The use of the unit has been projected for the applications specified in the technical characteristics.
Exceeding the indicated values cannot in any case be authorized.
Catalytic sensors are susceptible to poisoning by traces of several substances. This leads to an
inhibition which can be permanent or temporary depending on the contaminant, the concentration
of the contaminant, the duration of exposure to the contaminant.
Poisoning may result from exposure to substances as:
•silicones (e.g. waterproofing, adhesives, release agents, special oils and greases, certain
medical products, commercial cleaning agents)
•tetraethyl lead (e.g. leaded petrol, particularly aviation petrol ‘Avgas’)
•sulfur compounds (sulfur dioxide, hydrogen sulfide)
•halogenated compounds (R134a, HFO, etc.)
•organo-phosphorus compounds (e.g. herbicides, insecticides, and phosphate esters in
fireproof hydraulic fluids
Oldham recommends regular testing of fixed gas detection installations (read Chapter 6).

CPS –User Manual
Chapter 1 Overview of the CPS System
The system consists of:
▪a central controller for collecting readings and managing alarms;
▪various addressable digital modules (sensor modules, relay modules, analog output modules,
logic input modules);
▪instruments and accessories to process alarms and actions
The CPS system can manage the detection of 10 different gases, and all detectors are clearly
localized and identified.
Data from each sensor is collected in the central controller in less than one second. If gas levels
exceed the programmed limits, an audiovisual alarm is triggered and can activate the ventilation
system in the affected area of the parking facility.
Use the COM_CPS software to program the central controller.
The system status can be quickly verified with semi-automatic calibration for various sensors.

The CPS central controller
The central controller is available in a 19”4U (rack-mount) version or in a wall-mount version. It is
designed to control:
▪256 digital modules distributed over 8 lines, with a maximum of 32 modules per line;
▪256 addressable relays max. distributed across all relay modules;
▪224 logic inputs max. distributed across all logic input modules and relay modules.
▪256 analog outputs max. distributed across 4 analog outputs modules.
Modules are connected through a digital RS-485 network using JBUS/MODBUS protocol.
The central controller connects to 256 toxic sensors, and runs on only 24 Watts.
The central controller can be connected to a supervision system via an RS-485 output interface
using ModBus protocol.
Optional features include:
-a battery back-up, ensuring continual operation in case of a power outage (approx. 1 hour for
50 TOX-type sensors);
-an integrated printer (rack-mounted version only) for recording alarms and events;
-an external printer (for both rack- and wall-mounted versions).
Digital addressable modules
Various digital addressable modules can be positioned on the same line.
