catch). Beam Power level set to greater than the installation range may also cause cross-talk
with other devices in the line of sight of the transmitter. The Beam Power Control adjusts the
amount of beam energy for optimal range.

High Density
Multiple devices may be stacked on top of each other in high security installations which also
require higher false alarm tolerance against smaller objects. You can use the high density
alarm feature to detect larger objects that only partly interrupt the beams of individual
devices.
This feature allows an alarm condition to be generated when beam pairs are interrupted on
adjacent devices, but not on all four beams within one device.
Connect the first receiver's OUT terminal to the second receiver's IN terminal to form and AND
gate between the two units when stacking units on top of each other. Follow the same
procedure to link up to 8 devices when stacking more than two devices.
–
Only the alarm function is linked between the devices. The EDC and tamper connections
are not affected by this feature.
–
All connected devices must be set to AND gate mode when using the High Density.
–
Use only those connectors which are shipped with the product.
–
The High Density link cable between devices can not exceed 2 m (6.5 ft) length.
–
Always connect an OUT terminal with another device's IN terminal.
–
Do not link OUT terminals of different devices with each other.
–
Do not link IN terminals of different devices with each other.
–
Do not connect IN and OUT terminals in parallel with each other.
