Power Sensing Trigger
The Power Sensing Trigger will turn every installation into an easy control system. Usually a projector needs to have a 12 volt trigger output to send the projection screen a signal to unroll when the system is turned on. Not every projector however has this trigger output, but the Projecta Power Sensing trigger will now give every projection system that functionality.
The Power Sensing trigger will be connected in between the power source and the projector. When the projector is turned on, the trigger senses power going to the projector and signal the projection screen to unroll. When the power is switched of the trigger will signal the projection screen to retract again.
