Intelligent Infrared Beam Barriers

The transmitting unit sends invisible Infra Red pulses to a receiver unit at the same time as a synchronizing signal. The receiver will only analyse the Infra Red signal when the synchronizer signal is received. The receiver will not recognize continuous light - neither visible or Infra Red - thus making it practically immune to direct sunlight or deliberate interference. The alarm signal is available as a voltage-free relay contact, normally closed. The unit is fully tampered and a potentiometer adjustment is also available to set the alarm response to crossing speeds between 25 and 300 micro seconds.
