Battery faults

For other conventions, see chapter "Security functions", page 153.

FAULT: Battery

The following battery check is performed:
 The battery charging is turned off every 30
 Battery voltage is checked.
 Battery voltage < 24.4 V generates a fault.
Fault message: FAULT: Battery

FAULT: Low battery capacity

The following battery check is performed:
 The battery charging is turned off 60 minutes every 24
 Battery voltage is checked during this 60 minutes period.
 Battery voltage < 24.4 V generates a fault.
Fault message: FAULT: Low battery capacity
If a fault is generated it will be Serviced after the 60 minutes
period.

Watchdog reset

Normally the c.i.e. will be "dead" in case of a watchdog fault, since
the function cannot be 100% guaranteed. The fault relay output will
be "activated" since this relay is powered (activated) in normal state.
In the New Zealand convention the c.i.e. will try to restart. If it was
some small temporary disturbance that caused the watchdog fault, the
c.i.e. might restart and a "restart fault" will be generated as after any
restart – else it will try to restart again and again and again.

Routing equipment isolate (disable)

If any Fire alarm output for routing equipment (Fire brigade tx or
Fault tx) is disabled and you are closing the c.i.e. door, the built-in
buzzer will beep for two seconds. In the display will be shown:
"Routing equipment left disabled". This message has
lower priority than fire alarms but higher than other disablements and
faults.

Acknowledged alarm

When a fire alarm is activated in the c.i.e. it can be acknowledged by
pressing the soft key "Acknowledge alarm" on the c.i.e. front.
