Alert conditions on the intrusion control system are indicated on the Keypad by a
flashing yellow Alert LED and by activation of the buzzer. The Keypad indicates the
location and nature of the alert condition. The ability of a user to restore alerts
depends on the security grade setting of the system (in accordance with standards
[1]). An alert condition can only be restored once the fault or zone that caused the
alert has been physically reset to its normal operating state; e.g. an open zone has
been closed again or a severed X-BUS connection re-established.
Users may be restricted from using the Restore feature if an Engineer chooses not
to select 'Restore' within the User Rights menu for select users. Users who cannot
restore an alert receive fault messages on the Keypad until the zone or fault
condition is either inhibited or isolated.
Alarm conditions on the SPC system are indicated on the Keypad by a flashing
yellow Alert LED (see Section Fehler! Verweisquelle konnte nicht gefunden
werden., Using the Keypad) and by activation of the buzzer. The Keypad displays
the location and nature of the alert
condition.
To restore an alert condition triggered by a
zone opening:
1.
Locate the open zone (displays on
the Keypad) and restore the alarm
sensor to its normal state by closing
the door or window.
2.
Enter a valid user code and select the
RESTORE option (right soft key). The
zone causing the alert displays on the
top line.
3.
Press the right menu key to restore
the alert. The message ALL ALERTS
RESTORED displays and the
flashing Alert LED turns off.
For system or communications type alert
conditions (Mains failure or X-BUS disconnect), locate the source of the alert
condition and check that all wires and cables are properly connected.
For a tamper alert, ensure the lids on all enclosures and devices are correctly
closed. If the physical fault cannot be restored to its normal operating state, contact
the installation engineer. The alarm system still operates by either inhibiting or
isolating the fault condition.
NOTE
An Alert condition only displays on the Keypad when the system is UNSET. If the system is SET when
an alert condition occurs, the Keypad gives no indication of that alert condition until such time as the
system is UNSET.
