Break glass unit
Break glass unit type WSK 50x are to be used together with FlexiSmoke™. The units are configured and assigned to
smoke zones via the touch screen in the smoke ventilation panel.
Inputs
All inputs and outputs on the FlexiSmoke™ smoke ventilation panel can be freely configured – this means that they can be
assigned to functions across modules and 20A-sections.
Cabling
FlexiSmoke™ 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 break glass units are
series connected, therefore is
not necessary to cable from
each break glass unit to the
smoke ventilation panel
– keypads for ventilation and
smoke detectors are
connected directly to the
break glass units type WSK
501/502 in the smoke zones
System example with
WSC 540
Smoke ventilation panel with
two sections (2 x 20A)
configured in five smoke zones.
Total ±24V standard motor
power consumption in the first
section is 20A (smoke zone 1- 2
- 3) and the total ±24V standard
motor power consumption in se-
cond section is 2A (smoke zone
4 - 5).
The keypads and break glass
units are cabled directly to the
break glass units type WSK
501/502 in the smoke zones
which mean 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 via the WSA 5IO
module.
