Found this on eBay. First off, the strobe does have the 7002-style font on it. Second, note that the sounderplate does appear to be black. And third, note that the grille is of the vandal-resistant type! There’s also a pic of the back of the alarm, and it clearly says 7002-24 on the horn. I don’t think the horn was taken out and put in a new alarm because as to my knowledge, the horn doesn’t come out. Could this may be an “interm” alarm made between the two series? Very odd…

Also note there’s wire leads instead of screw terminals.

Man, that guy is a ripoff. $39 for an alarm that old is outrageous!

Hey, I got my NIB 7002T for a bargain compared to what other people wanted. There were two auctions up for used ones and they ranged from $50-$70. Now THAT’S outrageous!

Yes. Wheelock made those in 1985 when they began to shift their product line to the “T” series. That seems to be the only year they were made. They also changed their name from “Wheelock Signals Inc” to just “Wheelock Inc” that year.

The way you can tell is by the date code on the back. It’s stamped “2885”, meaning it was manufactured the 28th week of 1985 which happens to be sometime in July. Almost all Wheelock products use this dating method.

Here’s what I found out in recent years.

  • The “T” in the model number means there are screw terminals instead of wire leads for power-up. And that’s the only difference between the 7002 and 7002T. It has nothing to do with the grille.

  • Both wire lead and terminal versions were released at the same time; for that reason, they were given different model numbers.

  • Shortly after the grille redesign, Wheelock discontinued the regular 7002 since they figured terminals were easier to wire-up; and that’s why you usually see the “T” models with the closed grille.
