The PEM7D is a compact entry and approach warning system for use in shops, reception areas, private homes, etc.
The device consists of a transmitting and receiving unit that transmits an invisible, modulated beam of IR light across
e.g. a doorway, onto a prismatic reflector mounted across from the transmitter. This reflects the beam back to the
receiver to complete the protection circuit. The beam is interrupted when a person walks through it, causing the alarm to
trigger and sound an audible warning. The beam is produced by a LED, which has a much greater lifespan and is less
susceptible to surge and vibration damage than a tungsten filament lamp. The receiver is only sensitive to the frequency
of the modulated light in the beam.
