Any user wishing to use detectors other than Oldham detectors must ensure
that they are compatible with the controller, in order the complete installation
to be considered as a safety device.
Transfer table
The following table shows the controller status depending on the detector
analog signal output. In the event the user connects a non-
Oldham brand
detector to the MX 32 controller, the user must ensure that the detector is
compatible with the input characteristics of the controller, so that the
information delivered by the detector will be properly interpreted. In addition,
the controller must provide sufficient supply voltage, taking into account
voltage drops in the cable.
