Use Calibrate DDM under the following circumstances:
On initial commissioning.
When changes have been made, such as changing
detector types, adding detectors or changing the
wiring.
After selecting Calibrate DDM, specify the
Panel, Loop
and
Point
address of the FC410DDM.
Alternatively, leave one or both of these set to
All
, to
calibrate a range of FC410DDM devices as shown in
Fig. 30.
Now press
Enter
.
3.5.3
Restart System
Use this
Restart System
option to restart the panel with
the configured changes.
3.5.4
Switches
Use the
Switches
option to switch various modes off or
on.
For each mode there is a screen for making the switch. On
switching, the screen changes to show the prompt for
switching back again.
You can navigate away from the screens, then back again,
without changing the prompt (so your setting remains in
force until you change it).
Fast Fault Mode
Use
Fast Fault Mode
to reduce the delay between faults
occurring and being reported. You could use this mode to
speed up testing – you might be removing detectors and
checking the panel registers this as a “no response” fault,
for example.
Normally faults must be present for one minute before they
are reported. This is to prevent spurious faults, caused by
electrical noise on the addressable loop for example.
With the display showing
Status: Std Fault
, press the
1
key to switch to
Status: Fast Fault
. Press the
2
key to
switch back.
In “Fast Fault” faults are reported immediately. That is on
the first detector poll that discovers them (or within three
polls for certain devices).
Rate of Rise
With the display showing
Status: ON
, press the
2
key to
switch to
Status: OFF
. Press the
1
key to switch back
again. It is used on certain types of fire detectors to detect
the heat generated and not smoke.
Noisy Device
Detectors showing large variations in values can trigger a
“noisy device” fault indication.
Enable this
Noisy Device
option to suppress these fault
indications.
With the display showing
Status: DISABLED
, press the
2
key to switch to
Status: ENABLED
. Press the
2
key to
switch back again.
Detector Power Up
Use
Detect. Power Up
(abbreviation for Detector Power
Up) to enable or disable the monitoring of detector power
up.
With Detector Power Up enabled, if a detector requires
initialisation (not at power-up),
Detector Power Up
is
CAUTION
Only use Calibrate DDM when the detector
circuit is in its final, operating state. All the
wiring must be in place, and all detectors fitted.
