u Quad beams

u Easy alignment (sounder, LEDs, and voltage

readings)

The DS484Q and DS486Q Detectors have separate
transmitters and receivers. The transmitter sends an
invisible infrared beam to the receiver. If the beam is
broken, the receiver signals an alarm. Multiple channel
operation provides increased system flexibility.

Functions

Environmental Discrimination Circuitry

Monitors gradual loss of signal due to dust, fog, rain,
snow, and so on. Normally-closed output opens when
signal loss reaches 90%. Can be field configured to
bypass alarm relay when activated.

Test Features

The transmitters have three features for use in
alignment and testing.

• Voltage output (requires a voltmeter)

• Sounder for alignment

• LEDs (alignment)

u Two coverage ranges

u Four mounting options with optional mounting poles

u Environmental discrimination circuit

Multiple Channel Operation

Configure the detectors for up to eight different
channels. This allows multiple units to be used near
one another without the possibility of receiver cross­talk. This is particularly useful when stacking multiple
beam sets.

And-Or Mode Selection

You can configure the detectors to cause an alarm
when all four beams are blocked, or when either the
upper two beams or lower two beams are blocked.
This configuration detects smaller objects and
eliminates the possibility of someone crawling through
the beam.
