Short-circuit monitoring of the connection cables, charging voltage disconnected in the event of a short-circuit.
Malfunction Function
Diagnosis
Yellow battery – LED flashes
Mains failure or charging voltage
below 25V
Check the mains fuse and the
charging voltage
Yellow battery – LED is lit
No battery or battery voltage below
18V
Check battery, battery voltage and
battery fuse

Optional plug-in modules:
Multi-input malfunction warning module (WSA 301) – Model 1:
Multi-input malfunction warning:
1 x change-over contact (max. load: 60V, 1A) with 3 pole connection terminal for potential free transmission
to the BMS / panel etc.
2 pole connection terminal for 2 wire BUS cable for the feedback of malfunctions in cascaded control centres
to the break glass unit connected to the master smoke control unit.
Alarm message:
1 x change-over contact (max. load: 60V, 1A) with 3 pole connection terminal for potential free transmission
to BMS / panel etc., or as monitored 2 wire alarm cable for cascading control centres.
Jumper plugged in J1 = Only for the alarm transmission to the next smoke control panel unit (cascading).
Jumper plugged in J2 = pot.-free alarm contact (factory setting).
Wind/rain relaying module (WSA 302) – Model 2:
1 x change-over contact (max. load: 60V, 1A) with 3 pole connection terminal for potential free transmission
of the wind/rain trip.
Ventilation time module (WSA 303) – Model 3:
Automatic closing in the ventilation mode according to preselected time (1 min. to 30 min.)
after ventilation OPEN was actuated.
Installation information:
Fit the break glass units at a height of approx. 1.40 m of FF top edge.
