4-wires connection (isolated power)
When using a 4 wires connection, the current loop is provided by the input module or PLC.
The loop (L + and L-) is optically isolated from the detector. 4-20mA or 0-22mA input module
of the PLC has to power up the current loop with, at least 8V at the terminal level.

Relay 1
Only the common and working contacts of the 2 relays are output on the terminal blocks
JP12 and JP13.
To facilitate wiring, the same contacts are output on both JP12 and JP13: the contacts are
connected together, terminal to terminal.
Each relay can be configured :
•
normally closed or normally open. In the last case, the relay are opens when the
detector is no longer powered.
•
on one or more states of the detector (fault, permanent Inhibition, alarms).
Relays configured at factory setting : refer to 6.7.5.1
