Other detectors with standardized current output
Any detector (with 2 wires or 3 wires) that can be supplied with power between 19 V DC and 32 V
DC and that supplies a standardized current (signal) of between 4 and 20 mA can be connected to
the MX52 unit.
The connection requirements are identical to those for the corresponding INDUSTRIAL
SCIENTIFIC detectors (see Fig. 22).

Parking application
CTX300 "Co parking" toxic gas detectors can be fitted in parallel when a mean gas concentration is
to be obtained. The detectors must, imperatively, be located in the same area. In this case, a
maximum of five detectors can be connected (see Fig. 23).
