Information for the installer – Control box
Connecting the control system to a smoke/fire alarm system
Operation
The control system can be connected to a smoke/fire alarm system using the FIRE input at the control
box. In the event of an alarm, all sunshade devices will be immediately retracted and skylights will be
closed. These devices will then be locked in their positions. This makes it impossible for the façades to
be operated locally by using a local button.
The FIRE input connection is made via a floating NC contact from the smoke/fire alarm centre. If the
control box is not connected to a smoke/fire alarm centre, a wire bridge must be positioned at the fire
input between the terminals FIRE and GND.
Cable lengths
The maximum cable length when using cable JY ST (Y) 2 × 2 × 0.8 is 100 m.
Terminals
If not connected to BMS
