pushbutton, delete the alarm either using the RESET button on the casing of the
control unit or by using the ALARM RESET button in the RPO-1 unit (hold the button
down for at least 1 s). The red ALARM diode will be turned off, and the yellow
READY diode will light up.
After alarm release from a smoke sensor
(the sensor line), delete the alarm using
the RESET button. The sensor will not activate the alarm again if there’s no longer
excessive smoke/high temperature. The red ALARM diode will be turned off, and the
yellow READY diode will light up.
After alarm release from an external source
(in/out) one first needs to delete the
alarm in the device which initiated the response of the mcr 9705 control unit.
Depending on the SW1-1 setting, there are 2 possible ways to delete the alarm:
SW1-8 in ON position - After deleting the alarm in the device
which initiated the
response of control unit
, delete the alarm with the RESET key. The ALARM diode
goes out, the READY diode lights up.
SW1-8 in the OFF position - After deleting the alarm in the device
which initiated the
response of the control unit
it will be cleared automatically (in door automation mode
with a delay of 75 s). The ALARM diode goes out, the READY diode lights up. The
actuators of the devices will be actuated by the control unit in the closing direction.
Then delete the alarm using the RESET button. The red ALARM diode will be turned
off, and the yellow READY diode will light up.
If the cause of the alarm can’t be removed
(for examp
le, when there’s an alarm
source failure), one needs to access the segment representing the relevant alarm
source in the SW1 switch in the control centre module (Pic. 3 item 27) and adjust it
from the “OFF” to the “ON” position (in accordance to the description on the optical
signal board
– disconnection of the RPO/sensor/in-out line). In next step delete the
alarm using the RESET button. The red ALARM diode will be turned off.
The yellow READY diode will not light up.
In this case CALL THE SERVICE
3.6. Closing the vents after alarm release
To close the vent, the alarm must first be deleted. After the alarm has been
deleted, the vent will close automatically.
The red “VENT OPEN” diode will begin to
blink, indicating the operation of actuators. Once the smoke exhaust vents are
closed, the “VENT OPEN” indicator will be turned off (
after approx.
140s.)
3.7. Diagnosis of the faults
Optical indicators (Pic. 2) placed on the inside part of
the central unit’s door
enable identification of the system’s defects.
A blinking “FAULT” diode provides information about the mains failure or
batteries failure. In this case, one has to check whether there’s voltage (230 V) on
the control unit’s terminals and the status of FS1 and FS2 cut-out fuses (see page
7).
If there is a signal indicating a fault in the actuator line, check the on board fuse
FS3.
