    Gamewell station Gong! Need wiring help

    Looking for some tech savvy members! My dept built a new state-of-the-art HQ that does NOT include a pole or other “cool” traditions from the old days. Bummer. Anyway, we did manage to bring our old Gamewell turtle gongs, tickers etc to the new facility. We have a large oak display cabinet in the day room to display the old helmets gongs etc to the public.

    The members are looking to find a way to get he gamewell turtle gong activated again. My department is combined now with the PD and the dispatch center is located in the same building for both depts. The new dispatch “console” was not wired for “the bells” as it was in the old station.

    We are looking to get the turtle gong back into service without running wires and relays to the dispatcher console. It would involve breaching concrete walls obtaining power sources etc and the Town is not going to pay for that just to get some bells ringing again.

    Does anyone know if there is a “tone activated” DC relay or something that could be wired into the gong to ring once when our station tone is activated? We thought about retro-fitting an old Minitor II and wiring it to a relay or something. The station gong is an early brass Gamewell unit that is 12 inches and uses 12V DC. We’re just looking to get it to “gong” once when the station “tone” hits. Anyone know of any economical way to accomplish this and what hardware will be needed? Thanks for the help.

    hello, I am currently restoring a SAFA street box (Gamewell competitor), and I plan to hook it up to a bell/gong. I can't find any Gamewell gongs or bells though. I have seen videos of people converting Simplex or other fire bells to ring the box code, but I don't know how to wire that. Also, I know the boxes run on 12 volts DC 100 Milliamps, but does that change when you add a bell to the loop? Any info helps. Thanks

    Exactly what you need in a receiver, and probably cheaper than any of the other solutions.

    If you want to get really carried away, set up a motor with a wheel and switch (like the Gamewell's used) to bang out your station number...

    There are some directions up for auction on E-bay under Gamewell fire alarm. If that does not help I have some instructions that I aquired to do the same thing you are doing except I am putting this system in my private ffrie museum at my place. I can try to copy what I have and send it to you.

    Another Option

    You might consider a Federal Signal Informer http://www.federalwarningsystems.com....php?prodid=25

    I used an external repeat cycle relay and diode to protect the contacts in the Informer.

    Awesome News - Knew you could make it happen if you stuck with it long enough. Glad you got it figured out.

    what i would do to prevent the magic smoke escape is wire the relay in the amp to another hard mount relay control switches..then the full power of the end load is going through the big relay and the little relay is just being used to trip the big relay

    Gamewell wiring issues UPDATE

    Again thanks to all who keep reading my amateur BS problems and continue to offer their time. I do appreciate it. I have finally wire this beast according to everybodys drawings etc. The 2nd and 3rd pin is where I want to be to supply the power for the coil on my relay when the charger contacts activate. Everyone, including myself, have assumed that I have Motorola amp charger model NRN3041A, 3042A, or 3044A. These all have the 6 pin accessory port on back. All the posted lierature clearly shows pin 2-3 as the "dry contact"

    Here is the Million Dollar F-up on my part. The Motorola Amp charger I have is Model NLN4985. Yes I do have the accessory port on the back for a DIN connector only it has 5 pins not 6. With this new correct wiring as stated above, I believe that my models pin 2-3 are NOT the dry contacts because the unit will not trip my relay still. Also I get feedback out of the chargers main speaker when I hook DC power to pins 2-3. If we assume 2-3 are open till the tones activate it, there should be no reason to be getting any feedback from the base unit (open closure NO current flowing right!). This is why I think the "dry closure" might be different pins on my charger.

    So I'm now trying to find different combinations for this other that just 2-3. Anyone have any pin assignments for this particular unit that isolate where the contact closure is for the NLN4985. Again Thanks for all your time.

    P.S. I hope this S^@! isn't on my Lt's test comin' up

    O.K. - here's my thinking on this and I will admit I have never actually rigged one of these up - I'm working solely on theory and the information I have available.


    1 - the internal "relay" in the base most likely isn't a true relay but rather a series of "switches" built into and IC chip somewhere

    2 - the 10 watt @ 28 Volts works out to be about 1/3 of an Amp current capacity. Recalculated for 12 volts that equals about 0.8 Amps current capacity.

    3 -

    That being the case - if the Gamewell gong draws less that 0.8 Amps in this configuration, then everything is groovy and he can wire directly through the base contacts as you suggest - otherwise the base is most likely going to experience a sudden release of the "Magic Smoke" and cease to function.


    That being said - as I went back through all these threads and re-read that the Gamewell gong is also 12VDC then the above diagram could be modified slightly to the following.



    For the added cost of the single extra relay - a little "over engineering" is cheap insurance in this case.
