The i-5 Infra Red Beam
is used primarily as a safety device to detect the presence
of a vehicle or person moving through an entrance.
INDICATORS
Both the transmitter and
receiver are fitted with a Green LED indicator. The LED
in the Tx illuminates when the power supply is ON and
in Rx when the beam is aligned.
OPERATION
The i-5 Infra Red Beam
consists of a transmitter and receiver unit mounted on
opposite sides of the entrance. The transmitter sends
a modulated infra red beam to the receiver. When the beam
is interrupted the receiver changes the state of an internal
relay. The contacts of the relay are potential free and
can be wired as normally open or closed.
