Library Project
Introductions

This project installs a comprehensive fire safety early warning system for French Public Library in Pairs.There are nearly 50,000 books in approximately 800 square meters library and 6 functional area including a book area, a children’s reading area, an electronic reading room, a training room, a multi-purpose room, and a local history archive etc. It is open to the public for 10 hours per day and 100 visitors come here. There is a typical high-risk commercial service establishment for its diverse functional spaces and high volume of people.

Referring to the building’s functional layout and operational requirements and product types and technical characteristics, the project is comprehensively designed and planned the fire detection and alarm system with EN14604 &EN50291 fire safety regulation for this library. The system uses 21pcs alarms (smoke alarms, heat alarms, CO alarms) and controllers. It enables early fire warnings, lower false alarms, timely evacuation, easy maintenance and emergency response in the initial fire or carbon monoxide leak stage and simultaneously gives the information to the library management.

😔 Challenges

High fire security risks of with books and papers: About 50,000 flammable books, newspapers, and magazines easily have a fire and spread extremely quickly in its initial stage, the system should early detect but low false alarm.
Differences Functional Spaces: Various people go to different functional spaces such as children’s reading rooms, electronic reading rooms, and multi-functional rooms and may make false alarms or missed alarms.
Different Factors Causing False Alarms: Dust, air conditioning ventilation, and other interfering factors easily make false alarms in quiet library environments.

☺️ Solutions

Differentiated detection technology Combination together: Different types of detectors are used in different areas: Photoelectric smoke detectors are used in reading and book storage areas.
Heat alarms are prioritized for installation in visible fire areas where smoke may easily cause false alarms.
Smoke and CO alarms combination are used to avoid the limitations of a single detection technology.
False Alarm Resistance Design Logic: The engineers optimize MCU multi-parameter alarm signal and algorithm to filter environmental noise and photo sensor sensitivity to reduce false alarm.
Double Verification of Installation and Commissioning: Each Alarm installing location on ceilings or high walls and avoiding near ventilation openings, air conditioning vents, should have the cross-verification for installation height, airflow impact, and measured response time.

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.
Entrance/exit + Lobby area + Children’s reading room + Electronic reading room + Multi-purpose room + Local history archive + Corridors

This project used total 16 pcs smoke detectors, the details are as follows:

3pcs CS13R Wireless Interlinked Smoke And Carbon Monoxide Combo alarms for entrance and lobby area
2pcs CS13R Wireless Interlinked Smoke And Carbon Monoxide Combo alarms for children’s reading room
2pcs CS13R Wireless Interlinked Smoke And Carbon Monoxide Combo alarms for electronic reading room
2pcs CS13R Wireless Interlinked Smoke And Carbon Monoxide Combo alarms for multi-purpose room
3pcs CS13R Wireless Interlinked Smoke And Carbon Monoxide Combo alarms for local history archive
4pcs CS13R Wireless Interlinked Smoke And Carbon Monoxide Combo alarms for corridors and entrance/exit

Heat Alarms

1 Computer room

The project used total 2 pcs heat alarms, the details are as follows:

2pcs Wireless Interlinked heat alarms HD11R

Heat alarms are installed in visible fire areas where smoke may easily cause false alarms.
Normally 2pcs heat alarms per computer room.

CO Alarms

Boiler rooms + Gas Equipment Rooms + Underground parking

The project used total 3 pcs heat alarms, the details are as follows:

3pcs CS13R Interlinked Smoke and Carbon Monoxide Combo Detector

At least 1pcs CO detector per equipment room, with horizontal distribution across multiple floors.

Choose The Right Alarms For Library

Based on the library’s spatial type and risk characteristics, the project will achieve fire (smoke/temperature rise) detection in all critical areas within the library 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:
