WIRING TERMINALS
A. 230 VAC supply
B. Input error signal frequency converter (ventilated system)
If not used, lask is retained.
C.
Input for operating signal
External override signal, can be used for night function. All
dampers close if the input is not activated. If not used, lask is
retained.
D. Supply/Bus output to dampermodules
2-wire bus for supply and communication with bus modules.
E. Alarm relay output
F. Smoke fan (ventilated system) relay output
G. Service relay output
Indicates if service is required for smoke detectors
H.
Ventilation relay output
I. External alarm input
Signal from external unit (fire alarm system). 2.2 kohm resistor
must be connected in series. If the input is not used, 2.2 kohm
resistor must be mounted.
J. 0-10 V input for pressure sensor (ventilated system)
24 VDC can be used to supply pressure transmitter. The
pressure transmitter must have a measuring range of 0-300 Pa.
K. Smoke detector input
Up to 10 smoke detectors can be connected in series.
2.2 kohm resistor must be mounted on the last smoke detector.
If the input is not used, 2.2 kohm resistor must be mounted.
L. 0-10 VDC output for frequency converter (ventilated
system)
Analog output for PID control of smoke fan.
M. RS-485/Modbus port
Modbus interface
N.
Fault panel output
O.
Fuses for fault panel
2 x 250 mA , 20 x 5 mm
