14 Modulation End Vent Suction Setting Procedure.
The high/low fire end vent suction adjustment is made using the fan damper. B
Setting Maximum Fire End Vent Suction.
1. Isolate supply from the motorised damper.
2. Press and hold the manual override button (C) — damper can now be adjusted manually.
3. Rotate damper spindle until end vent suction of between 2.5” to 3” WG is achieved. Release the manual override button.
4. Using a phillips screwdriver, reposition the mechanical end stop (A) to final bracket position.
5. Reconnect power to damper. Recheck correct direction of rotation (i.e. when
4mA from controller = damper fully open.)
If this is not correct, use a flat head screwdriver and change the direction switch (B).
Setting Minimum Fire End Vent Suction.
1. Isolate supply from the motorised damper.
2. Press and hold the manual override button (C) — damper can now be ad-
A
C justed manually.
3. Rotate damper spindle until low fire end vent suction of between 0.5” to 1” WG is achieved. Release the manual override button (C).
4. Using a phillips screwdriver, reposition the mechanical end stop (A) to final bracket position.
5. Reconnect power to damper. Recheck correct direction of rotation (i.e. when
4mA from controller = damper fully open.)
If this is not correct, use a flat head screwdriver and change the direction switch (B).

BMS system, by applying a volt free connection (ie closed circuit to enable) across terminals B1 and B0 turns the system on.
Making this connection on a master controller will turn the entire system on whereas making this connection on a slave unit will only bring on that zone.
