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 show 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
Figure 2 shows the location of the power supply. “Individual
Zone Test” on page 25 provides a full technical specification
for the power supply.
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 present.

BATTERY DISPOSAL INSTRUCTIONS
WARNING
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 that
