Step 9. Initial Power-Up; Step 10. Re-Fit The Lid - Cooper Security EXP-PSU Installation Manual

the bottom of the EXP-PSU. Use batteries
whose case material has a minimum rating
of UL94V-2 in order to comply with
EN60950 (this standard applies because of
the energy content of 17Ah batteries).
See Figure 17. See page 3 for example
calculations of battery requirements.
WARNING 17Ah lead acid batteries
weigh 6kg each. Do NOT drop.
Connect the battery leads, red to the
positive, black to the negative terminals of
the battery. Connect the other ends of the
leads to either BATT1 or BATT2 (16 and 17
on Figure 3).
If you are fitting only one battery then
connect it to BATT1 (the lower set of pins)
and disable alerts on BATT2 (see the i-onEX
Range Engineering Guide).
Figure 17 Fitting the Batteries
Note: Connecting the batteries without
mains power will not start the system. (See
"Programming Before Installation" in the i-
on160EX Engineering Guide.)

Step 9. Initial Power-Up

Please see the i-onEX Security System
Engineering Guide for an explanation of bus
addressing.
When you apply power to the unit you may
notice the DIAG LED flashing (see 26 on
Figure 3). The LED gives one, two, three or
four flashes a second. Each of these
sequences has the following meaning.
No. Flashes Meaning
One Communication with control
unit over bus is OK
Two No communication over the
bus in the last 10 seconds.
Page 10
Three No bus address allocated to
EXP-PSU
Four No poll request received
from control unit in the last
minute.
The other status LEDs on the pcb (26 in
Figure 3) have the following meaning:
MF Red=No mains AC.
LB Amber = Absent or faulty
battery
12V Red=12V fault
When glowing the following LEDs indicate
possible short circuits in the cabling.
Comms fuse Red=communication outputs
fail (3 in failed. See Note 1
Figure 3)
Aux 1 fuse Red=Aux 1 fuse blown. See
fail (8 in Note 2
Figure 3)
Aux 2 fuse Red=Aux 2 fuse blown. See
fail (13 in Note 2
Figure 3)
Bus OUT Red=The output power on
fuse fail (24 the bus has failed. See Note
in Figure 3) 1
Notes:
1. These outputs are protected by
polyswitches, which will reset themselves
when the short is removed.
2. These outputs are protected by F-1A
20mm fuses which must be replaced once
the short is removed.

Step 10. Re-fit The Lid

Assemble and close the EXP-PSU:
a) Fit the lid of the EXP-PSU into the
back of the case (see Fig 18).
b) Fit and tighten the lid fixing screw.
