The “View Status” screen for the point will now show
Forced ON
.
The Force Device Input screen will now show the
9 - Unforce
option for unforcing the device. (This also
applies if you navigate away from this screen then navigate
back. You could navigate to another point and the forced
condition is still maintained).
Resetting the control panel also unforces any forced points.
Shutdown/Rstart
Use the
Shutdown/Rstart
option to close down
complete loops. All power and signalling is shut down,
allowing maintenance to be carried out on the loop without
having to shut down the complete control panel, for
example.
Also use the option to subsequently re-start the loops.
After navigating to the loop press the appropriate number
key for
1 - Shutdown
or
2 - Restart
.
The status message is displayed as ‘Successful’.
You can navigate away from the Shutdown/Restart screen
and when you return it will be in the same state.
Single Dev.Poll
Single Device Polling is abbreviated as
S.Dev Poll
or
Single Dev.Poll
. Use this option to limit the polling of
devices to one specified device.
This can be useful, for example, in identifying detectors. You
would specify the detector you want to identify, and this
detector will then be the only one that has a flashing LED.
(All other detectors will have an inactive LED.)
After selecting this
Single Dev Poll
option, enter the
address of the device you want to poll. Then press the
Start
key (F4).
To end the polling press the
End
key (F5).
You can navigate away from the Single Device Polling
screen, then back again, before pressing the End key. The
polling continues until you press the End key. You cannot
select another device to poll until you have pressed the End
key.
Change Address
You mainly use the
Change Address
option when
replacing a faulty device, using the procedure below (for
example).
To replace a faulty device
1 Remove the faulty device from its base, replacing it with
a new one.
2 Use this
Change Address
option, to display the type
of screen shown in Fig. 29.
3 For the Old Address, enter the address of the new
device. For newly manufactured devices this will be the
factory set default of “255”.
4 For the
New Address
, enter the address of the
replaced faulty device.
The new device will now have the address of the replaced
device.
3.5.2
Calibrate DDM
This Calibrate DDM option is for use when a loop features a
conventional detector circuit, and the conventional circuit
uses diode bases and the conventional circuit is interfaced
using a FC410DDM.
In such a configuration the removal of a detector can be
sensed, through the resulting change in circuit parameters.
The calibrate option identifies the initial correct circuit
parameters, against which the change can be detected.
CAUTION
When forcing points there is a
possibility of raising a false alarm.
Take the appropriate steps to prepare
for this, such as issuing a warning, or
disabling the signalling equipment.
DANGER
Using Single Device Poll may lead to a
failure or delay in detecting fires
leading to possible death, serious
injury or damage to property.
This is because detectors will be
disabled by using the option. Use with
caution, and only for as short a time as
possible.
