Emergency hatches and doors:
It is of life importance that an emergency door opens after a break down of the electrical system. For those reasons a control box can be provided with a built-in emergency power pack.
If the emergency situation is very critical it advisable to apply doors that can be manually operated after a total break down of electrical network system and the emergency power pack.
Electrical installation:
Roof Hatches and Floor Doors will be supplied with drives installed together with required options as control box, switches, detectors, installation drawings and electrical diagrams. Electrical installation should be carried out by an electrical contractor.
