1.INTRODUCTION
Prosense PPS Control Panel is produced specially for carparking area. Prosense PPS control Panel is
able to provide automatic gas concentration reading for gases CO, NO and LPG that mostly exist on
car parking areas. PPS Control Panel permanently transmits the gas concentration measurement
from detectors to the control unit. Before the gas concentration in the atmosphere reaches the LEL
or toxic PPM level, the control panel is able to shut off a gas valve, cut off power and turn on an
alarm via activating relays.
Prosense PPS Control Panel can have up to 4 zone modules that each can monitor up to 32 detectors.
A fully configured PPS Panel can handle managing 128 detectors. PPS Panel can be configured
depending on detectors used in each project with one, two, three or four zone modules.
Prosense PPS Panel has three relays on each zone module those are two level fan relays (F1 and F2)
and one alarm relay. Fan relays are not alarm relays. They will be activated after 60 seconds once the
defined threshold level exceeded and deacticvated after 240 seconds than the alarm status returned
to normal. The PPS Panel has one power module that can provide power to all zone modules. This
power module has also two relays which are fault and alarm. These relays will be activated if any one
of the zone modules generates fault and or alarm status.
Prosense PPS Control panel can manage up to 128 addressable detectors via RS485 serial
communication protocol. PPS Panel has an 2x8 LCD display to adjust measurement and alarm levels.
This LCD screen and menu keys allow user to set correct properties for each detector like gas
concentrations by gas type, measument type, range and alarm levels.

2. INSTALLATION
The PPS Control Panel box should never be placed in an explosive atmosphere and should be readily
accessible. It is necessary to drill holes for cable glands either on the top or bottom of the control
unit, depending on which side the electric cables are running in. Before drilling any holes you can
unscrew and remove the electronic parts to avoid accidentally damaging it. PPS Control panel should
not be placed near by high voltage cables or power cable, coaxial cables or transmitters, welding
stations or frequency regulators.
The PPS Control Panel box produced based on IP66 standard specifications. Always use the screw
holes to mount it and do not pierce panel from any other side. Always use cable glands to make cable
entries.
The PPS Control Panel has 4 plastic screws on the front of panel. Use a flat screwdriver to loose them
and remove the cover part on the front. Please take care and remove the connectors on the
electronic card while removing the cover. Fix the panel on the wall via using 4 screw holes after
removing the front cover. Reattached the front cover and tighten 4 plastic screws when wall
mounting completed.

To prepare cable entries, remove plastic covers from top or bottom of the panel. Then drill the holes
for cable entry and install cable glands to the holes you made it. Make sure you are using an
adequate IP66 rate cable gland to assure the box ingress protection is not compromised. The panel
box is modular and can be used with different assemblies. Prosense recommends having cable
entries from the lower side. Electronic board is located in the front cover of the panel. The power
supply is located at the back of panel box. The power must be connected to this power supply. If the
installation requires the connection to a backup battery, place the battery to lover right side of the
panel inside.

4.4 Detector Connections
Each PPS panel zone module can manage up to 32 PPS series detectors via RS485 serial conneciton.
V+, V-(GND), A and B ports must be connected via using four-wire cable. Detector connections supply
12-24VDC power to detector and read the output signal of detector from A and B ports. Thus
connections should be made correctly with extra care to do not mix ports and not cause any damage
on the detectors. Detector power connection should be done with 1.5mm2cross section cable. The
total distance between control panel and detectors should not exceed 800m. Detector connections
should be made with 4 core cable wire that 2 for power and 2 for RS485 and pin definitions are as
follows:
V+

Table 6 : Connection pin definitions
The wiring for detectors utilized with RS485 board should be done by using connection cable EIA
RS485 2 core wires with section 0.22 / 0.35 mm2 and shielded. Nominal capacity between the wires
< 50pF/m and nominal impedance 120 Ohms.
The V+, V- ports and A,B ports are located on same socket in PPS panel zone module. These ports are
formed together on Prosense PPS series detectors on detector main board. The connections should
be done with care to do not mix power and RS485 ports. All detectors will be connected through one
cable via hopping one detector to another till the last detector on the line.

12
PRS-UM-PPSM-EN-Rev.03-10.04.2020
The connection schema given in Diagram 11:
Diagram 11: Panel to detector connections
There should be one master device and up to 32 slave devices in RS485 communication. The master
is DP32 control panel and detectors will be the slave devices:
Diagram 12: RS485 communication
Each detector connected to same PPS panel should have unique address. Detectors having same
address would not be recognised by control panel. PPS panel can communicate up to 32 detectors. In
case less then 32 detectors connected, control panel would not show non-existent detectors. Unused
detectors should be deactivated on channel settings menu steps.
The last detector at the RS485 serial line should have the end of line resistor to enable the total
communication line. Otherwise control panel may not communicate to all, some or none of the
detectors. The end of line resistor controlled by end of line pins located on Prosense PPS series
detectors and can be enabled via putting the jumper on end of line pins. Details are given in section
4.5.

4.5 PPS Series Detectors Connections
Prosense PPS series detectors has onboard RS485 Modbus serial communication module. The
board has 4 ports thus the detector connection should be made by 4 wire that 2 for power and 2
for RS485. The total lenght of the connection line should not exceed 1000 meters.
Diagram 13: PPS series detector board
The wiring for detectors utilized with RS485 board should be done by using connection cable EIA
RS485 2 core wires with section 0.22 / 0.35 mm2 and shielded. Nominal capacity between the wires
< 50pF/m and nominal impedance 120 Ohms.
Detectors will be wired in daisy chain (bus) mode. We recommend not to use star mode connection
due to negative impact of interference. Each detector should have uniqe address number in the
chain. The detectors would not be recognised by control panel if same address given to them. The
address of detector can be adjusted via using DIP-Switch set on the board:

4.5 Relay Outputs
PPS panel has two relays which are fault and alarm on main power module.
Fault: This relay will be activated when any of the zone modules in the system raise fault status.
Alarm: This relay will be activated when any of the zone modules in the system will exceed the
programmed alarm level.
Each zone module has three relays which are Alarm, Fan1 and Fan2. Their activation mechanism as
follows:
Alarm: This relay will be activated when the defined gaz level threshold exceed depending of the
activity type defined for related zone.
Fan 1: This relay will be activated after 30 seconds when any of the detectors will exceed the
programmed F1 level in related zone. This relay will be deactivated after 240 seconds when the
status returned to normal.
Fan 2: This relay will be activated after 30 seconds when any of the detectors will exceed the
programmed F2 level in related zone. This relay will be deactivated afte 240 seconds when the status
returned to normal.
The relays are configured as NO (Normally Open) by default at factory. The relay configurations
cannot be adjusted to NC (Normally Closed)
Important: Relays should not be connected to high current or 220V AC loads. The relay outputs
should be used as control signal and external relays should be used to drive such devices as relay on
main board cannot handle high load.
5. FIRST RUN
After power applied to PPS panel it will start illuminating the On LED. The LCD display shpw
