OPERATION

A sensors flashes when the pre-set time delay has elapsed. At the same time, the output group to which it is connected is activated. The signal is acknowledged by pressing the red RESET button. This releases the output contact and the flashing light becomes steady.

When the fault has been corrected and the sensor contact has returned to its normal state, the indicator lamp goes out. If the fault self-corrects and the sensor contact returns before acknowledgement, then the fault remains in the units memory, the light flashes and the output contact remains activated, until the accept button is pressed.

LLC-10 is equipped with a channel memory. The unit is always ready to receive new alarm signals, independent of system status. The panel can be provided with legends for each alarm channel or with a common 10 point legend.

SECURITY

LLC-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 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.

INSTALLATION

LLC-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.
