The pull station is a Grinnell Model 1t. It is an older type of manual station, but I’ve searched the internet; And I didn’t find a key. If anyone could help me, I would really appreciate it.
Can you post a picture of the pull and the lock? That way we can get a better idea of what you’re looking for. Thanks!
I’m not really sure how to post an image. Here’s a url to where I Bought It from: <LINK_TEXT text=“http://www.ebay.com/itm/141651740152?_t … EBIDX%3AIT”>http://www.ebay.com/itm/141651740152?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT</LINK_TEXT>
The pictures on that link are a bit blurry and i cant read the numbers on the lock. I think i have a spare of the key you need, i just want to make sure.
Can you take a photo of the lock close up? Then just upload it here by using the “attachments” feature on the reply forum.
If you have one already, try a CAT-45. Don’t buy a key until you are sure, however.
Without looking at the picture, i think it may use a CAT45 or T45 key. However, i could be wrong!
Pretty sure it uses an LL805 key. But, check to see if there is any indication on the device or in the manual that lists what key it uses.
It won’t be T45. That’s a pretty long key and it looks like a shallow lock being on that thin station. CAT 45 could be a possibility.
Well I will be posting a picture as soon as it comes in the mail. I just thought maybe I’d be able to figure it out before it came. Although I do see the numbers on the lock. I ordered a cat 30 simplex b key a few days ago thinking it might work. If it doesn’t, all well. Thanks for the help everyone. As soon as I get it in the mail and out of the box, I will post a up close picture of the lock.
By the way, attachments doesn’t seem to be working correctly right now. It failed each time I tried it in a post I made a few days ago.
That’s a good key to have anyways, works in all Simplex “T-Bar” model pull stations, panels, and a few other devices here and there. You’ll likely need it eventually if you plan on expanding your collection further.
Simplex and Grinnell are both fire alarms companies branched off of tyco. That’s why I thought a cat 30 b key would work.
Mine takes an LL805 key, which if you want to buy one, can be found for $2.75 at
The seller just contacted me and the lock number says LL805. So the edwards key
Tyco bought simplex long after they standardized on a cat30 key, it’s the first key i would have tried and always a good one to have around even if it doesn’t work on this pull station.
My old Simplex key is a ‘B’ key. Worked on every Simplex panel or pull station I’ve ever seen (29 years). I only have one (lost many. many keys in my day).
I now have the correct key, but there is another issue. Now the alarms activate when the pull station is not pulled and deactivate when it is pulled. Does anyone know how to fix this?
It might be a normally closed type station. Many old systems used normally closed devices. Do you have a meter?
cat30 is another name for the simplex B key!
