1INTRODUCTION
The µ-FEP is designed to be a stand-alone fire detection-extinguishant release panel used in systems
for e.g. electrical cabinets, CNC machines, engine rooms, small area’s or other equipment in which
the user should be able to extinguish a fire rapidly and effective.
This is done by pressing two buttons, external release button or using fire sensor inputs. The μ-FEP
continuously senses its inputs and, in the event of a fire, gives the correct output to enable a product
specific fire extinguishing.
The µ-FEP control panel is designed to meet the requirements of the European standard EN54-2 Fire
Detection and Fire Alarm systems - Control and Indicating Equipment, and the EN12094-1 for Fixed
firefighting systems Part 1: Requirements and test methods for electrical automatic control and the
NEN-EN 15276-2 for aerosol fire extinguishing systems. The µ-FEP is a versatile fire alarm /
extinguishing system with a high-performance level intended for small/compact firefighting systems.
The µ-FEP is a combined fire alarm control panel and extinguishing release system and has two
detection zones, any, or all of which can contribute to the extinguishant release decision. The µ-FEP
extinguishant release panel offers outstanding value and performance for all small, fixed firefighting
installations.

3FEATURES
3.1 ACOUSTIC ALARM
The µ-FEP has an internal attention signal. Malfunctions are standard signalized with a continuous
tone signal, alarms with a pulsating tone signal. Deviating tone signalling takes place with
extinguishing activation and operation of the hold (extinguishing delay) function. The voltage of the
monitored output to drive an additional sounder/beacon is controlled by the µ-FEP and is
independent of the main power supply voltage. In case emergency power status, the sounder output
voltage reduces to 9 VDC what might affect the sound pressure level.
3.2 4HOURS EMERGENCY POWER
To reach the maximum time of emergency power, it is important that the power consumption during
the emergency power status is as low as possible, but that all primary functions will remain active.
Replacing the LIR2477 battery every 3 years will prevent shortening the standby time and prevent
power down in case of increased power consumption during alarm state. When using the MODBUS
communication system, the emergency power capacity is reduced to 3.5 hours.
3.3 COMMUNICATION
The µ-FEP has a Modbus network connection. Modbus enables communication among devices
connected to the same network. A Modbus network consists 1 master and a maximum of 247 slave
units, each with a unique address. For more information, see the MODBUS user manual.
3.4 EXTINGUISHERS TERMINAL BOARD (µ-ETB)
The µ-FEP has as an extra option a special for aerosol extinguishers developed junction box.
See chapter 18 for more details.
3.5 HISTORIC EVENT LOG
The µ-FEP has an historic event log
memory of 10000 events readable from a
USB port. Connect an USB cable between
the Mini-B USB port and your computer.
The device will act as an USB stick.
You operating system will create a new
disk station. The files on the disk station
are text files with logged event. Each time
the µ-FEP reboots, a new file is created
with a new batch number in the filename.
Buttons press events, detailed fault
indication and relay switching events are
logged in the text files.

4ENCLOSURE &INSTALLATION
The µ-FEP control panel
should be mounted on a dry,
flat surface, at eye height to
the signaling and operating
panel, in a horizontal position
so that the enclosure cannot
deformed. The µ-FEP should
be installed in an accessible area. Suitable fixings should be used
at all µ-FEP fixing points such that the panel is securely mounted
and is not liable to move once fixed. Take into consideration environmental
factors such as high temperatures and/or magnetic fields, the µ-FEP control panel can be installed in
another enclosure. A disadvantage can be the inability to witness alarms and / or fault messages on
the spot. The enclosure is provided of 9 predrilled holes meant for cable glands. To ensure IP rating
the cables must be brought in using the provided cable glands.
The FEP housing consists of two parts, so it can easily be
mounted by hand. The rear part with the terminal block in it
and the front part with the panel electronics. The two
parts are connected to each other by a flat cable.
Before installing the panel, it is advisable to start separating
the rear part (backbox) from the front part of the panel.
Open the enclosure by means of a screwdriver (size 3).
Mount the rear part (backbox) at the desired
location. The hinged catch of this enclosures
conceals the installation screws.
Connect the required cables with sufficient length
and connect them to the terminal block according
to the connection requirements.
After the cable glands have been
tightened, the front part with the
electronics must be re-installed and
the flat cable must be re-connected.

5IN-&OUTPUTS
5.1 MONITORED INPUTS
The µ-FEP is equipped with two detection zones and two external button inputs (Extinguishing
Release & Hold). These inputs are continuously scanned for alarm or fault detection. All inputs are
monitored and require a 10 kΩ end of line resistor, even if the input is not used. The button inputs
must have a trigger resistor between 470 and 1000 Ω.
5.1.1 Detection zones
The µ-FEP is equipped with two detection zone inputs. The loop inputs are continuously scanned for
fire or fault detection.
The loops are set to the following values:
▪RESISTANCE of less than 100 Ω: FAULT
▪RESISTANCE of more than 100 Ωand less than 1,5 kΩ: FIRE
▪RESISTANCE of more than 1,5 kΩ and less than 8 kΩ: FAULT
▪RESISTANCE of more than 8 kΩ and less than 12 kΩ: NORMAL
▪RESISTANCE of more than 12 kΩ: FAULT
Note:
When a low resistance (less than 450 Ω) linear heat cable is used, a 470 Ωresistor must be installed
in series at the begin of the loop on one of the wires. Otherwise the wires of the linear heat cable
which will give a fault instead of a fire alarm. Contrary to the linear heat cable, when using Fenwal
thermal heat detector, a resistor of 470 Ωmust be placed in series with the alarm contact, an end of
line resistor 10 kΩ in parallel over the alarm contact and 470 Ωresistor.
The commissioner should ensure to be using detectors with corresponding specifications and the
correct input voltage and alarm resistance of the used detector for the µ-FEP. The maximum number
of detectors in one zone is 4. Devices advised for the µ-FEP are described in the manual.
All monitored inputs are short circuit protected. The voltage of all monitored detection inputs is
controlled by the µ-FEP and are independent of the main power supply voltage. The automatic fire
detectors must have a working voltage between 9 and at least 20 VDC. Each fire zone needs an end
of line resistor of 10 kΩ, even if the fire zone is not used.
5.1.2 External release input
The µ-FEP has a separate input for an external release extinguishing button. The external release
extinguishing button has the same function as the dual release extinguishing buttons (fire buttons)
on the front of the panel. By pressing the external release extinguishing button, the fire
extinguisher(s) will be released. Depending on the dipswitch (time) settings it is possible the release
is delayed. The delayed can be set from 0 to 30 seconds in steps of 5 seconds. These loop inputs are
continuously scanned for alarm or fault conditions.
5.1.3 External hold input
The µ-FEP has a separate input for an external hold-off button. The external hold-off button has the
same function as the internal hold-off button. When an alarm is active and this button is pressed, the
extinguisher release is delayed. When the button is released, the system will wait the configurated
time delay (see DIP switches). Release of the Hold input shall re-start the countdown release timer
from maximum.

User Manual |µ-FEP-EN | November 1, 2020 | version 1.9 10
5.2 MONITORED OUTPUTS
The µ-FEP is equipped with six outputs, two monitored and four potential free. The monitored
outputs are continuously scanned for open and short circuit fault conditions. The potential free
outputs have a contact load of 30 VDC /1A. The monitored outputs are the extinguishing output
(extinguishing release) for a maximum of 5 extinguishing units and the sounder output for a two-tone
alarm signal generator.
5.2.1 Monitored extinguishing output
In combination with the µ-ETB the extinguishing output of the µ-FEP is reverse polarity protected.
Without the use of an µ-ETB, the extinguishing output is NOT reverse polarity protected. In that case
a diode acts as the end of line monitoring device (see specification chapter for more details) with the
anode on the +line and cathode on the –line. A maximum of five aerosol generator ignitors can be
wired in series.
5.2.2 Monitored sounder/beacon output
Sounder circuits are monitored for open and short circuit faults by placing a 10 kΩ end of line
monitoring resistor across the two-tone alarm sounder/beacon. The monitoring resistor must be
connected on the + VDC and first stage –VDC. At a first stage fire alarm, the optical and acoustic
alarm device will be activated. Upon receipt of a second fire alarm (main fire alarm) and/or operation
of the front panel mounted manual release buttons, or external manual release buttons connected
on the monitored manual release input, the optical and acoustic alarm device will be activated with
a different alarm tone. This alarm will also be activated immediately in case of extinguishing delay.
5.3 VOLT FREE CONTACT RELAY OUTPUT
Contact load relays 30 VDC 1A.
▪1 relay output general fire alarm.
The general fire relay will energize upon activation of a fire condition on any of the fire zones
or by pressing of the in or external extinguishing release buttons.
▪1 relay output extinguishing released.
The extinguishing release relay will be energized when an extinguishing activation has taken
place.
▪1 relay output general fault message.
The fault relay is normally energized and will de-energize upon any fault condition including
total loss of power.
▪1 relay output switch off the ventilation/air-co from the protected area.
The ventilation stop relay will be energized upon receipt of a second stage fire alarm and/or
operation of the front panel release buttons or external mounted extinguishing release
button.
