LED-signalling modules Device description The LAB signaling modules are compact indication units in a panel mounting housing with 8, 16, 24, 32, 40 or 48 signaling inputs. The units have an internal lamp test button and the connection for an additional external button. DIP switches are located under the front panel of the unit to configure the following functions: • Group-wise (groups of 8) switching between normally open and normally closed principle of the inputs • Group-wise (groups of 8) inclusion in the collective alarm • Inverting the collective alarm If the input of a group is...

If the signal inputs are operated in normally closed mode, unused inputs must be connected to + or L.

LED-signalling modules DIP-Switch After taking off the front frame and removing the front panel, DIP switches become visible. In the following figure, a LAB with 48 alarms is shown as a representative of all devices. Depending on the number of channels of the indication module, there are different numbers of DIP switches and they have the functions described in the tables below. Function with switch position „ON“ LAB 08 LAB 16 Alarm 1-8 is included in the collective alarm Alarm 1-8 is included in the collective alarm formation formation Alarm 9-16 is included in collective alarm formation...
