Technical information on Firelock fire-resisting roller shutters

Door leaf

BD120
The armour is made from flat, double-walled galvanised steel sections, material thickness 2 x 1 mm, provided with a mineral wool filling.
All the extremities of the sections are locked to each other to prevent horizontal movement between them. 

B120E
The armour is made from flat, double-walled galvanised steel sections, material thickness 2 x 0.8 mm, provided with a mineral wool filling.
All the extremities of the sections are locked to each other to prevent horizontal movement between them.

Suitable for application in industrial, office, and accommodation buildings, shipping etc.

Motor and controls

Operation of fire-resisting roller shutter

The shutter is driven by a 380 volt three-phase motor with a built-in braking system, designed specially for the fire-resisting roller door The control system is mounted inside a separate plastic casing attached to the motor.
In case of fire, the fire alarm system gives a command to the motor whereafter the fire‑resisting roller door is lowered at a controlled descent speed. In the case of a fire alarm or power failure, the electromagnetic brake is released, whereafter the fire-resisting roller door is lowered at a controlled descent speed.
The motor is provided as standard with emergency manual control by means of a flywheel. Using this control the roller shutter cannot be used as an emergency exit. An emergency supply battery is optional. 

Smart Control box
All roller shutters and roller gates (except 220 V tubular motors combined with single switch) are provided as standard with the comprehensive Smart Control box. A control box with traffic regulation is optional.

The Smart Control box is provided with four signal lamps to indicate the following:

• indication of a maintenance check based on time and number of movements;
• power supply present;
• faults
  (To allow our fitters to read out faults a memory function is provided).
• check that the motor rotates the correct way.

• running time protection;
• continuous motor current; on overload, the motor is switched off;
• a delay time of one second to protect the motor when changing direction up-down and vice versa.
