Alarm
Display Unit LLB 10 D |
OPERATION
When a sensor contact closes, the corresponding
indicator LED is lit on the panel.
After the pre-set time, the output contact is
activated. The signal is acknowledged by resetting the sensor contacts,
which there-by causes the output contact to reset.
If the sensor contact returns to normal before
being acknowledged, then the unit returns to its normal status.
LLB-10 can be fitted with a legend for each alarm
channel, or with a common legend for all 5 channels.
INSTALLATION
LLB-10 is designed for panel, cabinet or wall
mounting.
It is made only in the master version.
Systems with more than 10 alarm channels require
additional panels.
Connection is made to the unit by an easily accessible
screw terminal block, which can be fitted with a corresponding terminal
strip.
The use of this system means that cable connections
need not be disturbed once the installation is complete, and that
the unit can be disconnected very quickly.
SECURITY
LLB-10 is designed for severe mechanical and electrical
environmental conditions.
It is provided with protection against polarity
reversal, accidental connection of voltage, interruptions etc.
The unit is designed to indicate voltage failures;
each group relay is designed to indicate voltage failures with each
group relay being normally activated.
In the alarm state the relay is deactivated and
a signal can be given with, for example, a horn. The same thing
happens when the supply voltage is interrupted.
Its limited size and depth allows it to be easily
mounted in panels, walls and similar spaces.
Normal function testing is carried out by pressing
the test button, which simulates faults on the alarm channels in
the system.
The unit is in accordance with CE-standards: EN
50 082-2; IEC 801-2:1991; ENV 50 140; ENV 50 141; IEC 801-4.
