Testing and maintenance on the smoke detector
During the operation of the system, dust formation in the the lift shaft
can cause contamination or blockages to the openings on the smoke
detectors. These must be checked during maintenance and removed if
necessary.
Check fault message
Check the transmission path of a fault message to the connected com-
ponents as follows:
1.
Turn the detector insert of a smoke detector in the base counterclock-
wise and remove it.
2.
This leads to a fault in the smoke detector line.
3.
Check fault displays on the
LSF 7000
Control Unit.
4.
Check the display of the HSE push buttons, if necessary check the
forwarding or transmission of the fault to other systems.
5.
Screw the detector insert into the base in a clockwise direction until
it engages.
6.
Smoke detector fault is reset with a delay.
Check ventilation function
Repeat the following steps for each ventilation push button:
1.
Press push button in OPEN and CLOSE direction.
2.
Follow the motion of the smoke exhaustion unit according to the
direction of control.
3.
Check the LED displays in the push button.
4.
Close the system using the ventilation push button.
Check Emergency power batteries
The
LSF 7000
Control Unit is equipped with 2 emergency power
batteries. The batteries are located in the battery compartments of the
control unit housing. They are completely maintenance free and must be
replaced at least every
4 years
. If necessary, check the condition of the
batteries with appropriate measuring equipment. Only batteries appro-
ved by the manufacturer may be used.
Maintenance Timer
The
LSF 7000
Control Unit
offers the possibility of setting a mainten-
ance interval via the configuration software which is subject to licensing.
The expiry of the maintenance date is signalled in the HSE push button
and in the Control Unit (see “Meaning of the displays” and “Help in case
of malfunction or repair”).
If the maintenance interval has expired, it must be reset by a specialist.
The maintenance interval can be reset using the configuration software,
which is subject to a charge.
The following work steps must be repeated for each smoke
detector:
1.
Spray the test aerosol in the smoke detector and activate the alarm.
2.
Check the alarm status display on the smoke detector and Control
Unit.
3.
Check that the smoke exhaustion system opens correctly.
4.
Check alarm via connected siren if necessary.
5.
Reset the alarm by pressing the „CLOSE RESET“ in the HSE push
button or „EMERGENCY CLOSE Reset“ button in the Control Unit.
1.
Activate (let release) the alarm from the FAS / FACU.
2.
Check the display of the alarm signal on the connected FAS / FACU.
3.
Display the alarm status on the
LSF 7000
Control Unit test.
4.
Check that the smoke exhaustion system has opened correctly.
5.
Reset the alarm via the HSE push button.
6.
Check the reset of the alarm on the FAS / FACU.
During commissioning and maintenance (at least once a
year), each smoke detector must be checked for function
by means of a teast aerosol (Art. No. 280.108). Testing
with smoke (e.g. cigarette smoke) is not permitted, as
the detector optics are heabily contaminated.
According to DIN 14675, the detector should be repla-
ced in the process of inspection and must be replaced
after
8 years
at the latest.
An evacuation run of the lift car is activated if necessary!
Do not trigger the alarm from the FAS / FACU yourself!
You are liable for damages!
!
!
!
After switching on, after each interruption of the
power supply for longer than 1 second, or with each
reset signal, the smoke detectors automatically go into
an initialisation phase, which lasts about 4 minutes.
During this time, the red LEDs in the smoke detector flash
briefly every second. The detector then switches to nor-
mal operation.
The installation date must be noted on the batteries!
The maintenance timer is not active when delivered!
Check activation by a connected FAS / FACU
For testing the transmission path for activation by a FAS / FACU, have the
system operator trigger or simulate a fire alarm and proceed as follows:
m
aintenanCe
Press the “EMERGENCY OPEN reset” push button in
the
LSF 7000
Control Unit. The detectors switch to
revision mode for 4 minutes and can be activated with
the test aerosol.
Dispose of removed batteries according to legal
regulations.
