1: Optimal Sealing by O-Ring
Highly durable Teflon O-Ring was used and special coating
was done at the contacting point of O-Ring to ensure perfect
Sealing and secured operation at fire detecting.

2: Shock proof structure with steel ball support method
With 8 steel ball support structure for shock esistance,
it Is reliably safe from external impact and free from
damage And leakage

3: Low Assembly Load
By minimizing the assembly load with o-Ring Sealing Method,
safety is secured with low pressure inside the Head.

4: Excellent Design
As the head is installed in the building, aesthetic design By
minimizing heat detecting with small head was made.
