    There is no need for the roof toilet exhaust fan to be connected to the direct start line of the elimination control center.

    Because the start of the fan is only related to the distribution box of the fan, the fire control room also controls the power supply of the distribution box of the fan through the signal. The start of the fan is divided into multi-line start (remote direct control) and two-bus start (fire linkage), and the multi-line start requires at least 5 wires, that is, start control, stop control, start feedback, stop feedback, and common ground wire. The fire linkage requires 2 signal buses to control the 24V relay to short the terminals in the distribution box to make the fire fan start.

    The fan you said to the fire control room is not necessary. Because the start of the fan is only related to the distribution box of the fan, the fire control room also controls the power supply of the distribution box of the fan through the signal. The start of the fan is divided into multi-line start (remote direct control) and two-bus start (fire linkage), and the multi-line start requires at least 5 wires, that is, start control, stop control, start feedback, stop feedback, and common ground wire.

    Of course not. It does not fall within the scope of fire protection.

    This is better to set up in the bathroom, which is more convenient and practical.

Theoretically, it's the right thing to do. However, the easiest way is not to use a screen (which may be in the aisle). The easiest way to do this is to keep the door closed and open when you need it.
