DESCRIPTION OF FUNCTION WITH INDIVIDUAL SYSTEMS OF
GATES SOMATI SYSTEM
A.
System of electromagnet
In case of fire, the central unit of fire alarm system or local detectors send a signal into
the control panel which releases electromagnet holding the gate in open position. After
the magnet is released the gate is closed gravitationally (using an inclined rail). After
alarm of local detectors and the reactivation of the system, it is necessary to RESET
the control panel (Figure 1: Control Panel) pressing the RESET button. If there is not
installed a backup power, the gate also closes in case of power failure. During normal
operation, the leaf can be opened manually with recessed handles and closed by
pressing START-STOP buttons on the control panel (Picture 1: Control Panel). By
pressing the START-STOP buttons once again, the voltage 24V on magnet is restored
and gate stays in open position (due to the magnet). When opening the fire closure,
please, take extra care to avoid mechanical damage of the magnet and its function –
especially, when the gate is almost closed to the end position (max. opening), it is
necessary to reduce the speed of closing (to minimize the impact on the
electromagnet).
B.
System of electromagnetic brake:
In case of fire, the central unit of fire alarm system or local detectors send a signal
into the control panel which releases electromagnetic brake holding the gate in open
position. After the el. brake is released the gate is closed using counterweight system.
After alarm of local detectors and the reactivation of the system, it is necessary to RESET
the control panel (Figure 1: Control Panel) pressing the RESET button. If there is not
installed a backup power, the gate also closes in case of power failure. During normal
operation, the leaf can be opened manually with recessed handles and closed by
pressing START-STOP buttons on the control panel (Picture 1: Control Panel). By
pressing the START-STOP buttons once again, the gate stops. The advantage of the
system is that it enables to stop the gate in any position and also to regulate the
closing speed directly on electromagnetic brake.
