School Project
Introductions

This project installing a comprehensive fire and carbon monoxide safety early warning system for a 50-year-old German Mayly primary school. The school grounds cover approximately 62,902 square meters, with a building area of approximately 37,196 square meters, including teaching buildings, laboratories, a library, computer rooms, and other functional spaces.

To ensure the safety of all teachers and students in their daily activities, designed and installed a European EN 54 and international standards fire alarm system. The system uses 124pcs alarms (smoke alarms, heat alarms, CO alarms) and controllers. It enables early fire warnings, timely evacuation, and emergency response.

😔 Challenges

Complex Structure and Cable Renovation of the Old Building: The primary school is 50 years old, with few pre-buried conduits, making traditional wiring difficult and resulting in a large amount of cable laying work.
Diverse Functional Spaces and High Population Density: Different rooms have different risk characteristics and population densities, requiring accurate classification of protection levels to prevent omissions and avoid false alarms.
False Alarms and Maintenance Management: Daily activities in the school (kitchen smoke, laboratory gases, vapors generated from experiments, etc.) may trigger false alarms, requiring appropriate equipment selection and intelligent deployment.

☺️ Solutions

Develop a Detailed Construction Plan: Use on-site survey data to develop a detailed wiring diagram, prioritizing wireless connections and pre-embedded conduits in the ceiling to minimize structural damage.
Zonal Installation Design: Divide rooms according to function, installing smoke detectors or combined smoke/CO detectors in classrooms and corridors, and heat alarms in areas with significant temperature changes or less noticeable smoke， install combined smoke/CO detectors in gas boiler rooms, etc.
False Alarm Control and On-site Commissioning: Conduct an on-site risk assessment before installation and negotiate a false alarm tolerance mechanism with the logistics teachers and school security, conduct system commissioning after installation, incorporate time delays or tiered alarm designs for scenarios with multiple fire sources, such as kitchens and laboratories.

How Many Alarms

Explore how different areas are equipped with the appropriate types and number of alarms, ensuring effective fire safety across various environments.

Smoke Alarms

Following EN 54 standard (applicable to Europe): The coverage area and detector spacing for each detector are standardized. For example, a point detector can cover approximately 80-100㎡ on a flat roof, depending on the ceiling height and interior layout.

teaching building

30 Classrooms + 1 Special Education Room + 1,000㎡ Corridors

One smoke alarm per classroom at least, based on an average classroom area of 60 m²
One smoke alarm per 80 m² in corridors and common areas.

MULTI-FUNCTIONAL building

Laboratories + Library + Computer Rooms, etc. (Total area: 5,000 m²).

High-occupancy areas (libraries, reading rooms ): one smoke alarm per 80 m².
High-risk areas (Laboratories): one smoke alarm per 60 m², or based on exit distance.

This project used total 103 pcs smoke detectors, the details are as follows:

80pcs SM11R4 Wireless Interconnected Smoke Alarm
10pcs SM21 Hardwire Smoke Alarm with DC3V backup Battery
13pcs CS11R Wireless Interlinked Smoke And Carbon Monoxide Combo Detector

Heat Alarms

2 Boiler rooms + 5 Electrical Rooms + 1 Kitchen.

The project used total 13 pcs heat alarms, the details are as follows:

Choose The Right Alarms For School

Based on the school’s spatial type and risk characteristics, the project will achieve fire (smoke/temperature rise) detection in all critical areas within the school and CO detection and early warning in areas where carbon monoxide leaks may occur (such as boiler rooms and machine rooms), so the project used three type alarms:
