How does a 12-Volt Trigger Work?

Many people are not aware of the 12-volt trigger (aka. 5-12 volt trigger). It is a useful item that allows the end user to coordinate the projector’s power cycle with the drop and rise functions of their electric projection screen. The discussion below covers the easy process of installing this device that typically comes standard with Elite’s various lines of projector screens.

*The discussion below is based on actual chat transcripts with the omission of any personal/confidential material to protect the customer’s privacy. An example in this case is to change the contact’s identification name/number to “Customer” or a generic name.



[17:43] Customer: How does a 12-volt trigger work?  Does it control the screen’s drop? Will the 12v trigger work when spliced in with a mono cable that has a single wire with a bare shielding around it?

[17:44]        Jaime: The 12-volt trigger is a mechanism that allows your projector’s power cycle to coordinate with the projector screen’s drop and rise functions.  When the projector powers on, it signals the screen to drop.  When the projector powers off, the screen retracts back into the casing.  Also you are correct that the 12-v trigger is spliced into the mono cable.

[17:44] Customer: I have a Electric100H (Spectrum) projector screen.  Does that change anything.

[17:44]        Jaime: Your screen is perfect for this.  It’s designed to work with this trigger but yes, be sure to use a mono connection.  Here is the instruction diagram:

[17:44] Customer: Yes. So the red wire to the protected internal wire and the green to the loose shielded?

[17:44]        Jaime: Yes, that is correct.  Here is the full video to affirm that you have it right:

[17:45] Customer: just wanted to confirm. Is there a limit to the length of wire that the signal will travel?

[17:46]        Jaime: Not really. You can extend it by as much as 300' and still give a good signal. 25’ is more than enough to cover the adequate throw distance.

[17:47] Customer: Oh, ok. I'm using a 25' line so I should be a perfect fit. Thank you. I will be trying to hook that up tonight then.

[17:48]        Jaime: Sounds good.  If you need anything else, don’t hesitate to reach out.

[17:48] Customer: Thanks Jaime, I’ll do just that.

[17:48]        Jaime: Glad to hear it. Thank you for choosing Elite Screens

[17:48] Customer: Thank you
