7. Functioning / Adjustment instructions for
the RZ-24-05
7.1 FUNCTIONS OF THE RZ-24-05
RESETTING the complete hold-open system af-
ter an alarm: Firstly reset the fire detectors by
means of the hand release key (1) on the cover of
the casing. For this purpose press the key longer
than 3 s. Now the entire system can be switched
back into operation with the RESET button (2) of
the central.
LED indicator "Trip"
The "Trip" LED indicator lights up red when the RZ-
24-05 detector loop is tripped. The "electromagnet"
output is switched off, the "warning light" output is switched on.
LED indicator "Ready"
The "ready" LED indicator lights up green when the RZ-24-05 detector loop is ready (not trig-
gered). The "electromagnet" output is switched on, the "warning light" output is switched off.
LED indicator "Error"
The "Error" LED indicator lights up or flashes yellow. A permanently yellow LED indicates a seri-
ous defect of the RZ-24-05. A yellow flashing LED indicates various other errors: The individual
errors are indicated by the flashing LED one after the other. The messages are separated by a
pause of 1 second (LED off).
1 x flashing = undervoltage error, i.e. the operating voltage has dropped below 15 V.
2 x flashing = flash memory error of the controller.
3 x flashing = output electromagnet overload or open.
A short flash of the LED "Error" when switching on the controller is normal and serves to test the
display.
Example: Undervoltage error and flash memory error are pending:
1 x yellow flashing, pause 1 s, 2 x yellow flashing, pause 1 s, 1 x yellow flashing, pause 1
s and so on.
