This beam sensor can be used for general monitoring, lighting control, and advising signalling (audible warnings, alarm 'chime'
systems, or wired or wireless doorbells etc).
They are not recommended for 'graded' alarm systems, or perimeter or external detection in conjunction with security systems where
'nuisance' alarms are unacceptable.
For intruder alarm / security applications we recommend Takex active infra-red beams due to their increased stability and resistance
to nuisance alarms.

does not cause malfunction but
will affect the product life.
＊Protection distance (between sensor/reflector) should not exceed in the rated range.
The external range may be reduced due to
the possible effect of mist and fog, or frost,
rain, or condensation on the sensor unit
cover and reflector unit, which can cause
nuisance alarms.
＊Sensitivity allowance will be greatly
decreased when the protection distance
deviates from the rated range.
(See the sensitivity allowance-protection
distance curve for PB-11BE)
・Fine tuning using a volt meter is required. (See section 5)
Install the sensor at a height of 80 to 100cm (31"
to 39") to catch a human target.
(Install vertically so that the center of the sensor
lens and middle part of the reflector assembly are
placed at the same height.)
Using the adjustments, the lens can move horizontally
(±90 degrees) and vertically (±10 degrees) allowing
the unit to work in all directions.

＊The sensor and reflector units should be installed uprightly and vertically.
Make sure that the reflector's front side faces the sensor as illustrated.
