(1) in downtown area. Nearby lots of traffic congestion, more than a lot of people.

(2) commercial goods within the range, and is flammable.

(3) for commercial security reasons, locking the exit, no voice guidance and fire alarm

Existing commercial security door is difficult to meet the dual requirement of fire and security and commercial aspects are also looking for a facility to solve the contradiction between the two.

In view of the above situation for my company hualian evacuation door installation system, the system is installed in the door (vertical latch). As the evacuation doors are open in the operating area, and are the wooden fire doors leading to the outside, the delay system is used. The delay type fire alarm system is installed in order to quickly evacuate to escape as the pilot, to meet the basic needs of escape, while the alarm voice prompts to achieve the role of security. In this way to ensure the fire escape, cannot be in a normally open state, after the fire alarm siren can cover all the alarm area and commercial personnel can quick evacuation in a relatively short period of time. And when the door is closed, it can stop the fire from spreading. This system completely solves commercial customer any menace from the "rear".
