4 DESIGN DESCRIPTION
The EKS-4001 monitoring and controlling element (Fig. 1) is a replaceable module in the form of a
printed board with electronic circuits, enclosed by a cover, placed in a case furnished with a terminal
block. Two illuminating diodes are located on the module cover outer side, on the opposite side –
two angle plugs are placed that enable connection of the module with the terminal block in the
CUBO S type case. The following case sizes are available: for one, two and four EKS-4001 modules.
The case bases are drilled in the corners to provide openings for wall mounting. Two PG7 cable gland
seals are located in the case base side wall in order to insert the detection line inputs and outputs.
Additionally, two or four (depending on the case type) PG9 cable gland seals are provided to
introduce the monitoring and controlling wires. A mounting plate with two slots for modules is fixed
to the case base. One slot is designed for connection of the detection line input and output wires; the
other one –for connection of the monitoring and controlling wires. Screens of the detecting line and
monitoring and controlling cables should be connected to the clamps located between the slots. The
case cover plate with a rubber seal is fastened to the case base with four plastic screws. Special
attention should be given to proper alignment of the lug and opening located diagonally.
5 PRINCIPLES OF OPERATION
Communication between the POLON 4000 system control panel and the EKS-4001 monitoring and
controlling element is provided by a two-core addressable detection line. The monitoring and
controlling element is equipped with a short circuit isolator. Actuation of a fire-fighting device (e.g. a
smoke damper) or signalling device (e.g. a buzzer or optical indicator) is achieved due to the element
relay contacts closing evoked by a command from the control panel. The monitoring and controlling

IK-E286-001E 5
element indicates this condition with red flashes of the LED diode. The alarm reset in the control
panel results in the relay contacts return to the initial position. It is possible to disable actuation of
the monitoring and controlling element relays in the control panel in two ways:
•system elements disablement, or
•the EKS element disablement.
Both methods are equivalent.
The monitoring and controlling element actuation depends on the actuation variant set in the control
panel ‘EKS Configuration’ menu.
The monitoring and controlling element enables transmission to the control panel of the following
conditions occurrence:
a) activated relay;
b) technical alarm input 1, input 2 –in case at least one of two EKS element inputs changes its
status to the adverse one (depending on the operation mode), information about this event
is sent to the control panel. The control panel signals this occurrence as a technical alarm;
c) short circuit isolator activation;
d) relay actuation disablement;
e) relay fault;
f) short circuits isolation;
g) EEPROM memory fault –incorrect data saved in the EEPROM memory;
h) output line continuity fault;
i) output 1, output 2 line fault –in case a short circuit or break occurs in at least one line
connecting The EKS input with the monitored or controlled device, the EKS element sends to
the control panel information about a line fault;
j) output 1, output 2 non-maskable fault - in case at least one input is programmed (operation
modes) to monitor the controlled device and this device is activated, and it does not change
its status after the elapse of the TK time defined by the operation mode, the EKS element
sends to the control panel information about a non-maskable fault.
The way how the monitoring and controlling element works is determined by the element operation
mode. During the system automatic configuration, the default mode settled by the manufacturer is
set, i.e. 10000000 in the binary recording (80 in the hexadecimal recording). It means that the EKS
monitors the controlled device line continuity; the relay actuation will take place after 2 s, the second
input operation way is set at NO, the first input operation way is set at NO, the controlled device
actuation is not monitored by the first input and the controlled device actuation is not monitored by
the second input.
The monitoring and controlling element operation mode is set with one bite data in which every bit
means the element actuation and operation way.
Note:
In case any current draw from the controlled device power supply source is impermissible, it is
possible to abandon the line continuity monitoring function. It means that the monitoring circuit
does not draw 535 µA ±80 µA current. For this purpose it is necessary to dismantle the EKS-4001
module, take out the jumper located on the printed board edge near the relay and assembly the
module. An alteration in the EKS-4001 operation mode is necessary –it can be achieved by switching
off the controlled device line continuity monitoring. The operation mode can be set from the menu
in two ways:
-entering the setting in the hexadecimal recording in the Operation mode field;
-selecting the EKS element operation way from the Operation mode submenu.
The monitoring and controlling element is furnished with two inputs that react to non-potential
contacts switching on and off. The control panel indicates this change as a technical alarm. For the
monitoring and controlling element proper operation it necessary to connect resistors in accordance

6 IK-E286-001E
with Fig. 5. Any input lines closing or opening is detected by the monitoring and controlling element
and signalled by the control panel as an input line default. The EKS-4001 monitoring and controlling
element proper connection is shown in Fig. 5.
6 INSTALLATION
The monitoring and controlling elements are recommended to be installed in the controlled devices
vicinity. The monitoring and controlling elements cases should me mounted on walls and ceilings
fastening four screws through the openings in the corners. It is advised to take the modules out
when the case is mounted and use screws with Ø6 expansion anchor bolts.
The installation wires should be introduced through cable gland seals. The detection line conductors
–1 x 2 x 0.8 wire is recommended –should be introduced through two smaller PG7 cable gland seals,
whereas monitoring and controlling conductors - 3 x 2 x 0.8 wire is recommended –should be routed
through bigger PG9 cable gland seals.
It is important that the cable gland seals are properly sealed and unused gland seals are plugged (all
cable gland seals are plugged by default).
For installation wires connection a screw driver use is recommended, its operation part should be
pushed in as far as it goes (see below figure) into the connector smaller hole. Then the wire should
be inserted into the bigger hole and the screw driver should be taken off. It is advised to use a short,
bended WAGO type screw driver (3.5 x 0.5 mm, cat. No. 210-258) that is available for purchase at
POLON-ALFA). The wires connection should be done pursuantly to the descriptions on the connector.
Wires screens should be twisted together and fasten with the screw with washer placed between the
slots on the mounting plate.
7 SERVICING AND MAINTENANCE
The monitoring and controlling element unfailing operation depends on maintaining appropriate
operating conditions, proper installation and periodic inspections performance. The periodic
inspections should be carried out at least once per six months by a person who knows the element
operation to such an extent that allows revealing its malfunctions. The inspection consists in the
element functioning checking in an acting detection installation.

IK-E286-001E 7
Note: The inspections must be executed with special care. It is obligatory to inform proper persons in
the case of any trial actuation of executing devices.
8 PACKING AND TRANSPORTATION
The EKS-4001 monitoring and controlling elements are packed into individual packages and then put
into bulk containers of 10 pcs. The EKS-4001 elements should be kept in closed rooms free of any
caustic gases and vapours at the temperature between +0 °C and +40 °C, and relative humidity not
