Hi, We are in the process of installing a Vertec system powered by Crown I-Tech amps in our theater.  We must meet certain fire codes, one of them being, the sound system must be able to mute automatically when a fire alarm is ativated.  Is this being done through the IQ Network by anyone, and does it meet fire safety codes? (located in N.J.)
Thanks!

Well the answer is yes and no.

With a computer on the system (running all the time) and at least one CTs amp, with a PIP card, you can use the AUX IN connections of the PIP's RJ-11 to trigger an all mute of the amps via the IQwic software. The ITechs do not have a prevision for an Aux Port but can be muted by an all mute command from the software.

If you are using anything like a BSS London Blue as FOH processing you can have it muted by the fire alarm relay as well.

Another alternative is to use something like RDL relays in line with the audio path.

As to what would be excitable in your location only the local Codes Enforcement Officer would be able to answer that. We have seen several times were each CEO has his own interpretation of the codes and what he wants to have happen and how.

David,
I too am trying to connect a fire safety system through use of a PIP Lite's RJ-11 trigger. I am not aware of how you trigger an 'all mute' via the IQwic software. Am I missing that in the manual. I can make the circuit mute when one amplifier it is connected to it; however, if I daisy chain all the Pin2s together and all the Pin5s together and connect the fire safety circuit to the first Pin2 and Pin5 the system un-mutes (theoretically an open circuit would remain until Pin2 and Pin5 are shorted by the fire safety circuit). Somehow through the 'daisy chain' process the circuit is completed. How can I have a single PIP signal an 'all mute'? Can it be done by a 'Lite' or can it only be done through a USP3?

It can be done wih a PIP-Lite, USP-3, USP-3CN or a Muti-Channel CTs with the USP/CN module.

There are a few things to consider with this. Fist the computer will have to run 24/7 so it will need to be on a UPS power backup. Second after the finalized IQwic file is done the file will need to be placed in the computers startup directory. This needs to be done so that if the computer is rebooted the operational file will restart automatically.

Also the amp that has the Aux port of it’s PIP card being use would need to be on a 24/7 AC outlet.

To have all the amps mute in a system, including amplifiers that do not have an aux port, they have to be told to do so from the software.  The way to do this is to create a “Scene File” that has all the amps muted and recall that scene file from the Aux port of a PIP card.

Connect to the system using the IQwic software. Verify all the component show up in the Workplace screen

1)   In IQwic on the Main Menu go to File|Edit Scenes.
2)   In the top left of the “Scene Editor” window there will be several buttons. The fist button on the left has a blank sheet of paper with the corner folded over. This is the “Create a new Scene” button. Select it.
3)   Once it is selected the list of components in the “Available Component” window will go from gray to black text.
4)   Highlight all the I-Tech amplifiers that need to be muted by using the standard window commands of ctrl-left click or shift-left click. Once the amplifiers are highlighted the “Available Controls” will be listed in the bigger of the two panels.
5)   To make it easier to find the mute functions type “*mute” in the smaller of the two available control panels and all the mute functions will be listed in the bigger of the two panels. Using the standard window commands of ctrl-left click or shift-left click highlight the “Channel 1 Output Mute Enable” and the “Channel 2 Output Mute Enable” and select the “Add Controls” button to add them to the “Controls in Current Scene” panel.
6)   Highlight the PIP-Lite cards and because the “*mute” was the last search the mute controls for the PIP-Lite module will appear in the larger “Available Controls” panel.
7)   Highlight the “Channel 1 Input Path Mute Enable” and the “Channel 2 Input Path  Mute Enable” and select the “Add Controls” button to add them to the “Controls in Current Scene” panel.
8)   Highlight all the listings in the “Controls in Current Scene” panel. A drop down panel will appear. Use it to select “On” this will set the mutes to be On when the scene is engaged.
9)   The third button from the left, in the top left corner of the Scene Editor, looks like a sheet of paper with an arrow taking it to a floppy disk. This is the Scene save button. Select it.
10)  A Windows save window will open. Give the scene a name that will indicate the scene is an all mute and select “Save”.
11)  Highlight all the listings in the “Controls in Current Scene” panel. In the drop down panel select “Off” this will set the mutes to be Off.
12)  Follow step 9 and 10 and save this second scene with a name that indicates it is a Mute “Off” scene.
13)  Close the “Scene Editor” window

The next thing to do is setup the software so that it is looking at the Aux Port of the amp being used for the interface, to the fire control system, and will engage the mute scene.

1)      In the IQwic main menu select Setup|System Aux and the “System Aux Setup” window will appear.
2)      Select the “Add” button and a line of entry boxes will appear in the center panel for each column header.
3)      Left Click on the blank “Component” box and a drop down arrow will appear. Select the PIP card and firmware version being used.
4)      Left Click on the blank “Addr” box and a drop down arrow will appear. Select the IQ address of the PIP card being used.
5)      Left Click on the blank “Monitor” box and a drop down arrow will appear. Select the “Aux Input”.
6)      Select the “Restore” box. This will allow the system to return to its operational state, before the mute scene was engaged, when the voltage is removed from the Aux Input. If the fire inspector requires a manual reset do not select the “Restore” box and Follow the section below to create a software button to recall the mute Off scene.
7)      Left Click on the blank “File Name(When High)” box and a button with three dots will appear. Select the button and a window will open.
8)      In the “Select Dataframe or Scene File” window navigate to where the On Scene is stored and select it and then the open button.
9)      In the “System AUX Setup” window select “Close”.

The software is now ready to mute the system when there is a voltage on the Aux Port of the PIP card. (make sure that you do not have the AUX port setup to directly do anything from it’s own control window. It should be set to “Do Nothing”)


If the Fire Inspector wants a manual reset:

*Create a Trigger on the Workplace screen and right click on it.

*Select Object Control List” from the menu.

*In the “Object control List Editor” window there is a small drop down window on the middle left. Select the arrow.

*In the drop down window select “Engage a Scene” and then hit the “Add” button.

* AN “Open Scene” selection window will appear. Navigate to where the mute Off scene is at. Select it and then the “Open” button.

*The trigger on the workplace screen is now set to turn all amps back on.





Save the IQ control file and place it in the Windows Startup directory.
