Rotation Sensor (JP17)
Terminal block JP17 at the bottom of the backplane motherboard is for Rotation Sensor
Inputs. See Figure 7. Activate these by a short to common. Only use these inputs with a
rotating electronic siren. When a zone function is run, the speaker array rotates until the
corresponding direction sensor input detects that the array is facing the proper direction.
A rotation time-out timer stops the siren from rotating after 20 seconds, if the sensor is
not connected.
