Can you mix brands of hardwired smoke detectors?
Likewise, can different brands of smoke detectors be interconnected?
You cannot interconnect different makes of alarm, they have different signalling. Buy one of the same make and don't mess around. Smoke alarms provide a degree of safety - only fit and use them in accordance with the maker's instructions.
Also Know, how do hardwired smoke detectors communicate? The electrician runs the red wire from alarm to alarm to interconnect them. When any alarm detects a fire, it sends a 9-volt signal on the red wire. Most alarms can handle about a dozen units intercommunicating on the same red wire. It's a very simple and a very effective system.
Thereof, are all hardwired smoke alarms the same?
Most hard-wired smoke detectors have a connection from the electrical wires to the smoke detectors that engages and disengages. It's like a plug. The key is knowing what connector your smoke detector has so that you buy a new smoke detector with the same connector.
How do hardwired smoke detectors work?
Hardwired simply means that the smoke alarms are physically attached to your home's electrical wiring. The term is used to distinguish this type of smoke alarm from the less expensive, more easily changed smoke alarms that adhere to the wall with double-sided tape or are attached with screws and that run on batteries.
