FireClass J400REP - Installing Expander Module Kit (for J424 ONLY)

4. Using the Jumper (43), marked “1” on the PCB, set
up the Extinguishment Module address:
Jumper (43) IN = Extinguishment Module nr. 1;
Jumper (43) OUT = Extinguishment Module nr. 2.
+
The Jumper (59), marked “2” on the PCB, MUST
BE INSERTED.
5. Using the Flat cables connect the Extinguishment
Modules as follows:
if you are installing ONE Extinguishment Module
— connect it to the Main Board, via the jacks (58
and 63 respectively), as per Fig. 9a;
if you are installing TWO Extinguishment Modules
— connect Extinguishment Module nr. 1 to Extingui
-
shment Module nr. 2, via the jacks (56) then, connect
Extinguishment Module nr. 1 to the Main Board, via the
jacks (58 and 63 respectively), as per Fig. 9b.
6. Place the label provided with the Extinguishment
Module next to the data label that is already present
on one of the Control panel’s sides.
+
The polarity of the Flat cable connectors must be
observed.

Installing Expander Module Kit (for J424 ONLY)
This Expander Module Kit comprises an 8 zone Expan-
der Module and the Expander Control board. The
Expander Module contains most of the electronic circu-
itry and electrical terminals whereas the Expander Con-
trol board provides the LEDs and control keys for
Expander Module zones.
Install Expander Modules as follows:
Ø if you are installing ONE Expander Module Kit,
mount the Expander Module (21) and the Expander
Control board (10), as per Figure 11a;
Ø
if you are installing TWO Expander Module Kits,
mount Expander Module nr. 1 (21) and the Expander
Control board (10) to the backplate then mount
Expander Module nr. 2 (25) and the Expander Con
-
trol board (7), as per Figure 11b.
+
If you are installing ONE Expander Module Kit only,
the location will be different to that shown in the
diagram.
