Warning
Caution
(1) When using multi-level protection, use sensors of the same model for both upper and lower sensors, and set the
same transmission power (H/L) for all of them.
(2) Using these sensors together with sensors from a different series (e.g. PB-HF-KH) may cause interference between
the sensors.
Do not install this device in a location that cannot support its
weight. Doing so may cause the device to fall and cause an
