Do smoke alarms need to be on a dedicated circuit?
Also, how many smoke detectors should be on a circuit?
A maximum of 18 compatible units may be interconnected (Maximum of 12 Smoke Alarms). The same fuse or circuit breaker must power all interconnected units. The total length of wire interconnecting the units should be less than 1000 feet (300 meters).
Also Know, are all smoke detectors on the same breaker? Assuming they were installed correctly, are the 6 identical smoke detectors in my house on the same circuit? Normally yes, but it doesn't necessarily have to be that way. If they're the newer interconnect then it's easier to simply loop one line throughout the house (people almost always take the easy way out).
Keeping this in consideration, can you wire smoke alarm to lighting circuit?
Mains Powered Smoke & Heat Alarms – hard-wired interconnection. All of Aico's mains powered smoke and heat alarms again require a permanent 230V AC mains supply which can be taken from a local lighting circuit or a dedicated circuit at the distribution board.
How many amps does a smoke detector use?
These devices are typically connected to a 120-volt, single-phase, 15- and 20-ampere branch circuit and include battery backup within the smoke alarm.
