Do hardwired smoke detectors have to be the same brand?
In general, you will be better off using the same make and model for all units. and units that are supposed to be compatible will work together. Other units may or may not work together, or may mix up a smoke alarm versus a carbon monoxide alarm, so don’t mix them!
Where should CO detectors be placed in a home?
Because carbon monoxide is slightly lighter than air and also because it may be found with warm, rising air, detectors should be placed on a wall about 5 feet above the floor. The detector may be placed on the ceiling. Do not place the detector right next to or over a fireplace or flame-producing appliance.

Why is my smoke detector blinking red every 15 seconds?
WHEN UNITS ARE INTERCONNECTED, only the red LED of the alarm which senses the smoke or is being tested (the originating unit) will flash. The red LED will illuminate for about 1.5 seconds every 16 seconds to indicate the memory condition. The memory will remain activated until pushing the Test/Hush Button resets it.
What causes smoke detectors to go off randomly?
The most likely reason smoke detectors go off unexpectedly is that people aren’t changing the batteries in them often enough. That’s because smoke in the air will reduce the current. If your battery is dying, the current that’s flowing through your sensor also goes down. And so you can get a false positive.
