Q:Does Kidde Firex smoke alarm with KA-F2 adapter replace Firex 120-538B smoke Alarm?
by|Feb 1, 2024
1 Answer
Answer This Question

A:  Yes. You will have to take down all of the older alarms before putting up any new alarms. You will have to change out the mounting brackets at each location but that will just take a screwdriver to change out. You will either have to change out and rewire the wiring harness plugs at each location or you can choose to use the KA-F2 adaptors to adapt the old plugs to our new alarms. The adaptors would plug into the old plugs and the new alarms would plug into the adaptors.

                Q:Do smoke detectors have different sensitivity to temperatures
                by|Jan 6, 2024
                1 Answer
                Answer This Question

                A:  No. And yes. All residential smoke detectors should only be used in areas that are kept between 40 degrees and 100 degrees at the location of the alarm. Ionization alarms can be affected by very high heat and very high humidity, such as steam or heat from cooking or a shower, and the alarms can be made more and more sensitive until they can be set off for a false alarm. Photoelectric alarms are less affected by steam, heat and humidity but enough steam and humidity, especially enough to condense water in the alarm, can still set them off or affect the working of the alarms.

                    A:  Hello. It will use the same wiring harness plug but a different mounting bracket. Changing the bracket just takes a screwdriver and a ladder. However, this is just a smoke detector and does not detect smoke. You might be happier with the Internet # 205711626, Model # 21027519, Store SKU # 1000535870 which is a hardwired smoke and carbon monoxide alarm with the same bracket and the same wiring harness plug
