General
The LCU-P is designed for the connection of two systems of
AOPD type 4 sensors or up to four systems of AOPD type 2
sensors. (1 pair = 1 emitter and 1 receiver) "Mixed"
operation, i.e.
1. Sensor 1 system type 4 and
2. Sensor 2 systems type 2
can also be considered.
Type 2 sensors are always to be used in pairs, i.e. 2 systems
of type 2 or 4 systems of type 2 are used. The automatic
testing of type 2 sensors increases the protective level of the
whole protective system (no external measures needed).
Instead of a second AOPD type 4 sensor, an extra LCU (type 4)
can also be connected, in order to "daisy chain" LCU's, see
fig. 1.
Muting of only directly connected LCU control
In case of daisy-chaining of LCU the sensors may only be
muted by this LCU where the sensors are physically connected
(do not mute inputs where LCU are connected).
