    Default LPP alert tone and in-cabin warning LED?

    Hi everyone,

    I just "mocked" my LPP install - prior to a full install, I like to lay out the wiring and test the hardware, a "mock install," if you will.

    Had a quick question on the LPPs warning tone.

    I'm testing out the LPP using the Laser Tester sold on Roy's commercial site. It seems to trigger the LPPs heads into firing - from my standard digicam, I can see the diodes "activating and remaining lit."

    However, I'm getting something strange on the other end.....

    When I activate the Tester, the in-cabin the alert LED goes to "blank" - not green, not red, it just "blanks out."

    At the same time, I do not get an alert tone.

    Defective alerting?

    Or is the Tester somehow not able to fully trigger the LPP, thus causing artifactual problems?

    Thanks!

    This somewhat applies to your other post
    The tester uses LEDs, the laser guns use diodes. The LPP can probably tell that it isn't a laser gun, so it doesn't trigger fully. Although the tester's pulse rate is consistent with a laser gun, the rate might not be as exact or as stable as an actual laser gun, and the pulse duration would be much longer.

    Thanks yet again, professor Jim!

    Looks like I'll have to call in a favor from a friend of mine to truly "get tested."
