and tactile characters are required by ADA and EN 81-70 standards to ensure visually impaired individuals can independently and safely identify floor numbers, alarm buttons, and door controls through touch.
Q3: What is the main purpose of the fireman’s service keyhole on an elevator button panel?
A: The keyhole enables first responders to override automated elevator behavior during fires. Turning the key switches the panel to Phase II mode, disabling external hall calls and placing complete manual control of travel and doors in the firefighters’ hands.
Q4: How long will the emergency lights on the elevator button panel work in case of power failure?
A: According to the codes, the battery backup system must provide enough emergency lighting (minimum 5 Lux) and supply energy to the communication system for at least 60 minutes after the failure of the main power supply.
Q5: What kind of IP rating is needed for the elevator button panel in industrial applications?
A: In the case of freight elevators, outdoor elevators, or places where there is regular washing and dust, an IP rating between 54 to 65 is highly recommended for the elevator button panel.
