User programming via the keypad > Setting and unsetting the system > RESTORE

RESTORE

Alert conditions on the SPC 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). 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. The SPC system does NOT provide the Restore option without detection of the

restored fault.

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.

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.

To restore an alert condition triggered by a zone opening:

Locate the open zone (displays on the keypad).1.

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).3.

The zone that caused the alert displays on the top line.

Press the right menu key to restore the alert.4.

The message ALL ALERTS RESTORED displays.

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.1.

Check that all wires and cables are properly connected.2.

For a tamper alert:

Ensure the lids on all enclosures and devices are correctly closed.1.

If the physical fault cannot be restored to its normal operating state, please contact the installation engineer.

The alarm system still operates by either inhibiting or isolating the fault condition.2.
