Instructions to convert a S4-34440-02 Mains powered
Interface unit
These procedures must be followed to convert a S4-34440-02 Mains
powered interface to a legacy 34440 Mains powered interface unit.
a.
Set the channel rotary switches on the Programmer as per
section headed 'Setting the rotary switches'.
b.
Remove the
Loop
terminal block PB1
j
from the S4-34440-02
Mains powered interface PCB.
c.
Connect the
cable assembly
supplied
,
fitting the 6-way terminal
block end to the
Loop
pins
k
PB1 on the S4-34440-02 Mains
powered interface PCB. Remove the loop terminal block from the
Programmer
l
. Connect the other end of the cable assembly to
the loop pins
m
on the Programmer, as illustrated.
d.
Install and connect the 12V 12Ah batteries
n
inside the
S4-34440-02 Mains powered interface unit enclosure and power
up by pressing the switch SW1
o
. If charged batteries are not
available then power up the S4 mains powered interface using
the Mains supply.
e.
Fit the AC-DC Adaptor lead to the Interface programmer and
connect the mains plug to a mains socket
p
.
Note the programming status LED
q
on the Programmer and
LED
r
on the S4-34440-02 Mains powered interface PCB. The
programming duration is approximately 10 seconds.
f.
Disconnect the
cable assembly
from the
loop pins of the programmed S4-34440-02
Mains powered interface PCB. Disconnect
the battery lead from connector P7 on the
PCB and remove the batteries and leads
from the unit. If mains supply was used to
power up the S4-34440-02 Mains powered
interface unit then power down and
disconnect the Mains cable. Close the door
on the unit.
g.
If programming a number of S4-34440-02
Mains powered interface units then follow
procedures a) to f)
h.
When programming is finished, switch off
the mains supply and unplug the AC-DC
Adaptor from the Programmer.
The S4 Mains powered interface unit is now
programmed and can be used in place of a
legacy 34440 Mains powered interface unit on a
loop circuit of an Analogue Addressable fire
detection and alarm system.
Connect the system cables to the programmed
interface unit and ensure the correct EOL
device(s) are fitted.
