Installation and user manual for the
BiWire / Conventional Repeater
Power Supply Equipment (PSE)
The PSE has been specifically designed to operate the panel and
may not be substituted for any other power source . The PSE is a
Switch Mode Power Supply located within the 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
using a dedicated repeater power fault indicator:
•
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 . “PSE
Specification” on page 16 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 .
