Connecting: Insert the stripped cable end (no braided wire) into the terminal.
Disconnecting: Turn wire alternately to the left and right, thus pulling it out of the terminal.
Up to 4 detectors can be connected to each MPA.
Three inputs (terminals 2-4) allow adjustment to various line technologies.
Connection depending on the line technology

A resistor is necessary to connect to terminal 4; otherwise, the LED
may be damaged.
All current Bosch detectors are equipped with an internal resistor to
restrict current consumption.
Caution!
If the current consumption for the connected detector exceeds 20 mA, it can lead to the mal-
!
function of or damage to the MPA.
You should restrict the maximum detector current consumption to 20 mA to avoid damaging
the MPA.
Notice!
i
The cable length between the detector and the MPA must not exceed 3 m when connected by
an unshielded cable.
