Hazmat Lockdown
Hazmat Lockdown
DSX can accommodate the quick lockdown of a system required for Hazmat
alerts. The Lockdowns occur without the need of programming or lengthy downloads.
Hazmat Lockdowns will typically secure all the doors in an area or the entire
facility not allowing anyone or just particular personnel access in or out.
This application is based on the new Time Zone linking features of the
WinDSX 3.7 and higher software. It requires that all controllers in the
location have a 1040 processor and firmware version 3111 or higher.
Below we will discuss what the Triggers are for Hazmat Lockdown (links)
and what the different components are that we will be linking to and how they
will respond.
Triggers – The activation of Hazmat Lockdowns can be from several sources.
Virtual Outputs can be defined and assigned Linking Groups so that their
manipulation in the Workstation program activates a Linking Group. This allows
the control to be from Output or Override Group Icons in Workstation. An
Operator would click on the appropriate Icon and set it secure for example to
lock all doors. Using the same Icon the system can be put back to its normal
operation. This requires the Comm Server PC to be
online for Hazmat Lockdown control.
A different Trigger could be a card read at a particular reader. This
could be a normal card used at a particular reader or it could be a particular
card used at any reader. This type of Trigger would work without the Comm Server PC online.
A push button (latching switch) can be connected to an Input allowing
the Trigger to be ready and active even when the Comm
Server PC is offline or the software is not running. Placing the switch in one
position initiates or triggers the Lockdown and setting the switch back to
normal resets the doors to their programmed state (Time Zone). If a momentary
switch were used it would require that there be one to initiate the Lockdown
and a different one to put everything back to normal.
Components to
Control - Access Levels,
Devices (readers/keypads), and Outputs all can be assigned and controlled by Time
Zones. This allows Time Zone Linking to also control these components.
By linking to a Time Zone that is part of an Access Level we can force the level to
allow or deny access immediately. By linking the Time Zone OFF, the cards stop
working and by linking it ON we can force the cards to work regardless of the
Time Zone schedule definition.
By linking to a Time Zone that is assigned to a Device we can force that reader/keypad
to work or stop working altogether. If we link the Time Zone ON the Device will
read and process the cards. If we link the Time Zone OFF the Device will shut
down and not read any cards regardless of their Access Level.
By Linking to a Time Zone that is assigned to an Output we can affect the On/Off status
of that point. If the Time Zone is set to
Programming – Here
are the general programming parameters. You will have to substitute the
appropriate Device, Input and Output addresses.
Location – Select “Enable Linking Logic” and select “Code to Linking Logic” if
you will trigger any links with a card read.
Device – Select “Device Used for Code to Linking Logic”. This could be any
and all Devices where a card would be used to trigger the Threat Level Linking
Groups.
Output – Create Virtual Outputs if you want to use Icons in Workstation for
the Trigger. This is an Output that does not physically exist but operates as
if it did. This could be Output numbers 3-8 on any 1042 Device. This
application will require one Virtual Output for each different group of actions
you wanted to control. Do not assign a Time Zone to these Virtual Outputs and
set them for “Perform Link on Secure”.
Inputs – Define the Trigger Inputs. These would be the unused Inputs that the
Trigger switches would be connected to. To have an alarm generated when the
switch is activated assign the Input a 24hr Time Zone.
Time Zone – Create Separate Time Zone(s) “A” for each group of Card Holders to
be controlled independently, and for each component that you want to control
separately. The Time Zone schedule is defined as to when it should work as
normal. Some of these Time Zones may have the same definition but need to be
controlled separately so they are defined separately. Select “Time Zone is OFF
when Linked to” for those that you want to shut down, or select “Time Zone is
ON when Linked to” for those that you want to force on. Remember when you link
to a Time Zone you will affect any and all things that Time Zone is assigned
to. Keep these Time Zones and Access Levels exclusive to what it is you want to
control and do not use them for anything else.
Access Levels – Create Separate Access Levels for each group of card holders whose
access needs to be controlled independently. Assign the Time Zones “A” to each Device
in the Access Level the Card Holders should have access to.
Linking Group – Create a new Linking Group “1” for each Time Zone “A” to be
controlled separately. Of the Components to link to under Time Zone, select the
new Time Zone “A”, assign a 24 hour Time Zone (unless you are wanting to
control when the link occurs) and a Response of “Follow”. Assign this Linking
Groups to the Virtual Outputs and select “Perform Link On – Secure” and/or
assign them to the Inputs where the Trigger switches will be connected.
Linking Levels – Create a Linking Level that associates the Device (readers to be
used to trigger the links) to the above created Linking Groups.
Operation – When the Virtual Outputs are “Secured” by manual command from the
Operator they activate a Linking Group that links the associated Time Zone – On
or Off. Tripping an Input into alarm can also trigger
the Linking Groups. When the Linking Groups are triggered their associated Time
Zones will be forced on or off thereby affecting anything the Time Zones are
assigned to.
The doors that are required to lock down would be assigned Time Zones
that are configured for “Time Zone is ON when Linked to” These Time Zones would
be defined in a Linking Group and set to “Follow” and the Linking Group would
be assigned to an Input or Virtual Output. Triggering the Linking Group would
force the Time Zones to be ON which would immediately secure the Outputs they
are assigned to. Devices (card readers) could be shut off where necessary by
the Time Zones that are assigned to them and Access Levels could be restricted
only allowing certain people access at certain doors.
Egress devices that unlock a door directly would have to be contended with
by possible activating a relay that physically shunts the contacts in the
device. Egress devices that signal the controller to unlock the door can be
configured so that the input 8 does not unlock the door but rather links to the
door Output. This link could then be controlled through the Time Zone assigned
in the Linking Group.
