If I were to put a heat detector in the attic what would the temp have to be because system sensor sells 135 degree and higher. Also what would the temp be for one in the kitchen above the stove.
For the attic, go with a 194 degree heat detector. At least around here, it’s not uncommon for an attic to get in the 135 degree range in the middle of August. I’ve actually gone on a couple of service calls to replace popped heats put in by other companies because the attic got too hot. If a fire breaks out in the attic, that 59 degree difference isn’t going to matter. Go rate of rise for a little extra insurance.
For the kitchen, you’ll be ok with the 135 degree heat detector - and I really wouldn’t go any higher. If your ceiling gets up to 135+ degrees, you have problems! Let’s put it this way, residential sprinklers are rated at 155 or 175 degrees. I would suggest going with a fixed temperature unit (System Sensor 5603) instead of the rate of rise if placing it fairly near the stove. I have a 135 fixed in my kitchen (it’s not in line with the stove either but fairly close, if you are standing back from the stove it’s about 6 feet to the right) and in 10 years I’ve never had it pop from opening the oven door.
I wasn’t aware they still made ROR only heats. I thought it was all combo now! 
Do you know some of the newer (or older) ROR only heats?
You can PM me if you want, to prevent getting too far off topic.
Well they are fixed temp AND rate of rise combos. The fixed temp portion is assumed, so why I left it out I guess!
So it can go anywhere in the kitchen on the cieling. I have a cieling fan in the center.
Also I said above the stove because there are marks of an old one that was connected to an old security system mounted there.
I would avoid directly above the stove. Move it off to the side just to avoid any problems. Idealy, centered to the room, keeping in mind the spacing listed by the manufacturer. As far as the old hole is concerned, some vinyl spackle works great for filling that.
Thanks I’ll put it in the middle.
I know that time has more then slipped since the last dialog, BUT I felt the need to add one more item, if only to fill in a misconception or seven ;0). THERE IS ONE VERY GOOD REASON TO GO WITH THE “ROR” [rate-of-rise], and that is that the non ROR units are considered as a “one use only”, which means that you have no way of knowing if it’s gonna work. On the other hand, the ROR units can be tested in the field [or your kitchen, et al]. In sum, the ROR is resettable. Personally, I’d prefer to spend a few bucks more [< $7.00] for the ROR. Disclaimer: I can only speak for the brand I recently purchased on-line with the big A-Z outfit. The brand I chose was “System Sensor”. BTW…I’m not promoting that brand, nor am I receiving any monies… This is simply about informing based on my search criteria.
