Yes. You can replace a smoke detector with a combination smoke/CO unit. All modern First Alert and BRK alarms use the same wire harness and connector. … For example, if you have 5 smoke detectors interconnected with one combo unit, only the combo smoke/CO unit will sound the CO alarm.
Beside this, are all smoke detectors universal?
Unfortunately, not all smoke alarms are created equal. This is because two different types of sensors exist for detecting fire and smoke. Those two sensors are called “photoelectric” and “ionization” sensors, and they both sense vastly different types of smoke and fire.
Beside above, can you install a smoke detector yourself?
A battery-powered smoke detector installation is simple, and anyone can install one. You’ll need a stepladder and drill, and typically, there are four screws to place the base plate of the smoke detector on the wall. Then you’ll install the required batteries where indicated on the base, the place the cover over that.
Can you interconnect different brand smoke alarms?
This will depend on the individual manufacturer. However, at present we do know that it is technically possible to interconnect up to 30 alarms, but the limiting factor is likely to be the distance between alarms and obstructions that may block the radio signal.

Do I need an electrician to replace hardwired smoke detectors?
They are hard-wired into our electrical system, but that doesn’t mean you need an electrician to replace them. Modern hard-wired smoke detectors don’t have wires in the back that need to be connected to loose wires in the ceiling. … This connection makes it simple to replace bad or old smoke detectors with new ones.
How do I know if my smoke detectors are interlinked?
Most alarms have a test push button as standard. Press this test button for approximately 5 seconds and the alarm should sound. If the detectors at the property are interlinked, they too will also sound. Any smoke alarms that do not sound should be investigated immediately.
