What is MCP in fire alarm system?

In a fire alarm system, MCP stands for Manual Call Point. Here's a detailed explanation:

Manual Call Point (MCP)

• Purpose: A device that allows individuals to manually trigger the fire alarm system when a fire is detected, ensuring rapid alerting even if automatic detectors (e.g., smoke or heat detectors) haven't yet activated.

• Design: Typically a red box mounted on walls in easily accessible locations (e.g., near exits, corridors). Activation often involves breaking a glass panel or pressing a button.

• Function: When activated, it sends a signal to the Fire Alarm Control Panel (FACP), which then sounds alarms (e.g., sirens, strobes) to evacuate the building.

• Standards: Required by fire safety codes globally (e.g., NFPA, EN 54) to ensure prompt human intervention in emergencies.

Key Features:

• Break-glass mechanism or push-button design.

• Tamper-proof and clearly labeled for emergency use.

• Often includes a test key for maintenance.

Why It Matters:

MCPs are critical for early warning, enabling occupants to act quickly before automated systems detect the fire, potentially saving lives and reducing property damage.
