Government regulations specify the installation location and spec. of fire doors, which can separate the building into fire compartments and protect egress paths from smoke invasion. It's essential to ensure that fire doors remain closed so the fire-proof ability of the building is ensured. Government regulations also specify that building owners and users should maintain proper usage of structure and equipment in buildings, and closure status of fire doors must be continually inspected. To provide a durable monitor system to manage closure status of fire doors meets market requirements and can promote enhanced security of buildings. Daily effort for security guards and inspectors to check the closure status of fire doors is required, therefore we want to design and develop a management system to reduce facility maintenance costs.
