Vanderbilt SPC and KNX: arm, disarm and follow the alarm on the bus

Link’nX web: KNX gateway table of a declared Vanderbilt SPC bridge
The Vanderbilt SPC gateway table in Link’nX maps KNX group addresses to the commands and states of an SPC intrusion panel: arming and disarming the panel or an area, inhibiting a zone, driving an output or a door, and the mode, alarm and opening feedback. The rows follow what was read from the panel.
Intended for the authorized installer or administrator. To start a scenario on an alarm event, follow the Vanderbilt SPC actions and triggers guide instead.
Before you start
Section titled “Before you start”- An SPC Bridge declared in Link’nX, with the panel’s content read and then saved. Without this reading, the table only presents the panel rows.
- For the commands: the Link’nX sends commands to the panel box checked in the declaration, with a panel user whose profile allows what the bus must control.
- The KNX group addresses validated for the project.
Open the gateway table
Section titled “Open the gateway table”In Link’nX, check the project and the gateway. Open Devices → Security & Access → Vanderbilt SPC and find the right bridge. Click the two opposite arrows, whose tooltip is Gateway mode configuration, to the left of the Edit pencil.
The table presents the panel rows, then one set of rows per area, zone, output and door read from the panel. Each row starts with the element concerned, with its number and its name, for example “Area 2 (Upstairs)”. Panel means all the areas at once. The common operation of the table (filters, addresses, automatic filling) is detailed in the KNX table guide.
Map the commands
Section titled “Map the commands”The Actions tab presents the commands sent to the panel.
| Element | Rows | DPT | Value |
|---|---|---|---|
| Panel | disarm, part set A, part set B, full set, full set, bypassing open zones, delayed full set (after the exit time), delayed full set, bypassing open zones, clear all alerts | 1.017 | 1 sends the command. A 0 does nothing. |
| Area | The same seven arming and disarming commands, for this area only | 1.017 | 1 sends the command. A 0 does nothing. |
| Zone | inhibit, remove the inhibition, isolate, remove the isolation | 1.017 | 1 sends the command. A 0 does nothing. |
| Door | open momentarily, open permanently, back to normal mode, lock | 1.017 | 1 sends the command. A 0 does nothing. open momentarily only works when the door is in normal mode. |
| Output | on / off | 1.001 | 1 switches the output on, 0 switches it off. |
Only the output is driven on and off on a single address. For all the other commands, plan one group address per command: one address to arm, another to disarm.
Map the status feedback
Section titled “Map the status feedback”The second tab, marked by a speech-bubble icon, presents the states that Link’nX writes on the bus at every change.
| Element | Row | DPT | Value |
|---|---|---|---|
| Panel | bridge connected | 1.011 | 1 while the gateway is connected to the bridge and has read the panel. |
| Panel, Area | arm mode | 5.010 | See the table of modes below. |
| Panel, Area | intrusion alarm, fire alarm, tamper | 1.005 | 1 while the alarm or the tamper is active. |
| Panel, Area | fault | 1.005 | 1 while a fault is active: a zone input neither open nor closed. |
| Zone | open | 1.019 | 1 open, 0 closed. No value in the other input states. |
| Zone | alarm | 1.005 | 1 while the zone is in intrusion or fire alarm. |
| Zone | tamper, fault | 1.005 | 1 while the tamper or the fault is active. |
| Zone | inhibited, isolated | 1.001 | 1 while the zone is inhibited or isolated. |
| Output | state | 1.001 | 1 on, 0 off. |
| Door | door mode | 5.010 | 0 normal, 1 locked, 2 unlocked. |
An area’s alarm gathers those of its zones, and the panel’s alarm those of its areas. Link’nX also answers a read request from the bus with the last known state; as long as a state is not known, it does not answer.
Arm mode values
Section titled “Arm mode values”| Value | Mode | Available for |
|---|---|---|
| 0 | Disarmed | Panel and area |
| 1 | Part set A | Panel and area |
| 2 | Part set B | Panel and area |
| 3 | Full set | Panel and area |
| 97 | Part set A on some areas only | Panel |
| 98 | Part set B on some areas only | Panel |
| 99 | Full set on some areas only | Panel |
The values 97, 98 and 99 indicate that the panel’s areas are not all in the same mode. When the whole panel is armed or disarmed, its areas change one after the other: Link’nX waits 2 seconds before writing 97, 98 or 99, and writes a mode common to all the areas without waiting.
Save and reread
Section titled “Save and reread”- Fill in Address and check Active for the planned mappings.
- Save each tab with the floppy disk at the bottom right and wait for Succès (Success) and Données sauvegardées avec succès ! (Data saved successfully!).
- Reopen the gateway of the same bridge to reread the addresses and the Active boxes.
Check the result
Section titled “Check the result”- First check that Panel: bridge connected is at 1 on the bus.
- Send one command at a time, then check its effect on the panel and on the matching feedback, for example arm mode after arming. The bus receives no confirmation of the command itself.
- Open a zone or change the mode from a keypad of the panel, then check the feedback on the bus.
Troubleshooting
Section titled “Troubleshooting”A command has no effect. A refusal by the panel does not appear in Link’nX: insufficient user rights, wrong password or PIN, zones open at the time of arming. Check in the declaration that Link’nX sends commands to the panel is checked, otherwise the command goes out without a user, then the panel user and its profile, and finally the active mapping. Also check that the address does receive a 1.
The value 0 does not disarm. Each command is sent on a 1; the 0 of an arming row does nothing. Map the disarm row to its own group address.
An area, a zone, an output or a door is missing. The table follows the list saved in the declaration. Run Read from the panel again in the bridge record, save, then reopen the gateway.
The panel mode goes through 97, 98 or 99. Its areas are not all in the same mode. Use the arm mode row of the desired area for a precise state.
No feedback arrives. Check Panel: bridge connected, then, in the declaration, the bridge’s Events account. According to the Lundix manual, the panel reports no event to the bridge while it is in Full Engineer mode.
If the problem persists, contact support@can-nx.com with the model of the panel and of the bridge, the row concerned, the value sent or expected and the attempts made, without a password or PIN.
