INTRODUCTION
The J424 and J408 Control panels
The reduced complexity J424 and J408 Fire Control
panels are the fruit of attentive research and installer
perception. The winning combination of expert wor-
kmanship, high quality materials and essential links
among vital components provide maximum installation
flexibility and performance.
The components of these Control panels operate as in-
tended when the external ambient conditions comply
with the requirements of class 3k5 of IEC 721-3-3:1978.
The J424 and J408 Control panels provides the follo-
wing features: 8 Supervised/Bypassable input zones
(the J408-2 provides 2 and the J408-4provides 4);
2 Supervised/Silenceable/Bypassable fire outputs;
1 Silenceable fire output and 1 Silenceable/Bypassable
fault alarm output.
The J424 model has been especially designed for me-
dium to large residential and commercial applications.
It supports two 8 zone Expander Modules (providing a
total of 24 zones); two Extinguishment Modules and an
LCD Module and provides housing for two 12 V, 17 Ah
batteries. This model is powered by a 2.5 A switching
power supply.
The J408 model has been especially designed for small
residential and commercial applications. It is available
with2(TJ408-2),4(J408-4) or 8 zones (J408-8).
It supports 1 Extinguishment Module and provides hou-
sing for two 12 V, 7 Ah batteries. This model is powered
by a 1.5 A switching power supply.
nAccessory Items
J400-EXP8 Expander Module Kit. This kit comprises
an 8 zone Expander Module and an Expander Control
board. The Expander Module contains most of the
electronic circuitry and electrical terminals whereas the
Expander Control board provides the command keys
and status LEDs of the Expander Module zones.
The Expander Module and Expander Control board are
intended for connection to the Main board of the Control
panel. In the event of an alarm, the Expander Module
will signal the status of its inputs to the Main board
which will activate the fire warning and fire control devi-
ces and generate signalling on the Expander Control
board. The J424 accepts TWO J400-EXP8 Expander
Modules Kits.
J400-EXT Extinguishment Module
False activation of fire extinguishment devices may ca-
use unnecessary inconvenience to end-users and se-
rious damage to property. The J400-EXT Extingui-
shment Module aims at the reducing the false alarm rate
by verifying alarm conditions before activating the extin-
guishment devices.
The J408-8,J408-4 and J408-2 Control panels support
ONE Extinguishment Module Kit, whereas the J424
Control panel supports TWO.
AThe J400-EXT Extinguishment Module IS NOT an
IMQ-SECURITY SYSTEMS listed product.
J400-LCD Display Module
This board has 6 scroll keys and a two-line backlit LCD
(16 characters per line) which provides written informa-
tion regarding the system status.
J400-REP Repeater panel
This Repeater panel is intended for connection (via 4
wires) to J424 and J408-8 Control panels. It provides all
the visual and audible warnings generated by the Con-
trol panel and allows end-users to manage the system
from a remote location (up to 1000 metres from the
Control panel). The J424 and J408-8 Control panels
support up to FOUR Repeater panels.
Software Management Sofware
This user-friendly software application (Windows) of-
fers a quick and easy way to program the Control panel
and provides event logger and print-out functions.
Description
nInputs
This Control panel has special inputs (detection zones)
for fire detection devices, such as conventional fire de-
tectors (i.e. devices which resemble the operating
mode of open contacts during standby status and resi-
stors during Alarm status) and similar devices, such as
Callpoints and gas detectors.
The Control panel considers its inputs to be in standby
status when they pull-down to 0 V with a 3900 ohm resi-
stance. The inputs can detect and signal Automatic
Alarms (generated by fire detectors), Manual Alarms
(generated by Callpoints), shorted lines (generated by
detector faults) and interrupted lines (generated by the
removal of detectors from their bases).
INTRODUCTION 5

AIMQ-SECURITY SYSTEMS certification applies
ONLY when no more than 30 devices are connec-
ted to each zone, and no more than 512 devices IN
ALL are connected to the Control panel.
nOutputs
AThis Control panel accepts devices that operate
within SELV limits ONLY.
This section describes how the Control panel outputs
operate.
Supervised outputs The Control panel will be able to
detect and signal short-circuits and power supply inter-
ruptions on this type of output.
Bypassable outputs The user will be able to disable
(by means of the respective key) this type of output.
Silenceable outputs The user will be able to stop (via
the Silence key) this type of output
The outputs can be silenced for an indefinite period (du-
ring Day Mode) or, for the programmed Silence Time
(during Night Mode).
This Control panel provides the following alarm outputs:
Øtwo Supervised/Silenceable/Bypassable outputs
(NAC1 and NAC2 terminals) with positive polarity

that pull-down to 0 V (negative) in the event of an alarm;
Øone Silenceable/NON-Supervised/NON-Bypassable
output for each input zone (terminals R1,R2, ..., R8)
that will pull-down to 0 V (negative) when the respecti-
ve zone generates an alarm. These outputs allow se-
lective action, as they activate only the devices
connected to the zone concerned.
+The NAC1,NAC2 and DL outputs comply with
EN54-2.
This Control panel also provides:
Øone Silenceable/NON-Supervised/NON-Bypassable
Volt-free changeover contact (TROUBLE terminals)

panel Buzzer and LEDs (Access level 1), and Key and
PIN Code Users to test the zones (Access level 2).
To test a zone: press the respective Zone key (Z1,Z2, ...,
Z24) and the Test key simultaneously.
nExtinguishment Module
This section describes how the J400-EXT Extingui-
shment Module operates.
Activation Mode The Extinguishment devices may be
activated by alarm conditions on ONE of the program-
med zones (OR Mode), at least TWO of the program-
med zones (At least two Mode), or ALL of the program-
med zones (ALL Mode).
Pre-Extinguishment If the programmed ‘Activation
Mode’ conditions occur, the Extinguishment Module will
start the Pre-Extinguishment phase (indicated by glo-
wing on the Pre Ext. LED and by activation of the Modu-
le PR outputs) but will not activate the respective Extin-
guishment devices immediately, thus allowing users to
verify the Alarm.
Extinguishment If the ‘Activation Mode’ conditions
are still present when the programmed Pre-Extingui-
shment time expires, the Extinguishment Module will
activate the Extinguishment phase (indicated by glo-
wing on the Electrovalve LED and by the activation of
the Module’s AE output). The Extinguishment devices,
(connected to the Module’s EV output) will stay On until
the alarm conditions cease, or until the programmed
Extinguishment Time expires (i.e. if the Bistable option
is disabled), or until the Disable Extinguish. key is
pressed.
Auxiliary Supervision Inputs The Extinguishment
Module provides supplementary supervision inputs for
Extinguishment Inhibition, Manual Extinguishment and
Pressure Switch control. These Supervised inputs
must pull down to0V(negative) with a 3.900 ohm resi-
stance during standby status. In the event of interrup-
tion or short-circuit, these inputs will generate a war-
nings on the LED concerned.
nAccess to Signalling and Commands
There are 4 access levels, in compliance with the Fire
Safety Regulations in force.
Access Level 1 Viewing: ALL persons can view the
Control panel status.
Access Level 2 Operating the system (PIN Code ente-
red or Key turned in the Keyswitch): ONLY Key and PIN
Code Users can operate the system.
Access Level 3 Opening the Control panel: ONLY
Qualified persons with authorization are allowed to
open the Control panel door (requires removal of the
screws) for maintenance purposes.
Access Level 4 Repairing or replacing the PCB:
ONLY the Manufacturer should be allowed to repair or
replace the PCB.
nPower Supply

Key DESCRIPTION
Silence This key can be used to restore the Silenceable outputs to standby status (terminals [NAC1], [NAC2],
[DL], [TROUBLE], [ALARM — if duly programmed] and [Rn — if duly programmed]. Silence status
will be held until the Silence key is pressed again or, if the Control panel is operating in Night Mode,
until the Night mode Silence time expires or until a new Alarm/Trouble condition is detected.
Ack./ Evac. This key can be used to refresh the “Pre-Alarm Time” or trigger an Alarm:
For all persons on the premises: If this key is pressed for over 5 seconds during “Pre-Alarm Time”,
the system will generate an alarm.
For Key and PIN Code Users ONLY (Access level 2): If this key is pressed during “Pre-Alarm
Time”, the remaining Pre-Alarm Time will be refresh with the programmed Investigation Time.Ifitis
pressed for over 5 seconds during “Pre-Alarm Time”, the system will generate an alarm.
Reset This key can be used to reset the Fire detectors and restore all outputs to standby status (Supervi-
sed/Silenceable outputs, NON-Supervised/Non-Silenceable outputs and Alarm zone outputs).
Disab. Buzzer This key can be used to disable the buzzer. The buzzer will be re-enable if any kind of event occurs.
Night Mode This key can be used to switch from Day to Night Mode.
Disab./Fault
NAC
This key can be used to disable the Bypassable Fire alarm outputs (terminals [NAC1] and [NAC2]).
Disab./Fault
Telecom
This key can be used to disable the Telephone device output (terminal [DL])
Test This key can be used to test the zones, buzzer and LEDs . If this key is pressed (when the Control pa-
nel is functioning as intended), all the LEDs will Glow and the buzzer will emit a continuous beep.
For Access level 2 Users ONLY: If this key is pressed with the Disable key of a zone (z1,z2, .., z24)
it will activate the respective zone test phase.
z1 … z24 These keys can be used to disable their respective zones. Disabled zones will provide visual signal-
ling of fire and fault conditions but will not activate any outputs or store events in Memory.
Disable
Extinguish.
This key can be used to disable the “Extinguishment” function.
Disable
Manual
Extinguish.
This key can be used to disable the “Manual Extinguishment” function. If this function is disabled, it
will not be possible to activate Extinguishment function via the EM input.
Disable
Automatic
Extinguish.
This button can be used to disable the “Automatic Extinguishment” function. If this function is disa-
bled, the zones will not be unable to activate Extinguishment”.
