Hard wired panels –
Wall mounted steel enclosure rated IP54 with lockable door.
Inside the panel is mounted a 24v dc unregulated power supply to drive the dampers and LED indicators.
Field wiring is connected via DIF.4 damper interface modules. Each DIF.4 serves 4 dampers and are used in multiples for the required number of dampers.
On the panel facia are mounted LEDs to indicate individual damper status, red for closed , green for open. The LEDs are mounted through an engraved traffolyte label giving damper references.
The simplest panel will operate from one fire alarm zone. All dampers will be held open normally but will close on a fire signal. The dampers will automatically re-open when the fire signal returns to normal.
These panels are generally used with Belimo 24v motor open / spring closed motors. A 4 core cable connects each motor to the panel.
