Will this detector fit/work with the First Alert Wall Bracket that I have already installed for the SCO1N? Hate to put more holes in my ceiling.

They sent me the WRONG detector when I ordered, so I ended up having to drill a new hole in my ceiling to hold the new base.

If you are using this as a replacement for the same/similar model, no issues.I am not sure what your question is regarding the pack size.Do you need one or 2 Smoke Detectors?

Sorry, I misunderstood the question. The quick release button on top of my Escort still works and is accessible, if you adjust the mount at its lowest vertical setting. If your detector has an additional rear-facing sensor, you'll want it low enough to give that sensor a clear field of view anyway.

Yes it will work fine as I have one on mine.As long as you buy the base unit for letting you know somebody has entered or left the alarm part of it

This item didn't work at all for me, I returned it and got the First Alert sensor which works great but I believe can only be used vertically. You may need a more sophisticated item for your needs. More like a security light fixture with a separate sensor and socket that you use a regular bulb in.

I found that the connector on the wires was a little difficult to seat in the receptacle on the smoke alarm. You might look at the connector to be sure that the pins didn't bend. There is a "key" on the connector and the receptacle so that it should only mate one way.Also, did you put backup batteries in the alarm?Did the green light work in the old alarm?

I have 5 detectors and one co2 unit all connected to each other and it works fine. If you have more and a larger sized home I recommend the units with the voice warnings so you know which one had been activated. Use sticky notes or tape to ID each one when you do the set up

Yes, this is a direct replacement for the 240 coe. A couple of notes on the swap. The old detector is a wide rectangle. There is a plate available to cover up the holes from the old one if you don't want to repair the screw holes in the wall. The big thing is to find out if you have more than one detector on one zone of the alarm. If not you are fine. If you have two or more you actually need a 6 wire connection between the two detectors to maintain proper supervision. In this instance it is a 4 wire from the panel to the first detector and 6 wire out to the next detector. Also ensure that the end of line resistor is installed as shown in the manual. It ensures that when the sensor reaches its end of life in 5 or so years it puts the zone in trouble so you know it is time to replace it.

Can't give you an accurate measurement, as mine is high up on my wall right now, but as I recall, approximately 2.5-3 inches apart. The detector was very easy to mount.

That depends on the regulations in your area. Maybe ask your local building inspector. My experience was that the connector for the Kidde smoke detector that was already there did not work well with this unit. There were false alarms. It worked well after the correct connector was wired in, but it does not trigger the other Kidde detectors in the house.

The SA521CN has a third wire on the power connector to support that. BUT it will only work if the rest of your smoke alarms are also First Alert SA521CN's (one's made recently) or a similar model (the First Alert website lists which other models that the SA521CN is compatible with). It might not work if have SA521CN's that are several years old because some design changes might have been made (you will need to check with First Alert). The later happened to me with another brand of smoke alarms. It definitely will not work if your other smoke alarms are made by another company like Kiddie.

I replaced my original that was damaged and it looks just like the one that was on the truck. I did have to use the old brackets because I have the towing package.I believe the sensor hole is for an optional back up alarm.

The house was already wired for the alarm. The old unit stopped working so I had to replace it. All I did was connect the 3-wire plug that extended out from the ceiling into the new alarm. I didn't need to use the 3-wire plug that came with the unit. Sorry I couldn't help more.

The one I received did not work well at all. I put a test subject on the ground and it would not detect it if the detector was more than one inch above it, sometimes it would not detect it at all.

The item I bought has the motion detector with it, now if you are wanting to add another one I don't know if you can do it with this one without purchasing another unit. Hope this helps!

The punch code unit (not sure about window alarms) has some flexibility. Meaning the sensors do not need to be perfectly line up next to each other. I have my sensor a little over 1/4 inch off. I mouned the punch code on my door using 3m command strips, so as to not drill into the door, then used double sided sticky tape for the magnetic sensor onto my door frame.

The detector slides out of the bracket just like the stock one. So very quick and easy to do. I wouldn't recommend trying to slide it back in while driving though.
