3.3.1 General
The "2-channel lantern module" is a communication slave within the NLS communication system.
It allows the connection of up to two lights which can be switched on or off via relays with two-pole
fuse protection.
The current in the individual light circuits is continuously measured. These values are transferred to
the master which evaluates these values from which it derives status information for the control
panels. Should the current fail to reach the required value, an alarm is generated.
3.3.2 Light circuits
The power supplies (main and backup) are supplied jointly for all two lights via JN1. For switching
between the two power supplies, one switching relay for two lights respectively is arranged
downstream of this supply circuit. The respective voltage is then distributed between the individual
light circuits.
Each light circuit has a current sensor for two current ranges. The first switching operation takes place
for currents up to about 200 mA via a shunt, the second for currents up to about 4 A via a Hall sensor.
Both switching operations are sensed by a microcontroller with 10-bit analogue circuit and made
available for further processing via the FMS bus.
Each light circuit has two-pole fuse protection. Each light circuit can be switched on by the
microcontroller via one relay respectively. For this purpose, the commands from the master arriving
via the FMS bus are evaluated
The light circuits are each combined on the output connector JL1 from where separate wiring to the
respective lights takes place.
Each light circuit can be switched via a toggle switch independent of the microcontroller. This is also
possible in the event of failed or disconnected electronic circuits, thus enabling emergency light
operation.
