High sensitivity fire alarm


According to the US NFPA 72 system design standard, there are goals when designing a fire alarm system:

  1. Objectives for the safety of human life.
  2. Asset protection goals.
  3. The objective of protecting business continuity.

Depending on the requirements set forth, the fire alarm system will be designed accordingly. With the category of smoke and heat detector fire alarm systems with sensitivity in Class C (Class C) are applied for the purpose of life safety and protection of property. With data centers, telecommunications systems, operators... the system requires continuous operation, must not be interrupted for any reason, so fire must be detected from very early stage before a fire occurs. High sensitivity called fire alarm system used for class A and B, applications.

High sensitivity fire alarm systems have many different names depending on the manufacturer such as HSSD (High Sensitivity Smoke Detector) or ASD (Aspirating Smoke Detector) or VESDA (Very Early Smoke Detection Apparatus).


High sensitivity fire alarm system is one of the systems that can warn as soon as possible about the possibility of a fire. The sensitivity and ability to accurately determine the fire address as well as give early notifications are superior to traditional models.

The table compares the advantages and disadvantages of High sensitivity fire alarm systems and fire alarm tradition.

With outstanding features when detecting its invisible hazards, the extremely sensitive environmental monitoring system VESDA is suitable for locations containing high-value electronic components and assets such as:

+ Data center…                                                          + Air-Change …

+ High ceilings, Stores…                                            + Challenging/Aggressive Environments

+ Aesthetics …                                                           + …
