2 Structure of the smoke panel
The WSC 104 contains a power supply unit (SMPS) type WCA 1P1, and a main card type WSA 1SS with input, output and
auxiliary supply (AUX.
The main card type WSA 1SS allows connections of 1 motor line and 1 keypad.
The motor line can be used for either a ±24V standard actuators or MotorLink
®
actuators. The motor line only can have ±24V
standard or MotorLink
®
actuators connected. The smoke panel automatically detects whether ±24V standard or MotorLink
®
actuators have been connected to the panel.
Break glass unit
Break glass unit type WSK 50x are to be used together with WSC 104.
Smoke zone
Only 1 independent smoke zone can be implemented by the panel.
Inputs
Cabling
The WSC 104 CompactSmoke™ uses bus
technology and the overall cabling for break glass
units, smoke detectors and keypads is significantly
reduced compared to other types of smoke panels.
The main card has 1 input for a smoke detector, 1
input for break glass units (where up to 5 break glass
units can be connected) and 1 input for ventilation
keypads (no max number of keypads).
Smoke detectors are either connected to the smoke
detector input or to a break glass unit (type WSK 501
/ 502).
System example
The keypad and smoke detector are cabled directly to
the break glass unit in the smoke zone, which means
that the need for cabling in the building is significantly
reduced.
A wind/rain sensor is connected to close the windows
during comfort ventilation in case of high wind and/or
rain.
The smoke ventilation panel is connected to the Fire
Alarm System.
