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.

Installing digital modules
Mounting the CPS 10 sensor module
Mount the sensor modules on a flat surface using two screws (Fig. 1).
The modules should be placed in an accessible area, so that maintenance and inspection
operations can be conducted as easily and as safely as possible. Nothing in the area should
prevent the sensors from obtaining measurements of the ambient environment.
When mounting the sensor module on a vertical surface, position the cable glands on the underside
of the module to ensure proper calibration.
Mounting the other modules
The other modules (relay, logic input, analog output) should be mounted on a DIN rail inside of a
cabinet or an electric box. (Fig. 2).

Central controller electrical connections
Electrical connections are wired through the central controller MOTHERBOARD and the power
supply 24V. For the CPS central controller (wall-mounted version), you must open the casing door
to access the electrical panel.
Electrical connections must be done by a qualified professional. Observe all current Directives,
notably the European Low Voltage Directive. Customers in France must observe standard NF C 15-
100.
Main power supply
Test the current and voltage running through a network before making any connections. Never
connect the device without first disconnecting the power supply. The central controller does not
have an on/off switch.
Protect the central controller from upstream current with a 4A bipolar differential circuit breaker with
a type D response curve. This circuit breaker must be included in the electrical installation of the
building and must be placed near of the device and must be available for the operator. On the circuit
breaker will be indicated that it is the circuit breaker of the device.
Main power supply 100-240VCA: connector terminals L, N, and PE of the power supply 24V (Fig
3) for wall-mounted version or see connector picture 4 for rack version..
Pre-cabled wires are used to connect to the 24 VDC power supply module. The transformer output
connector is also hardwired to link to the 24 VDC central controller connector and to the (optional)
integrated printer for the rack-mounted version.
Grounding the central controller
The central controller is intended for use in areas that meet the Class II requirements for
overvoltage and degree of pollution as per EN IEC 60947-1. In order to comply with the standard,
the internal ground terminal must be grounded (Fig 3).
Digital lines
The various digital modules are connected with “Bus”connectors (Fig. 5). Recommended cable:
RS-485: 2 shielded twisted pairs, 100 .
One pair is used to power the module, and the other is used for communication. The cable shield or
tress should be connected to the terminal:
iData wires and the schield wires should be cut as short as possible.
Internal relay dry contacts
The RCT dry contacts for the 3 internal relays R1, R2, and R3 are available on the CPS central
controller motherboard on connectors J23, J24, and J25 (Fig. 7).
Working load: 2 A at 250 VAC, 24 VCC.
Associated alarm type: R1 (alarm/fault), R2 (alarm), R3 (alarm).
RS-485 serial link out
Recommended cable:
RS-485 cable: 1 shielded twisted pair, 100 . (Fig. 6).
WARNING
Contact with voltage may result in serious
injury or death.

Bicolor (red/green) LEDs located above each line start, on the motherboard, allows for inspection of
the bus links as follows:
LED appearance
Status
Red + Green LEDs lit (LEDs
blink rapidly, almost
imperceptibly)
Orange in appearance
Normal operation.
Red LEDquestion
Green LED response
Red LED blinks once per
second (green LED is off)
Red in appearance
Communication fault.
Missing or faulting module.
Irregular blinking
Poor communication quality
Both LEDs off.
No active modules
Mini-switches
Mini switch A allows the CPS controller to download and
read the user program. When the switch is in the “MEM”
position (open padlock), the user program memory is
accessible and the message “switch open”is displayed on
screen. The CPS central controller waits to download the
program from the COM_CPS software. The CPS central
controller goes into “shut-down”mode when mini switch A is
in the “MEM”position.
When the COM_CPS software programming is complete,
the mini switch should be flipped back to the “Prog”position
(closed padlock), and the central controller should be
rebooted to initialize all of the newly loaded settings.
Mini switch B only used for the central controller’s internal
microprocessor. It should always be in the “Run”position.
Internal relay and buzzer
The CPS central controller is equipped with 3internal relays [R1, R2, R3] and a shared Buzzer.
The operating settings for the relays and the buzzer can be set with the COM_CPS software (see
table below).
The internal buzzer is activated when a specific program-defined event occurs (fault or alarm).
All lines share relays R1, R2, and R3.
The buzzer’s pitch will vary according to the alarm threshold. Alarms 1 and 2 have the same
frequency. Alarms 3 and 4 have a different pitch, allowing the operator to distinguish between alarm
levels.
The buzzer can be disconnected by removing the “buzzer activation strap”(J10) located on the
motherboard next to the buzzer (cf -: Overview of the Motherboard).
