Very Early Fire Detection. Engineered for Critical Environments.
An Chi Pte Ltd delivers advanced fire-detection solutions built around Securiton's proven SecuriSmoke aspirating smoke detection technology. Based in Singapore, we supply and export Securiton fire-detection equipment across Asia, with particular focus on China and Southeast Asia.
Detect Earlier. Respond Faster. Protect What Matters.
Conventional fire detection often depends on smoke reaching a detector. Aspirating smoke detection takes a more proactive approach: air is continuously drawn from the protected area through a network of sampling pipes and analysed by highly sensitive smoke sensors. This enables increases in smoke concentration to be identified at a very early stage, creating more time to investigate and respond.
- Very early warning for mission-critical environments.
- Flexible sampling-pipe layouts for rooms, raised floors, ceilings, cabinets and difficult-to-access areas.
- Highly sensitive, robust detection with automatic soiling compensation on applicable SecuriSmoke models.
- Solutions suitable for data centres, clean rooms, power facilities, warehouses, archives and other demanding applications.
How Aspirating Smoke Detection Works
- 01
Sampling
Air is continuously drawn from the protected area through a network of sampling pipes.
- 02
Analysis
A high-performance fan draws air into an evaluation unit with highly sensitive smoke sensors.
- 03
Monitoring
Airflow monitoring checks sampling pipes for breakage and apertures for soiling.
- 04
Response
Multiple pre-signal and alarm levels provide early warning and time to respond.
Swiss Fire-Detection Technology. Regional Project Support.
Securiton AG was established in 1948 and forms part of the Swiss Securitas Group. Its international fire-protection portfolio combines proprietary technology, in-house research and development, German production and specialised expertise in demanding fire-detection applications.
