PAIRING:
To make installation easier it is recommended to pair units ‘A’ and ‘B’ before mounting.
On a flat surface push the power button (Figure 1-1) on ‘A’ then push the power button on ‘B’. Laying the
units flat on counter or table, line up the infrared light holes (Figure 1-2). The units will then pair.
You will see lights flashing 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. ‘A’ unit contains the radio transmitter module.
The ‘A’ unit transmitter module is factory set to match the zone 2 setting of the DCR-2500. It is not
recommended to change the code setting unless it is needed to avoid interference or a different zone is
desired.
Be careful when opening this unit to avoid damaging any internal components or wires.
‘B’ unit contains no user serviceable parts.
It is not recommended to open this unit.
