The FAQ Frequently Asked Questions The FAQFrequently Asked QuestionsQ: Where do you find these clocks?A: Some of my clocks have come from school buildings thatare being converted to another use, most typically apartments. I've founda couple in dumpsters on remodeling sites. The majority have been ebaypurchases. I usually search for 'standard electric' clock',with the 'standard electric' in double-quotes, and 'search title anddescription' checked. I tend to find more clocks that way.Q: The school I work at has aStandard Electric clock system, and we'd like to purchase new clocks for areconstruction project. Can you help?A: Yes I can. Drop me a,and I'll help you get brand new compatible clocks or used Standard Electricclocks from other schools.
I also fix impulse slaves as well, send mee-mail for more information.(updated 10/31/06) Q: Themechanical master clock at our facility has died after half a century ofservice, and we need to replace it with an electronic master clock. Wehave a Standard Electric Time impulse system. What master clock do yourecommend?A: I've hadexperience with several different electronic master clocks including theLathem X-128 and X-384 series, the Lathem Mini:Master (LTR-0), the Simplex 6400 MasterTime Control and the Applied Technical Services MC41. I also have a Standard Electric Master Time Programmer 1400 that was made by Faraday. The 1400 is an excellent master clock and I consider it to be top of the line. It runs two dissimilar clock types, has two bell circuits in the base model and does an excellent job at running the older slave clocks in that the impulse is three seconds long instead of industry standard two seconds. In addition, the 1400 corrects the AR-3 clocks properly by including a 'normal' impulse during the correction impulse, allowing any non AR-3 clocks (for example, a circuit of older series, non-corrective mechanisms) to advance normally through the minute.
The 1400 also can run two circuits of identical clocks on each clock type, which is great for the collector looking to run AR-3s, series and AR-2s. It can do all of them at once! The Simplex master (with optional impulse module) doesan excellent job running a Standard Electric AR-3 system.
I'm not sure of thepricing, but I'm pretty sure you have to purchase it directly from Simplex. The ATS MC41 (and presumably MC81) does a great job as well. Both executethe intended correction impulses correctly, the MC41 and the Lathem clocks issue a correction impulse ONLY during from xx:58 to xx:59 so if you're using the AR-3 correction method you have to be a little creative with wiring in series clocks.
It's compact in size, reasonablypriced and easy to install. And honestly, though I thoroughly enjoyworking on Lathem systems (they are well built), I've had problems with theLathem LTR-0. It likes to send out an impulse on both the main andcorrection wires at the same time, which doesn't allow the minute hand to freelyswing to:59 like its suppose to. I've sent e-mail to Lathem regardingthis, but I have not heard back from them as yet. I haven't had the same issue with the other Lathem master clocks, notably the 4-384 and the 8-128.If I were to recommend a new clock for your existing clock system, I would suggest a Standard Electric Master Time Programmer.Q: I have a Standard Electric clock. How much is itworth?A: I hear this question a lot. The best suggestion Ihave for coming up with a value is: watch ebay. See what the clocks are goingfor on there.
I've seen pendulum based master clocks go for as little as$400, yet as high as $2,000. I can help provide details on the ageand type of the clock if you send me pictures and as much background on theclock as possible. The wooden cased clocks are usually worth more than themetal clocks, and the master clocks are worth much more than the slave dials.Q: I hooked up a power cord and plugged the clock into thewall, but nothing happened.
How come?A: DON'T EVER DO THAT AGAIN! I repeat, DON'TEVER DO THAT AGAIN! The clocks you see on the wall in school, the oneswithout a second hand, are called impulse clocks. They DO NOT have thecapability to keep time on their own.
Plugging them into 110VAC householdcurrent is dangerous for you and the clock. Impulse clocks, or morecommonly, slave clocks, receive a low-voltage impulse from a master clock,usually located in the main office of the school or commercial building.This low-voltage impulse activates an electro-magnet in the clock, and thenreleases it when the impulse ends, causing the hands to advance oneminute. That's why you usually hear two clicks, one for magnet 'on', theother for magnet 'release'.
Plugging an impulse clock into 110VAChousehold current is a sure-fire way to destroy the clock, and puts you inimmediate danger of electrocution.If your Standard Electric clock DOES have a second hand, then itmay run on 110VAC. Be forewarned that some of the clocks ran on 24VACrather than 110VAC, so it may move really fast for a couple of seconds beforeit's fried.Always, always, always, get as much information as possible onthe clock in question before plugging it in. If in doubt, start with lowDC voltage (like two AA batteries wired in series) and go up from there.Send me e-mail if you have questions.
I'm more than happy to help you.Q: O.k., I have an impulse clock. How do I get it towork?A: You have a couple of options. Find yourself amaster clock (new or used) and run it just like they did in school. Or, goto my links page and find the link for the 'slave driver', a niftyelectronic device that will act like a master clock.Q: Why Standard Electric Time clocks?A: I think there's a couple of answers to this one.First of all, Standard Electric Time clocks were the first ones of this type I'dever seen, way back in kindergarten. To this day, I remember sitting onthe floor in Mrs. Mosher's room (Room 5) at then Pulaski Elementary School forthe first day of kindergarten, and noticing the clock clicking ahead everyminute. And whenever the clock clicked to 9:10, the buzzer buzzed.
Everyday, without fail. Then in first grade, I noticed that the clock was differentin that room, but it did the same thing, at the same time. I wasfascinated by it. In my later elementary years, we were taken to the high schoolfor six weeks each year for swimming lessons. I noticed they had clocksthat did the same thing, but they were made by someone else, and never seemed toagree on what time it was.
(A chronic problem of that clock system - itwasn't Standard Electric). As my travels brought me to otherschools, I noticed the other manufacturers of these clock systems, butStandard Electric seemed to be the most prevalent (with Simplex/IBM running aclose second). Standard Electric is the oldest manufacturer of theseclocks. I also like the looks of these clocks in comparison to other clocksystem manufacturers.Q: Why were you so hell bent on getting a clock from yourelementary school?A: A couple of reasons on this one too.
Simplex 2351 Master Clock Manual
First, it'sthe clock I remember the most. These clocks were a perfect compliment tothe architecture of the school. Secondly, as I've traveled and spoken tomany other people about Standard Electric Time equipment, I've come to therealization that this particular style of clock may very well have been custommade for the school. I've never come across another school with this type ofslave clock.
Jeffrey Wood, who has done many, many years of research onStandard Electric has never come across any design schematics for this slaveclock, and has never seen this type of slave clock before. Since theclocks in my elementary school were recently replaced, it was the perfectopportunity to get one of these clocks, and it may be one of the last completeclocks in existence.Q: My question isn't here.
