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 EN60721-3-3:1995.
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
with 2 (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.

Accessory 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 systems may
cause unnecessary inconvenience to end-users and
serious damage to property. The J400-EXT Extingui
-
shment Module aims at the reducing the false alarm rate
by verifying alarm conditions before activating any Fire
Extinguishment systems.
The J408-8, J408-4 and J408-2 Control panels support
ONE Extinguishment Module Kit, whereas the J424
Control panel supports TWO.
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.
J400 Console 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
n
Inputs
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).
+
EN 54-2 certification applies ONLY when no more
than 30 devices are connected to each zone, and no
more than 512 devices IN ALL are connected to the
Control panel.
