The FPM Plus fire alarm control panel is a modular device
for monitoring the operating status and control of all the
pieces of equipment triggered as a result or during a fire.
These can be dedicated firefighting systems, such as:
Fire emergency ventilation system,
Fire shutdown systems,
Evacuation support system,
Other building systems triggered to do any action as a result
of fire.
Other systems include:
Access control system,
Burglary and robbery alarm system,
Escalator,
Lifts,
Utilities control (shut-off) systems,
Heat pumps and HVAC systems.
The unit features integration of various types of systems
(with different functions) and building a single control
algorithm (control matrix).

inerting systems, voice alarm system and fire alarm system
equipment, including alerting/alarm devices, fire alarm
receiving equipment, damage alert receiving system,
evacuation lighting systems, internal standpipes and
standpipe valves, external standpipes, pumps in fire water
pumping stations, fire dampers, smoke extraction
equipment, explosion prevention and containment
equipment, smoke curtains and doors, fire doors and other
fire rated closures if fitted with control systems, fire
emergency power shutdown devices, and hoists for rescue
teams;
The control unit is responsible for technical handling of fire
controls in the building. In response to an alarm from the Fire
Alarm System, the unit will control all the firefighting
equipment according to the assumed fire scenario.
As a minimum, the link between the Fire Alarm System and
the Control Unit can consist of:
Zone alarms (‘Fire in a zone’) - number of signals equals the
number of zones - signal from FAS to the FPM+control unit,
Feedback alarms - these should be matched to the needs of
the building. Feedback alarms may include notifications of
the control unit operation in fire mode (trigger confirmation),
notifications of damage to the FAS, indications of alarms and
hazards discovered by the control unit (if needed)

2. FPM+ ARCHITECTURE AND TOPOLOGY
Page 5 of 78
The FPM+ unit has a modular design and is composed of
modules of various types with various functions. Specific
modules may be enclosed in separate single-module
housings or in group housings where more than one module
can be placed in each.
All the modules are connected with a bus loop. Every module
on the bus is addressable. Information is exchanged digitally
between the modules.
The MASTER module is unique among all the unit modules.
This is the main module of the unit, with the function of
overseeing the exchange of information between the other
modules and the exchange of information between the
control unit and the higher level system (BMS, firefighting
equipment integration system). The MASTER module with
additional control unit handling items (buttons and indicator
lights) is always housed in a separate housing (main
housing of the control unit). Together with the MASTER, this
housing can accommodate the power supply and a
maximum of two EPSCUS controllers.
Other modules can be housed in ABS housings or steel
housings.

3. REQUIREMENTS FOR EXTERNAL COMPONENTS
3.1. FPM+ POWER SUPPLY
Page 7 of 78
The FPM+ modules, according to type, can be powered from:
The control unit internal power supply,
External power supply,
Mains power ~230V.
Mains power can only be used when the unit performs
control and monitoring functions over systems which are
not required to work during a fire. An example system of this
type can be a fire damper control system. In this case, mains
3.2. ELECTRICAL INSTALLATION
Electrical installation should be built with flame retardant or
non-flammable cables. The choice of cable depends on the
use of the FPM+ unit in the building. If the FPM+ controls
any equipment or systems which are required to operate
during a fire, a non-flammable cable must be used. If the
FPM+ controls any equipment or systems which are not
required to operate during a fire, a flame retardant cable can
be used.
The general rule is that if at least one system or one
appliance connected to the FPM+ must be operating during
a fire, FPM+ action at the time of fire must be assured.
Therefore, the bus and controller power supply installations
must be wired in non-flammable cables. Connections to
appliances and systems should be wired with a cable
adequate for the requirements prevailing in the building.
For fire safety applications, Certificates of Approval should
be issued for the cables by CNBOP-PIB Scientific and
Research Center for Fire Protection National Research
Institute.
voltage or secure voltage from external power supply units
can be used.
If the FPM+ is expected to monitor and control equipment
and systems which are required to operate during a fire, all
the FPM+ modules should be powered with a buffered
power supply, certified for conformity with EN-PN 54-4 or
EN-PN12101-10, with the supply voltage and output current
appropriate for the specific application.
Cable ways for fire safety applications should be produced
to appropriate rating, i.e. E30/E60/E90, etc. For a specific
application. Conformity with the classification requirements
should be verified by an appropriate certificate.
Example cables:
YnTKSYekw 1x2x0.8 – fire retardant cable for wiring
installations not required to operate during a fire. Can be
used for example to wire a bus linking the modules, or to wire
an MP-Bus.
HTKSHekw PH90 1x2x1 – fire resistant cable for wiring
installations required to operate during a fire. Can be used for
example to connect bus lines.
HDGs 2x1 – fire resistant cable for power supply and control
of systems which need to be powered with electricity during
a fire.
The designer should always make sure that the cable they
intend to use has the requisite approvals and certificates
required by law.
4. FPM+ LIMITATIONS
Page 8 of 78
4.1. NO. OF ITEMS PER BUS
In terms of technical feasibility, a maximum of 254
controllers can be covered within a single bus. These
modules are divided into two groups:
126 x LSK / e.LSK controllers
126 x EPSCUS/e.USP controllers
LSK/e.LSK modules have an address pool attributed on
bus 1..126, while the pool attributed to EPSCUS/e.UPS
modules is 129…254.
LSK controllers can be addressed on the basis of settings
of controls on the front panel of the respective module, or
on the basis of controller serial numbers.
EPSCUS, e.USP and e.LSK controllers are addressed on the
basis of controller serial numbers.
4.2. LENGTH OF BUS BETWEEN
MODULES
The bus is divided into sections. Each module on the bus
is the end and the start of the respective sections to which
it is connected. The length of sections between specific
modules should not exceed 1200 meters.
4.3. LENGTH OF MP-BUS
The overall length of a single MP-Bus (connecting 8
actuators with a single LSK module) should not exceed
600 meters.
4.4. NUMBER OF ZONES
Notwithstanding the number of all zones (fire, control,
smoke extraction zones) that can be covered by the FPM+
unit, there is a limitation of the number of zones to which
a specific output can be assigned. This number is limited
to 70 in the software. Should outputs (EPSCUS and e.USP
relay outputs and LSK and e.LSK actuators) need to be
assigned to a higher number of zones, contact the FPM+
unit manufacturer.

The FPM Plus system is composed of multiple units (the
central module and local modules) with different functions.
The central module monitors the service of local controllers
Modules are set up in FPM+ Configurator.
and facilitates communication between them.
6.1. FPM+ CONTROL UNIT - CENTRAL (MASTER) MODULE
The master module of FPM+ control unit has the following
functions:
exchange of information between other modules
monitoring loop continuity
connection of FPM+ unit with a visualization system (BMS,
SMS).
Fitted with Ethernet port, two RS485 ports, an RS232 port,
eight relay outputs, and eight inputs.
The communication ports as well as two 5A@VDC relays are
installed on the main board of the module, while the inputs
and the six additional 1A@30VDC outputs are located on the
extension board.
Module inputs are used to monitor and control the unit
(managing lights, buttons, access key).
The main unit housing consists of: the housing itself, a
control & alert panel, a power supply with batteries (the
power supply and batteries can be waived upon request and
the unit can be powered from an external certified power
supply), installation pieces (cable grommets, DIN bus bars,
cable trays).

6.2. LSK
Page 17 of 78
The LSK module is designed for controlling and monitoring
actuators and other devices fitted with MP-Bus interface.
Such actuators may include:
fire shut-off damper actuators (e.g. BF24-TL-T-ST),
line actuators of air dampers in HVAC systems, and slide
valves (e.g. LH24A-MP, NM24A-MP, SM24A-MP, GM24A-MP)
SA actuators for dampers and louvres (e.g. LU24A-MP)
actuator valves for water installations (e.g. LV24A-MP-TPC,
NVC24A-MP-TPC)
actuators for water installation valves (e.g. LR24A-MP)
VAV regulators (e.g. LMV-D3-MP)
air pressure regulators (e.g. VRP-M)
Apart from devices supporting the MP-BUS standard, the LSK
module can also control and monitor analog equipment
items, e.g. fire damper actuators. In order to support such
devices, the LSK must be connected to SKC-A module.
The LSK module is also fitted with four potential-free signal
inputs. These inputs can operate in supervised, NO or NC
modes. For the purpose of receiving alarm signals from the
FAS, an input should be configured in line supervision mode.
The primary method of installation of an LSK module is to
place it in a separate housing in the building, near the
equipment it supervises.
Two versions of LSK modules are available: fitted for 230VAC
or 24VAC/VDC power supply. The difference between these
modules is the non-existence of a transformer in the power
system. Besides, the modules are identical and have the
same properties.
Fig. 5 LSK module
6.3. E.LSK
Page 18 of 78
The e.LSK is a more recent version of LSK, a module
designed for controlling and monitoring actuators and other
devices fitted with MP-Bus interface.
Fig. 6 e.LSK module
Below are the primary differences between e.LSK and LSK:
e.LSK is fitted with two MP-Bus items (1 bus in LSK), capable
of accommodating up to 16 actuators (8 actuators can be
connected to an LSK module);
no trip inputs in e.LSK (there are 4 trip inputs in an LSK
module);
different installation method: by default, e.LSK should be
installed in a multiple-module housing of the FPM+ unit on a
DIN bus bar, while LSK is installed in a separate housing.
The primary method of installation of an LSK module is to
place it in a multiple-module housing of the FPM+ unit, while
an e.LSK can be installed in a separate housing in the
building, near the equipment it supervises. Such additional
housing for e.LSK is the same as that for SKC-A.
e.LSK modules are powered with 24- 40VDC/VAC voltage.
6.4. EPSCUS
Page 19 of 78
EPSCUS is the primary control and monitoring module of an
FPM+ unit. It can receive potential-free signals from external
equipment and systems, and is fitted with 8 relay outputs for
controlling external hardware.
In addition, an EPSCUS module has 6 OC outputs which can
be used for connecting indicator elements, such as lights.
A module adapted to measurement of analog values from
different types of detectors is referenced as EPSCUS(A).
An EPSCUS module can be placed:
in the main housing, together with the MASTER module max. 2 items;
in one of the steel housing versions (OZ-FPMPLUS-xx or
OBZ-FPMPLUS-xx);
in an ABS housing for a single module.
EPSCUS modules are installed in multiple-module housings
on a DIN bus bar.
The choice of the specific housing and number of modules
in a housing depends on the building design and the need to
build a control system for fire safety equipment.
The EPSCUS model is designed for 12-48VDC.
Fig. 7 EPSCUS module
6.5. E.USP
Page 20 of 78
e.USP is the more recent version of the EPSCUS module. It
can receive potential-free signals from external equipment
and systems, analog signals (0 30V or 0-24mA, shared
Fig. 8 e.USP module
ground wire) and is fitted with 8 relay (toggle) outputs
designed for external device control.
Differences between USP and EPSCUS modules:
no OC outputs in e.USP (there are 6 OC outputs in an
EPSCUS module);
e.USP has 16 inputs (EPSCUS - 8 inputs);
higher current capacity of e.USP outputs (up to 5A);
additional indicator items (LEDs) for easier startup and
servicing;
terminals supporting cables with core diameters up
to 2.5mm2 (28-12AWG);
closed DIN bus bar enclosure.
6.6. SKC
SKC modules are designed for powering and monitoring the
service of type BF24TL-T-ST actuators. These actuators are
used to energize fire shut-off dampers.
EPSCUS modules are installed in FPM+ unit housings on a
DIN bus bar. Installation in an additional ABS housing is also
possible, such as the housing for EPSCUS module. The
choice of the specific housing and number of modules in a
housing depends on the building design and the need to
build a control system for fire safety equipment.
The EPSCUS model is designed for 12-48VDC.
A single module supports the connection of a single damper
with a single actuator. It converts ~230V mains voltage to
the supply voltage for ~24V actuator.
Page 21 of 78
Fig. 9 SKC module
6.7. SKC-A
The function of SKC-A modules is to supervise the service of
analog equipment controlled by 24VDC or 230VAC voltage
input. Such equipment can include fire damper actuators.
The modules are adapted for integration with LSK modules.
The modules are available in 2 versions, depending on
equipment operating voltage:
230V version - for equipment powered from ~230VAC mains
24V version - for equipment powered with 24VDC
The module can be configured for transmission at 230VAC,
24VDC voltage relay output, or as a potential-free output
only.
The module is configured in terms of output signal (230VAC
voltage, 24VDC voltage, potential-free signal) by the
manufacturer. Such setup can also be done by a trained
service operative. In such case, the manufacturer is not
responsible for service personnel errors.

6.8. FPM+ BUS REPEATER MODULE
The function of FPM+ bus repeater module is to provide bus
signal gain. It is used in layouts with very large distances
between modules, and in high-interference environments
(primarily at industrial sites).
The FPM+ bus repeater module is manufactured by MOXA
as TCC-120I module, but will be tuned by the control unit
manufacturer to the operating parameters of the FPM+
control unit bus. The control unit manufacturer cannot
warrant proper operation of the bus if a TCC-120I module is
used without appropriate tuning.
The FPM+ bus repeater module is installed inside the
housing of an FPM+ unit module and powered with the
supply voltage dedicated to that module. The FPM+ bus
repeater module will always be installed so that one of the
FPM+ bus repeater module buses extends outside the
housing in which the module is installed and the other bus
connects to an EPSCUS or MASTER module installed locally.
Fig. 11 FPM+ bus repeater module
The FPM+ bus repeater module is not addressable and
invisible for the FPM+ control unit. Any damage to that
module can be diagnosed on the basis of broken bus
continuity. If the control unit generates an alert of loss of bus
continuity:
Check the power supply to FPM+ bus repeater module(s);
Check the connection between the FPM+ bus repeater
module and other FPM+ unit modules;
Check the connections between other FPM+ unit modules.
Damage to the bus is indicated by a joint damage alert
(DAMAGE indicator light on the unit’s control panel), in the
visualization system and in FPM Configurator.
