Excalibur question

[EHFD_Tower_751]

Im sure this is a quick negative, but i’ve wondered something about the excalibur and could never find an answer regarding the topic.

I know the mx7000 was offered with one, but was the excalibur ever offered as a speaker center option?? Ive ever seen it as an all light bar, unless ive missed something (be my luck i have).

Only asking cause i have a frame, lower outer domes and some internal lights and mirrors for an excalibur bar and want to use them.

Also a little off topic, but are the lowers for a 36” bar different from the lenses with the lips on a 47” bar??

Yes. https://www.qualityemergencylights.com/code-3-excalibur-lightbar-p-2441.html

Hmm wonder how hard it is to find one, ive never seen one.

Would be a nice addition to my collection, all my excaliburs are all lights

And for tsquale, thanks for that site and do you understand this sentence....

• Three non-activating inputs for low power, ptohocell, and BTT cutoff

Any idea what a ptohocell is used for??

LOL

Yeah I know I was hoping he'd get a laugh, I saw a lot of typos on the site but that one had me laughing!

A ptohocell's job is the opposite of a photocell.

So your saying it uses moonlight to activate??

I have the bottom bar in the photo (minus the hot feet). 8 upper prism LEDS, 4 lower corner strobes, 4 front lin leds, 4 rear torus leds, alleys, speaker grill, with a custom code 3 center speaker specifically for that bar. In NOS condition. Just incase someone might want it.

roof top sirens have been "outlawed" for awhile any siren grill for a MX will fit a excaliber as they are the same exact bars minus the lower "half"

Siren speakers in bars are still heavily used in Europe, and still in a few places in the US (stupid I know). As far as the other part, the MX and Excalibur speaker grills are completely different and its because of the bottom section. Both speaker grills cover the top and bottom sections of the bar and mount differently. They are not compatible.

 

[Jarred J.]

so the chrome speaker grill is a one piece section and not 2 individuals like the rest of the domes?

yes all code 3 speaker grills are one piece, XL, MX, and Excalibur’s. There was one small exception in the early 90s when they made an mx7000 speaker section that didn’t cover the bottom of the back dome for the arrow stick. That didn’t last long as they converted to all light versions shortly after.

 

[Jarred J.]

good to know

Yes I remember driving a Mexican police truck when I was 17 and it had a Excalibur with outer rotators and center strobes and a center speaker.

Why are roof speakers "outlawed"? And what about the photocell???

 

[Sparky_911]

NFPA standards are part of "outlawed" roof sirens. Excess noise in the cab distracting operators which cause accidents. Several large PD agencies and independent govt agencies (OSHA types) have also done studies showing they're no bueno.

I've never seen a photocell on a halogen bar. Edge strobes and LED but not halogen. I dont know how they would even function on that type of bar.

 

[d119]

Perhaps for the TA intensity?

Are you sure it is a photo cell and not a solar cell.
