    Default 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.

    I too would be interested to hear how this goes. Our new headquarters station will open in April, and I have been asked to find a way to install an old 12v "bubble gum" light from a retired rig onto the ceiling of the day room or dormitory, to activate when our tones drop. I have an ancient but functional desktop plectron which has an indicator light for when an alarm has been recieved. The plectron indicator has a manual reset button. I can hide the plectron in the attic above the dorm and play with relays and low voltage transformers to turn this indicator into a trigger for the bubble gum, but I need a way to make it automatically reset after five minutes or so instead of requiring a manual reset.

    Obtaining a one-strike bell or gong would go well with this, especially if it meant we could turn down the damn heart-attack Minitor tones.

    Maybe I should take this story to my local Radio Shack and see what they have to say....

    When our station was under construction to add the PD for a public safety building a few years ago, we had our radio service hook up a horn outside to tell the construction crew that we were coming in for a call and to clear out of the way.

    Basically it was an old Plectron we had laying around hook up to a siren box. A siren speaker was hooked to that and hung up outside. The plectron was plugged into the wall and between the siren box and the plectron, there was a timing switch that would allow the siren box to run for 2 minutes. The siren was turned on and left on hi-lo so when the power was activated to it it would go off. This timing switch was just a simple diode switch that you can find at Radio Shack. I'm not sure how they got it to do 2 min of activation though. Maybe they come in pre set times and just buy a 3 min switch or 4 min switch or whatever.

    As long as you put a switch between the Plectron and the gong or light or whatever, you should be ok. Wish I could be more help.

    Thanks Dickey. As I supposed, Radio Shack will have the answer. A very helpful reply, I appreciate that, sir.

    what about using a minitor and amplifier. The amplifiers have a relay built into them and with the pager it would be a tone alert system. Maybe look into that route. I know they make a bell for the Minitor IV amplifier, maybe you could go that route and just replace the bell with your gongs.

    The dripping irony of the fact that I am asking for advice regarding basic electronics - considering my username - has just dawned on me.

    By way of pre-emptive explanation.... my exposure to electricity is primarily the 8,000 - 500,000 volt AC variety. I don't have much history dabbling in the "little" stuff.

    the minitor amplifiers only activate the relay for whatever is plgged into them during the "alert period". My though would be to use that to trigger a relay that is on a instant on timed off relay. then set the timer to 5 minutes. Radio shak shoulc have all that stuff for ya..and then I would use a 120v to 12vdc transformer. those should be extra prevelant around in any electronics store and even probably walmart or something too.

    Mighrt try the folks over at Radioreference.com forums.

    Bunch of Ham Radio operators over there who are always hooking up tone decoders and what not.

    Not to pee on another post above, but my recent experiences with Radio Shack is that they only know cell phones and televisions.

    yeah very true with the knowledge at radio shack. However if you KNOW what you are looking for, usually they have it. I am pretty sure they would have a Timed off 5 minute timing relay for ya to hook up. I could draw up some schematics of how you would need to wire it if you need me to.

    lil story, I went into a radio shack asking for a variable current and voltage power supply one time. They pulled out a dc to ac power inverter for me. I told them no, explained again what I was looking for. They told me those dont exist. I said then how have I used them for testing before?????

    We use a plectron (remember those!) they were great, because they automatically reset. So, and i'm not electronics expert, we wired the volt output (there was a connection on the bacK) to a relay to a strobe light.

    As long as there was audio after alerting, the strobe would flash.

    I also believe that some minitor models (I know Min IV's) can also be wired this way and set to automatically reset.
    I am now a past chief and the views, opinions, and comments are mine and mine alone. I do not speak for any department or in any official capacity. Although, they would be smart to listen to me.

    Question Gamewell gong help wiring ???

    I do really appreciate the fast response from all the posters here. I think, after talking around the station, is that the “plectron” is the way to go for us. All we need is something to “trip” on and send the 12V signal to the gong when the tones drop. I’ll have to check Ebay for one. They were in the old station decades ago but we don’t have them anymore.

    DFD asked if our lights go on when the speakers trip. Yes they do. They are controlled by a complex “box” that has an enunciator panel and all kinds of 120V wires running to lights all over the station. We thought of tapping into this but it’s too involved. The union is attempting to find a way to “do it or selves” so that we don’t have to pay big $$$ to have the service guy come out and run wires all day from this brain.

    I do like the idea about the Minitor too. I could isolate the relay that trips when it detects our “alert” tone then use that to run the signal to the gong. However, I have no idea what that component looks like inside the minitor. Anyone know where it’s located? Or have a pic to forward? I appreciate the help greatly!

    Well your speakers and lights are powered through a relay panel somewhere in the station.Jump power off the speaker. Run that to a 120v to 12 vdc transformer and then conect your Gong. Doing this will "trip" the speakers, the lights and Gong. This sounds neat, old stuff in new stations. Hope you guys figure it out.

    Het DFD! That sounds perfect, the only problem is that when the speaker "trips open" and power is flowing to the speakers the gong will ring on every spoken word from the dispatcher I would assume. That would be VERY inconvenient LOL! I do see what your sayin' though it makes sense. I gotta find a way to isolate the inital "alert" tone to get something to trip at that particular point and that's it. Otherwise the gong would be ringing with all the radio traffic. Does this concern make sense? Thanks Jason

    You need a relay with an adjustable timer...it will only work with specific tone from the radio dispatch. The Timer will only set the gong off and will not affect the speakers....we set our timer to .0050 sec which tripped the bell every time the dispatch open the informer with a tone.

    The way I would do it for the easiest way...may cost a little more, but buy an amplifier for the minitor 2 or 4 or 5 or whatever it is you use. Then buy the accessory bell for it...then take the supplied bell of and attach the gong. easiest way, because that relay is internal and all you have to do is plug it in and it will sound the gong when the tones alert. then you dont have to worry about the gonging for every word and such...and no worry about being electronics experts...quick easy and not too expensive

    Default Youngstown, OH boards has section on Gamewell

    Check out this location. There is some really good info on how to properly hook up the system. All that you really need is a contact closure to start a timing circuit. The Gamewell is supposed to operate as a supervised system (a small current is flowing unless there is an alarm) When the circuit is broken it releases the striker. http://www.youngstownfire.com/forums...8183&board=3.0

    Fire Dawg's idea is good too. I would think Radio Shack might have this component? Thanks

    The amplified chargers for the Minitor Pagers have external contacts that you can tap into.

    You should be able to find all the schematics you need at www.batlabs.com

    You can search their forum for things like station & pager or station alerting and get some great info. but be sure to check out these two threads in particular.

    http://batboard.batlabs.com/viewtopic.php?f=1&t=34859

    http://batboard.batlabs.com/viewtopic.php?f=12&t=64836

    Based on the info in the second thread - you could probably frankenstine a MII pager and not even need the charger base if looks aren't an issue.

    If all you want is for the bell to ring once - that should be really simple. Making it ring more than once will be a bit harder.

    Good Luck.

    I did work for this place before I got on the FD. The company is out of Memphis, TN. They are a building automation company. Go to the web site and under Kele Catalog highlight "select section", scroll down to relays and contactors. Everything you need is there, and of industrial and UL quality. They have a butt load of electrical engineers, that are available to speak to.

    Just another idea.

    WHOA!!!!!!!!!!!!!!!!!!!!!!!!!!!!


    The gong wiring stays HOT all the time. It operates only when the circuit is broken.

    My advice it to contact Gamewell if they are still in business and or another fire department that still uses the gongs and get someone, probably from the communications section, that has the knowledge to help you out. At least if you had to pay them with a meal or transportation it would be better than burning up hidden wires in your station doing something that you know nothing about.

    Our station had what we called the "wooper". An electronic siren that was connected to the old plectron relay box that used to key the outside siren. It was mounted in the hall outside the bunk room and could be heard throught the station. Still there were guys who could sleep through that thing. Me (and a few others) usually snapped out of our sleep whenever a first due box was announced (the box # preceeded the tones in our dispatch).

    My grandfather was district chief in Lynn, MA. There was a Gamewell "tapper" in his house. I remember running over to the desk with the running cards when a box rang in to see where it was and who was responding.
