1.1. General
The MX48 measuring and alarm unit can be fitted with between one and 16 independent channels.
Each channel is connected to one or more detectors installed in the locations to be monitored.
The measurement that is output from the detector is displayed on the MX48 unit and compared with
alarm thresholds. If thresholds are exceeded, the unit actuates relays which can be used to control
external devices.
REMARK
The equipment of the MX48 unit comprises 1 or 2 PCBs (option), each equipped with 4 channels.
However, each channel is independent and can be connected to any type of OLDHAM detector
provided that the PCB is suitably programmed.
