Emergency Break Glass 

1. Introduction

An Emergency Break Glass unit is a manual safety device that allows users to trigger emergency alarms, unlock doors, or deactivate security systems by breaking a small glass panel. It plays a crucial role in fire safety, access control, and emergency evacuation protocols.

This device is widely used in:
✔️ Fire alarm activation points
✔️ Access control override systems
✔️ Elevator emergency stop buttons
✔️ Emergency door release mechanisms
✔️ Industrial and high-security environments

Emergency break glass units ensure quick action in life-threatening situations, providing an instant solution for emergency responses.

2. Key Features of the Emergency Break Glass Unit

✅ Instant Emergency Activation

• Triggers alarms or unlocks doors immediately upon breaking the glass.

✅ Durable & Tamper-Resistant Design

• Constructed with shatter-proof or tempered glass for controlled breaking.

✅ High Visibility & Easy Identification

• Marked with clear labels and bright colors (typically red or green) for quick recognition.

✅ Multiple Functions (Fire, Access Control, Security Systems)

• Works for fire alarms, electronic door releases, security shutdowns, and more.

✅ Resettable & Replaceable Glass Options

• Some models allow for quick reset without replacing the glass.

✅ Weatherproof & Vandal-Resistant Options

• Available in IP-rated enclosures for outdoor and industrial environments.

3. How the Emergency Break Glass Unit Works

Step 1: Identifying an Emergency

• During a fire, unauthorized lockout, or security breach, the user locates the break glass unit.

Step 2: Breaking the Glass Panel

• A light press or a small hammer (if provided) breaks the glass, activating the internal switch.

Step 3: Emergency Activation

• Depending on the system, breaking the glass will:
  🔹 Trigger a fire alarm
  🔹 Release an electronic door lock
  🔹 Shut down security systems

Step 4: System Reset & Glass Replacement

• After the emergency, the unit is reset by replacing the glass or resetting the switch.
