Global Fire Equipment JUNIOR MINI-REP Manuale utente
OVERVIEW
The JUNIOR MINI-REP is a fully functional mini version of the JUNO NET Repeater which can be used with any
distributed or self contained JUNO NET or JUNIOR based Fire Alarm system. Its reduced dimensions make it
ideal for installation in reception areas or security booths where it would be impractical and unattractive to
install a full size control panel. Like its big brother, the J-NET-Repeater, the JUNIOR MINI-REP permits full
control of the system from multiple locations. Connection to the JUNO NET or JUNIOR is via an RS422/RS485,
Fibre Optic or TCP/IP interface. The JUNIOR MINI-REP is supplied complete with an RS422/RS485 interface as
standard. Depending on control panel loading, power for the JUNIOR MINI-REP can be supplied from the
control panel’s auxiliary power output or an external 24Volt power supply.

IMPORTANT NOTES
!
competent person.
!A basic knowledge and training in the installation of Fire Detection systems is assumed.
!The Fire Detection system should be designed by a suitably qualified person with reference to the
Local Regulations and Guidance from the fire Officer where applicable.
!All wiring should be carried out with no power present in any part of the fire detection system.
NOTE: This unit should not be used to program the JUNO NET panel as it does not provide total
control over certain programming functions, namely all the functions that involve selecting loops in
the range 2-96 as no switches for loop change are provided.
This document provides detailed information on how to install and operate the JUNIOR MINI-REP when used
in conjuction with any of GFE’s Analogue Addressable Fire Detection panels using GFE’s RS-422/485 data loop
interface (J-NET-INT-RS485-NEW).
Detailed information on how to install these units in a network using either Fiber Optics orTCP/IP interfaces is
available in the appropriate interface installation manual and in the panel’s installation manual.
This unit is compatible with all models of the following panels:
JUNIOR V2, JUNIORV3, JUNIORV4, JUNO NET and JUNO NET EN54
Please note that for JUNIOR V2 and JUNO NET (Classic) panels, certain functions associated with key-switch
presses on the panel’s front display are different than those represented on the JUNIOR MINI-REP. If the JUNIOR
MINI-REP is going to be networked with either of these panel models, a modified overlay can optionally be
provided in these occasions. Please contact GFE for details.
Optionally the JUNIOR MINI-REP can be provided with a key-switch in order to gain access to Aceess Level 2
(Authorised User). Please contact GFE for details.
This equipment must only be installed and maintained by a suitably qualified and technically

INSTALLATION
In order to correctly install a JUNIOR MINI-REP the following steps should be taken:
a) Remove the 4 screws fixing display to the unit’s back box.
b) Disconnect flat cable interconnecting Main Board to Data Loop Interface. SeeFigure3
c) Remove 3 fixing screws that hold the Data Loop Interface to back box. See Figure1
d) Fix unit’s back box in required mounting position using the mounting holes provided. SeeFigure1
e) Re-mount Data Loop Interface on back box using the 3 screws previously removed.
f) Reconnect flat cable connecting Main Board to Data Loop Interface board.
g) Finally connect Power Supply. are supplied by an external 24V DC, normally derived from
the control panel’s auxiliary supply outputs. Do not apply supply voltage until installation is complete.
h) Connect Data Loop Cables to interface following instructions provided in this manual and on appropriate
data loop interface data sheet.
Please also refer to the panel’s installation manual (JUNO NET and JUNIOR) for further details, in particular on
how to integrate the on a networked system. All connections should be performed with all
elements of the fire detection system unpowered.
This unit should be located where access to the internal components is not restricted and where the unit is not
exposed to high levels of moisture, vibration and shock.
Any metal swarf could damage the PCBs if it is still present when the Repeater is powered up so it is
recommended that all PCBs are removed from the box whilst the box is being installed. Make a note of the
positions of the PCBs before removal.
WARNING:
All cables should be screened.
Data loop cable should be RS422/485 grade data cable, eg:
