PRODUCT DESCRIPTION: The BBT-2500 is used with the DCR-2500 receiver. The BBT-2500
uses Active Infrared to detect anything that passes through the sensor pair and breaks both
beams at the same time. When the beams are broken, the unit sends a signal to the receiver.
This will sound one of four dierent tones (Classical, Westminster Chime, Ding Dong, or
Whistle). The BBT-2500 can be used to monitor access into any area, from your backyard to
lumber yard and everything in between.

PAIRING
To make installation easier
it is recommended to pair
units ‘A’ and ‘B’ before
mounting.
On a at surface push the
power button (Figure 1-1)
on ‘A’ then push the power
button on ‘B’. Laying the
units at on counter or
table, line up the infrared
light holes (Figure 1-2).
The units will then pair.
You will see lights ashing
during this process. Leave
the units in place for one
minute to make sure this
process is complete.
Once paired, test them by
completely blocking all
3 holes (2 infrared light
holes and indicator hole
shown in Figure 1-3).
Unit should send a signal
to the DCR-2500 and
sound an alert. Unit will
only alert if all 3 holes are
completely blocked for at
least 100ms. If an object
passes through the beam
faster than that it will not
be detected.
