Description<\/h2>
<\/div><\/div>[vc_empty_space][vc_column_text]<\/p>\n
\n

The functioning of the\u00a0Active smoke curtain SC1 and FC240<\/b>\u00a0is carried out by a\u00a0Control Panel<\/b>. Each panel can control up to 6 motors of 24 V.<\/p>\n<\/div>\n

<\/div>\n

Operation<\/h2>
<\/div><\/div>[vc_empty_space][vc_column_text]<\/p>\n
\n
\n
\n
\n

Under normal operating conditions, the panel provides a 24 V supply of alternating current to the curtains motor to keep the curtains gathered up. If smoke was detected, the fire alarm contact in the panel will be opened due to the alarm control system. The panel will eliminate the 24 V supply of the curtain motors and the curtains will go down under gravity, in a controlled way.<\/p>\n<\/div>\n<\/div>\n

Features<\/h2>
<\/div><\/div>[vc_empty_space][vc_column_text]<\/p>\n

As soon as possible, the fire alarm system will restart, the panel will restore the 24 V supply to the motor curtains and the curtains will go up. Circuits limiting the current will detect that the curtain is fully gathered up and the supply tension will lower to a holding voltage. Each panel has a 24 V 7aph, which enables the control of the system in case the power supply breaks down.<\/p>\n

MOTOR FOR ACTIVE SMOKE CURTAINS<\/h2>
<\/div><\/div>[vc_column_text]<\/p>\n

Our motor and the circuit control of the 24 V were redesigned in 2001. We have now a new circuit control which allows each motor to lift a weight of 20 kg and at the same time, it is capable to pass the 2000 cycles test as required in BS 7346: part 3. The new supply capacity has made possible for the curtains to be manufactured with a fall of 12 m over a 2,8 m roller width.<\/p>\n

The control circuit of the motor is housed in a remote space in order to help the maintenance engineers. The control circuit can be reached to carry out the routine maintenance supervisions with no need of removing the\u00a0Smoke Curtains<\/b>.<\/p>\n

Up to six control circuits of the motor can be connected to the control panel. Motors with a 127 mm tube, consume more and can be connected to a maximum of three units to the control panel of the group.<\/p>\n

Dimensions of the motor control circuit: 145 mm height x 250 m length x 50 mm depth. Motors are made of CC with permanent magnet.<\/p>\n

Due to its modest size, these motors are quite suitable for semi industrial applications, such as the curtains rolling up or the automatic doors.<\/p>\n
