Summary alarm module, physical interfaces
This section describes the connections between your
ViaLiteHD
modules and the Summary alarm module. There is no need to install any
interface cables between summary alarm module and connected modules, as these are all connected via the rack chassis backplane.
Please read fully all relevant documents for information on installing your
ViaLiteHD
equipment before commissioning your system.
Module operation, 7HP standard plug-in module
All
ViaLiteHD
plug-in modules are hot-swappable, so it is not necessary to power-down the rack chassis before inserting a module. All
electrical connectors are retained by the module. So it is necessary to either disconnect any cables or have a sufficiently long service loop.
To install a 7HP Standard module
Push the release button of the module handle down and simultaneously pull the top of the handle forwards.
Align the module upright and perpendicular to the front face of the rack chassis so that the PCB
slides into the “crow’s feet” card guides
top and bottom.
Gently push the module down its guide, applying pressure via the handle, you may also apply pressure between the LED and buzzer.
As the module is fully mated the top of the handle should snap back and lock in position.
The pawls of the handle should be fully engaged in the matching slots.
If power is applied to the rack chassis the module power LED should light as soon as the module is fully inserted
Connect any interface cables
To remove a 7HP Standard module
Disconnect any cables if necessary
Push the release button of the module handle down and simultaneously pull the top of the handle forwards.
Apply pressure via the handle and gently withdraw the module from the rack chassis.
