Electrical Operation of Roof Hatches and Floor Doors

Depending on door type, cover weight and other requirements we can install one or more rack-and-pinion drives. These drives are available in 24 Vdc or 230 Vac

This system is controlled with a surface mounted or built-in switch.
Operation of two drives through one switch is possible.
Operation and control 24Vdc
Operation of one or more drives is controlled by a control box with rectifier that is connected to the electricity network.
Features
- communication with central alarm system
- emergency switch
- certified for smoke vent system / fire resisting system
- programmable
- operation control of other objects
- control by automatic detectors - smoke, rain, wind, fire etc.
- automatic sequence control of two covers that are overlapping
- automatic stop in case of unequal load or overload
- etc.
Depending on the features we will recommend a suitable control box type.

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.
