WARNING!
If the maximum current consumption of the connected detector is larger than 20 mA, it can
result in malfunctions and damage to the remote indicator.
In order to prevent damage to the device, ensure that the maximum current consumption of
20 mA is not exceeded.
Point-type automatic Bosch detectors already have an internal resistor that limits current
consumption.
