OPERATING SEQUENCE (CONTINUED)
To put a range of zones into Auto-Reset mode
From the base display press:
Then press the "ACK" key to put the range of zones nn to mm inclusive into Auto-Reset
mode, or press the "CLEAR ESC" key to abort.
7.4.3 TEST OPERATION
When a zone is put into Auto-Reset mode a reset command is applied to the zone so
that any latched alarm and faults are cleared and an electronic reset is applied to the
circuit.
While in the Auto-Reset mode the zone is automatically isolated from all mapped outputs
except the alarm bell, which operates for 2 seconds when the zone goes into alarm
(unless the bells output is isolated, or the zone is not configured to operate the bells or
the zone is isolated).
On operation of a detector and after the 2 second transient suppression delay the zone
will go into the alarm condition for 17 seconds to allow the detector LED to be checked.
The detector circuit is then reset for 6 seconds to allow smoke or heat to clear.
To assist with identification of the detectors wired to the AZC the current voltage band of
the AZC is continuously displayed on the LCD. B1 (0-3V) is short circuit, B2 (3-13V) is
detector operated, B3 (13-17.5V) is programmable, B4 (17.5-21V) is normal and B5 (21-
22V) is open circuit. The zone status (alarm, resetting, etc) is also shown, with a count
of the number of alarms detected.
Where fitted, the zone alarm indicators latch, flashing when an alarm condition is present
on the circuit and steady on the removal of the alarm condition.
If a fault occurs on a zone in Auto-Reset mode then the Zone Fault LED latches on
steady until the end of Auto-Reset mode, even if the zone is programmed as non-
latching.
Resetting the zone will cancel the Auto-Reset Test mode for the zone.
