The 3MK-FCE EXIT Stopper Door Alarm is an advanced security solution designed to prevent unauthorized use of emergency fire exit doors while ensuring easy and authorized access during real emergencies. Engineered for retrofit compatibility, this compact, easy-to-install device delivers powerful protection with a loud 85 dB siren and key-switch override functionality, making it ideal for commercial, industrial, and institutional environments.
Certified Performance and User-Friendly Design
Powered by 12V DC, the 3MK-FCE features a high-decibel alarm that activates immediately upon unauthorized door use. The unit can be seamlessly mounted on single exit doors and provides audible warnings to alert nearby personnel. For legitimate exits, a secure key-operated override allows users to deactivate the alarm without triggering unnecessary alerts.
Versatile and Expandable Security Functionality
Designed for seamless integration, the 3MK-FCE connects effortlessly with third-party systems such as fire and intrusion alarms, expanding your existing security infrastructure. In addition, its built-in audible reminder system prevents operational oversights by warning users if the alarm is left deactivated for more than five minutes.
Reliable, Responsive & Ready for Action
With intelligent design and professional-grade components, the 3MK-FCE combines simplicity and sophistication in one compact package. Whether securing a retail store, hospital exit, or warehouse fire door, it offers powerful deterrence without compromising ease of use.
Key Features & Benefits
Loud 85 dB Alarm Output
Delivers a piercing sound to instantly alert of unauthorized use of emergency exit doors.
Secure Key-Switch Operation
Enables authorized personnel to disable or enable the alarm as needed, ensuring controlled access during emergencies or service.
Auto-Reminder Audible Warning
Integrated feature activates if the key is left in the OFF position for over 5 minutes, ensuring security isn’t unintentionally compromised.
Third-Party System Compatibility
Easily integrates with fire and intrusion alarm systems via NO/NC voltage-free contacts, creating a unified security solution.
Quick & Easy Installation
Compact design suitable for retrofit applications; installable in minutes on virtually any single emergency door.
How It Works:
1- Standby Mode (Key OFF Position)
When the key-switch is turned to the "Key OFF" position, the alarm system is deactivated. In this state, authorized personnel can open the emergency exit door without triggering the alarm.
2- Armed Mode (Key ON Position)
Turning the key-switch to the "Key ON" position activates the alarm system. Now, if the emergency exit door is opened, an 85 dB audible alarm is instantly triggered to alert nearby individuals.
3- Alarm Triggered on Unauthorized Access
While in "ON" mode, any unauthorized or unexpected door opening causes the built-in siren to sound, serving as a strong deterrent against theft, intrusion, or safety violations.
Authorized Bypass with Key-Switch
If authorized staff need to use the exit door, they can disable the alarm temporarily by turning the key-switch to the "OFF" position, preventing unnecessary alerts during legitimate use.
Audible Reminder After 5 Minutes
To prevent oversight, if the key-switch remains in the "OFF" position for more than 5 minutes, a distinct reminder tone is automatically activated to prompt users to reactivate the system.
Seamless System Integration
The system can be linked with fire alarm or intrusion systems using voltage-free NO/NC output contacts, providing additional security layers in larger setups.
Technical Advantages
-
Integrated Key-Switch Operation
Unlike standard door alarms that rely on basic reset buttons, the 3MK-FCE features a dedicated key-switch control, allowing only authorized personnel to activate or deactivate the system—ensuring higher security and access control.
-
Auto Reminder Function After 5 Minutes
A unique built-in timer constantly monitors the key-switch status. If left in the "OFF" position for over 5 minutes, a distinct warning sound reminds users to reactivate the system—minimizing the risk of human error and long-term disarming.
-
Dual NO/NC Output Terminals
While most models offer limited integration, the 3MK-FCE is equipped with two jumper-selectable NO/NC relay outputs, allowing seamless integration with fire alarms, intrusion systems, or access control setups.
-
Compact Yet Powerful
Despite its slim and compact design, the device delivers a loud 85 dB alarm, ensuring it grabs immediate attention—ideal for retrofit installations where space is limited but effectiveness is critical.
-
Rapid Installation & Retro-Fit Friendly
The unit is designed for quick mounting, making it perfect for existing buildings or facilities that require enhanced exit monitoring without complex rewiring or upgrades.
