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)
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 cross-talk. 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.
