INSTALLATION
This product is designed for the use in automatic fire detection and fire alarm systems. If the PSE is used as a power
supply for Control and Indicating Equipment (CIE), the PSE shall be installed no further than 10cm from the CIE, and
close coupled by conduit. Where this is not possible, see ‘DUAL PATH’ section 41 for EN54-4 compatible equipment.
Mains Feed
1. This unit must be fed from a mains power source via a separate (approved) disconnect device and fitted
with a fuse or other over-current protection device rated at 5A maximum.
Ensure that the disconnect device used has appropriate earth fault protection to the applicable
standard.
2. Where the PSE is used to provide power to a fire alarm circuit, the mains isolation and disconnect device
should be provided solely for this purpose and be suitably marked “FIRE ALARM – DO NOT TURN OFF”.
All cabling should meet national and local fire system installation regulations, e.g. FP200 type cable for
high integrity installations.
3. Where the PSE is used for other applications, it should be installed according to all relevant safety
regulations applicable to that application.
Cable Sizing
4. Mains input cable must be to the applicable standard with a 5A, or greater, current capacity, i.e. 0.75
mm2 nominal conductor area, having a minimum operating voltage of 300/500V ac.
5. The low voltage output cable must be sized to carry the rated load current to the devices connected to
the PSE.
6. Mains input and low voltage output cables should be routed to use different entry / exit holes in the
case. Cable glands should be used to protect cable sheaths from chafing. Ensure that the glands are
correctly sized (i.e. close fitting with respect to cable sizing). Note that the glands should meet a
minimum flammability specification of UL94 HB.
7. All cabling should be securely fastened in position using a cable tie linked to the fixing points provided.
Mounting PSE enclosures
8. Using the appropriate fixing points, fix enclosure to a suitable surface, ensuring that wall fixings are
appropriate to support its fully loaded weight.
9. Knock-outs are provided in the case for mating with external trunking or conduit
10. Ensure that all unused holes (on the rear of the case) are sealed to prevent the ingress of dust and
moisture

CAUTION – DO NOT CONNECT the two remaining (free) battery terminals to each other
27. Using the battery lead provided, connect the two white wires to the “Temp” terminals on the PSU
(polarity is not important) and the RED lead to “Bat+” and
the BLACK lead to “Bat–“.
CAUTION: Connect battery leads to PSU terminals FIRST - THEN
connect to the battery LAST.
28. Connect the red battery lead to the free positive battery
terminal and the black battery lead to the free negative
battery terminal.
CAUTION – significant energy can be released from an SLA
battery. When connecting the last battery lead, take extreme
care to attach the cable ONLY to the correct terminal. Avoid
shorting it to any other terminal or conducting surface.
CAUTION – the supplied battery lead contains a temperature sensor – DO NOT attempt to modify this
lead in any way and do not use an alternative method of connecting the batteries.
29. Reconnect the mains supply and verify that Fault LED #3 is off and Battery LED #2 indicates flashing or
constant Green. 2402ST only accepts batteries >= 22V.
Note: Batteries as low as 19V may be connected, but this is NOT ADVISED as this could indicate damaged
batteries. To connect batteries as low as 19V, carefully disconnect one white temperature sensor wire from
the “TEMP” terminal block). This will induce a thermistor fault. Then wire the batteries to the terminals
(follow steps 27-28). Once the batteries are charging, clear the thermistor fault by reconnecting the
thermistor wire.
30. Verify GEN Fault relay n/c contact is closed, (com to n/c terminals = short circuit)
31. Disconnect the mains power. Verify that the green Mains LED #1 extinguishes, and the Yellow Fault LED
#3 starts to flash (indicating that the PSE is running from its standby batteries).
32. If connected, verify that the EPS Fault output shows an open contact (com and n/c terminals = open
circuit) and the GEN PSU Fault output shows a closed contact (com and n/c terminals = short circuit).
33. Verify that the standby batteries are now supporting the system load. Perform a full functional test of
system including full alarm condition Note: ensure batteries have sufficient charge to support the
system under full load.
34. To prevent battery fault indication when no battery
is required, fit the “No Battery” link ( ).
Please note; fitting of this link invalidates EN54-4,
EN12101-10 and NF S 61-940 compliance.

3 Diagnostic Red flash x2 (repeating) Indication: Fault = missing battery indicated
4 OP1 Constant Green Indication: Output 1 = OK
5 OP2 Constant Green Indication: Output 2 = OK
6 Batt Constant Yellow Indication: Battery Fault = missing battery indicated
(See also ‘Status and Fault-Diagnostic LED Indication’ table for full details of LED indications.)
39. Reconnect the battery lead and, after approximately 3s, verify that that the Fault LED #3 does not flash.
(Audible click can be heard as the battery relay closes, then a second click while the charger is tested.)
Note: If it is necessary to obtain confirmation of charging current; between steps 28 and 29, an ammeter
can be placed in series with the battery leads. Continue to observe caution with all exposed conductors
when inserting or removing the meter and when restoring normal battery wiring
40. Close cover and secure using fastening screws provided.
OPERATING INSTRUCTIONS
In the event of loss of mains, a battery fault or a GEN fault, the corresponding Fault relay (signal) contacts
will open, and the LED indicators will display the fault condition and overall status of PSE.
If the output of the PSE fails, the cause of the failure should be investigated, also by referring to the ’Status
and Fault-Diagnostic LED Indication‘ table, e.g. short circuit on load terminals or connection of a deeply
discharged battery. The fault should be rectified before restoring power to the PSE.
If any of the fuses require replacing, ensure the correct fuse rating and type is used – see page 2
MAINTENANCE
This unit is intended for use by Service Personnel only. There are NO USER SERVICEABLE parts inside.
There is no regular maintenance required of the PSE other than periodic testing, and replacement of the
standby battery. Reference should be made to the battery manufacturer's documentation to determine
typical/expected battery life with a view to periodic replacement of the battery.
