Smoke control unit for residential buildings

This smoke control panel manages smoke control on one or two ducts: 

• 32 floors on a conduit
• 16 floors on 2 ducts

At each level, a floor box (BE) manages the various devices and communicates them to the control unit via communication cables (BUS). When smoke is detected or a manual release (DM) is pressed, smoke extraction hatches on the same level are opened to evacuate the smoke produced by the fire.

A manual control box only controls the smoke extraction devices connected to the same floor box. If the control panel is not reset, new zones in alarm will not automatically trigger the other outputs to the smoke extraction devices. However, at any time, it is possible to manually trigger the smoke extraction devices via a control box connected to the control panel. 

All floor boxes, detection and smoke extraction lines are monitored: in the event of a fault, the yellow LED of the zone concerned is activated. The LCD display clearly indicates which detection zones are in alarm or fault, and provides details of the nature of the various system status changes. In the event of failure of one of the floor boxes, the rest of the installation remains operational, and the fault is indicated on the LCD display as soon as the line is restored. 

Commissioning is guided step-by-step by the LCD display, and maintenance and troubleshooting are simplified: a fault diagnosis is displayed on the floor box via LEDs, and on the control unit via the LCD display.
