Vigilant MX1 Operator Manual Document: LT0344
Page 2-4 8 August 2017 Issue 2.4
In some circumstances, such as enabling a zone in alarm that
currently has no points in alarm or for a zone going into alarm
due to an alarm test, the alarm detail will show the first point
that put the zone into alarm.
In NZ, silencing of the alarm devices is achieved with the Silence Alarms
keyswitch, for use by brigade staff.
This keyswitch requires a Bulgin key to operate. When this keyswitch is
operated:
all alarm devices are silenced,
new alarms will not re-sound the alarm devices,
the COMMON DEFECT and FAULTS indicators will be lit,
the key cannot be removed.
When the Silence Alarms keyswitch is restored to normal, all zones
currently in alarm will be automatically disabled. Refer to the next
section (“Resetting Zones in Alarm”) for instructions for resetting and
enabling these zones.
On a networked system the MX1 may be configured to allow you to
silence alarm devices on remote panels. Refer to Silencing Remote
Alarm Devices in Chapter 9.
Generally the alarm state latches within the MX1 so that each alarm can
be viewed later when fire-fighting personnel arrive at the fire panel.
When the alarms have been investigated and are no longer required they
can be reset.
The condition that caused each alarm must be cleared before the zone
can be reset to the normal state (for example, smoke cleared from smoke
detectors, manual call point element restored to normal).
This function requires Access Level 2.
If necessary, scroll the display with NEXT until the required zone alarm is
shown on the display.
Press RESET
Press OK to confirm the reset command.
While the alarm is being reset, “Resetting” will be shown on the LCD.
If the particular zone in alarm is reset successfully, all alarm entries for
that zone will disappear from the alarms list, the Zone Alarms will reduce
by one, and the Events count will reduce by the number of alarm entries
removed.
