EATON BiWire Flexi Installation Manual (PR215-216-520-03 15-03-16, PINSTFLEXIINST) March 2016 www.eaton.com 7
2.2 Power Supply Equipment (PSE)
The PSE has been specifically designed to operate the
BiWire Flexi Fire Panel and may not be substituted for any
other power source. The PSE is a Switch Mode Power
Supply located within the Fire Panel cabinet as shown
below. A dedicated 230V AC mains supply is required as the
primary source; the supply is fused on the PCB by a 10 amp
anti-surge fuse. In the event of mains failure the PSE will
automatically switched over to the standby battery power
source until the main power source is restored.
The PSE maintains the charge for the two 12V 5Ah sealed
lead acid batteries in a fully charged state. On initial power up
the batteries will charge over a 24 hour period. Dependent
on the charge of the installed battery the system may initially
shows a charger or battery fault.
The Supply should be clearly labelled ‘FIRE ALARM: DO
NOT SWITCH OFF’ at all isolation points.
PSE faults originating from the following are indicated by
the panel:
• The loss of either power source
• Failure of the charger circuit
• High internal resistance of the battery
The image shows the location of power supply.
(Further technical data for the PSE can be found in section
7.2).
Note that the charging circuit will be in its high impedance
state (approximately 3V DC) if no batteries, faulty batteries,
or only one battery is connected. The full 27V DC (nominal)
charging voltage should be present if the correct batteries
are connected.
In order to test for correct operation of the batteries, remove
the mains 230V AC fuse and allow the batteries to settle
from their charging voltage for approximately 5 minutes. The
battery voltage should then be measured using an electronic
test meter and a voltage greater than 24V DC should be
seen.
BATTERY DISPOSAL INSTRUCTIONS
CAUTION: RISK OF EXPLOSION IF BATTERY IS REPLACED
BY AN INCORRECT TYPE
This product contains batteries and they must be disposed
of in accordance with current waste disposal and pollution
legislation and in particular The Environmental Protection Act
1990, Special Waste Regulation 1996. It is recommended
