Mark X siren help

[dcsru]

Morning,


I was digging around and came across couple sirens in an old cabinet. I have seen before or google'd all them except the "Mark X" one. What would this normally go in??

OMG!! I youtube'd it and that thing sounds so different than anything we have in DC. I gotta get this put into my crusier as a second siren!

SP sirens were primarily used in New York City by the PD and EMS back in the 70's into the early 80's. I believe that some of the Signal Stat sirens of that era were actually manufactured by SP.

Does any one have any instructions/install manual or pinout guide on this?

I think I have some pin out info on the Mark VII's. My guess would be that the harness would be the same. Let me see what I can dig up.

Great, thanks! It doesn't have the harness on the back so it looks like I will have to put something together

SP sirens were primarily used in New York City by the PD and EMS back in the 70's into the early 80's. I believe that some of the Signal Stat sirens of that era were actually manufactured by SP.

The NYPD began using Signal-Stat sirens when they switched from mechanical sirens to electronic sirens for the new blue and white scheme in the 1973 model year. From this point to the late 70's each model number in the product line 1-10 had it's own unique sound- pitch, speed, etc, and the model numbers tended to correspond to the type of vehicle they were installed in- pct RMP, Highway Patrol RMP, ESU REP, if one recognized the difference in sirens, one could tell who was coming.





In -'77 or '78, they standardized on the 'Stat 7' for precinct RMPs (patrol cars). In the early to mid 80s, Scientific Prototype, a company located in Harlem took over production, I guess they were licensed to, and rebranded the model nonmenclature to the "Mark" series, with the MARK 7.





The Stat 10/MARK 10 was simply a combination siren and switch unit that I don't recall was ever used in precinct RMPs but was possibly used in ESU REPS. I know Yankee also started producing the same sirens at some point later, maybe Dietz did too. Scientific Prototype retooled to digital technology to meet NYPD-spec for the 1990 vehicle model year but were rejected in favor of the FedSig PA300, so losing their largest and primary account in the NYPD, they went out of business not long after.

Just saw your reply. I will go through some email and documents tonight.


While we are on the subject, I have a Mark VII, but it is not the NYPD version. The siren button operates like a standard tap two or 5 second yelp button. It does not instant on or off. Anyone know how to convert it?


OR.........


My Mark VII is NOS. Never been installed. I would trade it for a good condition version X.

This is for the Mark VII - I would think they would keep the harnesses the same, but not sure.


Pin 1 - Red Battery +


Pin 2 - Black Battery -


Pin 3 - White Single Speaker


Pin 4 - White Single Speaker


Pin 5 - Yellow Remote Switch For Yelp


Pin 6 - Blue Horn Relay


Pin 7 - Gray Horn Ring


Pin 8 - Green - Radio Re-Broadcast


Pin 9 - Green - Radio Re-Broadcast


Pin 10 - Orange - Aux B+ Ignition

The timed-yelp was the standard configuration, the momentary yelp was NYPD-spec. You have to cut a resistor or diode on the board to obtain the momentary yelp, it's been too long for me to remember where and which one it is.

Lots of great info!! I am gonna test her out then try to find a spot to mount it where the MDT won't be getting in the way.

Actually, the 1976 or 1977 model year Pontiac LeMans Enforcer RMPs had a compact Signal-Stat 10 style toggle-switch siren model mounted into the am/fm radio cut-out of the dashboard, I don't know exactly what model # it was.

I know your post is old, but any chance you still have that mark x and ready to let it go?

I'd love to have that Smith & Wesson Magnum V. It's the earlier version with the deep slow rising wail and yelp tones. The early Smith & Wesson Magnum series sirens sound very close to the late 1960s Federal Director and Interceptor sirens.

Hi gang and thanks for all the information. I notice there are two slide switches inside on the circuit board. One I would imagine is for the 50 watt / 100 watt out put. Any idea what the other small slide switch is ???

There are three slide switches on the Mark VII PC board:

Switch at the rear of the board is 58/100 W.

Switch at the front left (directly behind the function selector) is a three-position slide that disables either the wail or hi-lo tones. Center is normal operation.

Switch at the font right is horn ring polarity.

MtnMan's post referred to the Mark VII siren, but I'd like to think that it and the Mark X are similar. (Posted this here as well in case anyone looking for the info finds this post and not the other one.)
