Technical data, Smoke central unit Type WSC 308 01
Connection possibilities:
1)
Motors up to 8A.
2)
Smoke detectors, differential heat detectors and/or maximum heat detectors, multi-sensor smoke
detectors (smoke/heat combination detectors), up to 15 units.
3)
Break glass units (primary), up to 6 units (max. current load of the alarm display = 250mA).
4)
Break glass units (secondary), up to 15.
Ventilation buttons with ‚open' indicator, up to 15, any number without ‚open' indicator (max.
5)
current load = 120mA).
6)
Wind/rain detectors with potential free N/O contact (max. current load of the detector = 250mA).
7)
ASC CLOSE function at the smoke detector input (insert ASV module).
Operating/control elements:
The reset button on the control PCB is used to reset a tripped smoke ventilation system and to close the
actuators.
Setting possibilities via slide switch SW1:
SW 1/1 = ON
Maintenance control is activated.
SW 1/1 = OFF
Maintenance control is not activated. Only a coded deactivation is possible following an
activation!
As a control of the activation, the operating LED flashes for 10 sec. If SW1/1 is switched back to OFF again
within this time, the activation process is deleted.
The maintenance control is triggered after the elapse of a 12 month time period. The yellow malfunction LED in
the break glass unit (primary) is lit, and a permanent acoustic alarm signal sounds. Also the green operating
LED is still lit to indicate the absence of a fault. A malfunction message has priority.
SW 1/2 = ON
The transmission of the alarm message (alarm malfunction module 1) is interrupted after 3
minutes.
SW 1/2 = OFF The alarm message (alarm malfunction module 1) is transmitted for as long as an alarm is
tripped.
Setting possibilities via slide switch SW2:
SW 2/1 = ON
The smoke control system trips following a malfunction message from the motor, smoke
detector, SHE switch circuit, over-temperature
SW 2/1 = OFF
The smoke control system does not trip following a malfunction message. The malfunction
message is only displayed by LED`s.
SW 2/2 = ON
The actuators only move OPEN for as long as the ventilation button is pressed (dead man
control).
SW 2/2 = OFF
The actuators move OPEN as soon as the ventilation button is pressed (self-hold).
