What Is a Manual Call Point? Fire Alarm Pull Stations
Answer: A manual call point (MCP) — called a “pull station” or “manual fire alarm box” in the US — is a wall-mounted device that lets a person manually trigger a building’s fire alarm by breaking a glass cover or pulling a lever, rather than waiting for an automatic detector to sense smoke or heat. It sends a signal directly to the fire alarm control panel, which then activates sirens, strobes, and any connected suppression or evacuation systems throughout the building.
What is a manual call point? A manual call point (MCP) — called a “pull station” or “manual fire alarm box” in the US — is a wall-mounted device that lets a person manually trigger a building’s fire alarm by breaking a glass cover or pulling a lever, rather than waiting for an automatic detector to sense smoke or heat. It sends a signal directly to the fire alarm control panel, which then activates sirens, strobes, and any connected suppression or evacuation systems throughout the building.
How Does a Manual Call Point Work?
Inside every manual call point sits an electrical circuit that stays open under normal conditions. Breaking the glass cover (or pulling the lever on frangible-element models) closes that circuit, and the device sends a signal to the fire alarm control panel almost instantly. The panel then triggers building-wide sirens and strobes and, depending on the system design, can also trip elevator recall, close fire doors, or release door-holding magnets — all within seconds of activation.
This manual layer exists precisely because automatic detectors, however reliable, still need smoke or heat to physically reach the sensor before they respond. A person who spots a fire visually can trigger the alarm the moment they see it — often faster than an automatic detector several meters away would react.
Manual Call Point Types
Not every manual call point is built the same way, and the differences matter for both compliance and system design.
Direct-Operation (Type A) vs Indirect-Operation (Type B)
Under EN 54-11, the European standard governing manual call points, devices fall into two categories: Type A operates directly — breaking the glass immediately triggers the alarm — while Type B requires an additional deliberate action, such as pressing a button after breaking the cover, adding a small extra step that reduces accidental activations.
Conventional vs Addressable Call Points
Conventional call points report which circuit (zone) triggered an alarm, but not the exact device. Addressable call points report their own unique identifier to the panel, so the control system can pinpoint the exact floor and location instantly — a meaningful advantage in large or multi-story buildings where every second of search time matters.
Color Coding: Red vs Green
Red call points are the standard fire alarm activation device found throughout a building. Green call points serve a different function entirely — they’re installed next to emergency exits to manually release electromagnetic door locks during an evacuation, and shouldn’t be confused with a fire alarm trigger.
ATEX / Explosion-Proof Call Points for Hazardous Areas
Standard call points aren’t safe everywhere. In facilities with explosive gas, vapor, or dust atmospheres — refineries, chemical plants, grain mills — a standard call point’s internal spark risk becomes a genuine ignition hazard. ATEX-certified (explosion-proof) manual call points are built to the same Ex d, Ex e, or Ex i protection principles used across other hazardous-area equipment, ensuring the device itself can’t become the ignition source it’s meant to help prevent.
Where Are Manual Call Points Required?
Fire codes typically require manual call points along escape routes, near exits, and at stairwell landings — positioned so that no occupant needs to travel more than a defined maximum distance (commonly around 30 meters, though this varies by code and occupancy type) to reach one. They need to sit at a consistent, easily reachable height and remain visually unobstructed at all times; a call point blocked by furniture or signage defeats the entire point of having one.
Standards That Govern Manual Call Points
In Europe and Türkiye, manual call point design and performance requirements are set by EN 54-11, part of the broader EN 54 fire detection and alarm systems standard series. In the US, the equivalent requirements sit within NFPA 72: National Fire Alarm and Signaling Code, which governs manual fire alarm boxes as part of the overall fire alarm system. Facilities operating internationally, or supplying multiple markets, often need equipment certified to both standards.
Maintenance and Testing
Manual call points are tested as part of a building’s overall fire alarm system maintenance, typically through a combination of a weekly functional test (usually via a test key that doesn’t require breaking the actual glass) and a more comprehensive annual inspection carried out by a certified technician. A call point that’s painted over, physically damaged, or blocked from view can fail exactly when someone needs it most — which is why visual condition checks matter just as much as electrical function tests.

Frequently Asked Questions
What's the difference between a manual call point and a pull station?
Nothing functionally — they’re the same device under different regional names. “Manual call point” is the standard European/international term, while “pull station” (or “manual fire alarm box”) is the common US term used under NFPA 72.
What's the difference between a manual call point and a smoke detector?
A smoke detector triggers automatically once it senses smoke, without human involvement. A manual call point requires a person to physically activate it after spotting a fire, which means it can sound the alarm even before an automatic detector would react, or if the automatic system has failed.
Do manual call points need to be ATEX certified?
Only in areas with an explosive gas, vapor, or dust atmosphere — refineries, chemical plants, and similar facilities. Outside of hazardous areas, a standard (non-ATEX) call point meeting EN 54-11 or NFPA 72 is sufficient.
What happens if someone presses a manual call point by accident?
Type B call points, which require an extra deliberate action beyond breaking the cover, are specifically designed to reduce accidental activations. If a false alarm does occur, building management typically verifies the situation and resets the panel; frequent false alarms usually signal a fault worth investigating.
How far apart should manual call points be installed?
Fire codes generally require that no occupant travel more than a set maximum distance — often around 30 meters, though the exact figure depends on the applicable code and building occupancy — to reach the nearest call point. Local code should always be consulted for the specific requirement.
