The type of smoke produced by a fire depends on the type of fire. Flaming fires produce a different type of smoke than smoldering fires.
Should I get a dual sensor smoke alarm?
Dual-sensor smoke detectors combine ionization and photoelectric technology to detect both flaming and smoldering fires, offering you the best protection and saving you the hassle of installing two separate smoke detectors. But you may still need to install carbon monoxide detectors, if appropriate for your home.
What are the 3 types of smoke detectors?
There are three types of smoke alarms, ionization, photoelectric and a combination of the two which is commonly called a “dual” detector.Do interconnected smoke alarms need to be on the same circuit?
All interconnected smoke alarms must be supplied from the same circuit. A common Neutral must be used for the Interconnect to operate. DO NOT connect the Interconnect wire to Active or Neutral.
What is a single station smoke alarm?
“Single station” simply means that you have one smoke alarm in your home. If you’ve installed a double-station system of alarms, then you have more than one unit, and they’re hardwired together so that, if one goes off, the others follow and sound their alarms no matter how far from the smoke and fire they are.

What is the difference between an ionizing and photo electric smoke detector?
Ionization smoke alarms are generally more responsive to flaming fires. … Photoelectric smoke alarms are generally more responsive to fires that begin with a long period of smoldering (called “smoldering fires”).
Can you interlink different smoke alarms?
Up to 50 smoke, heat or carbon monoxide alarms can be interlinked in a network for maximum coverage. … Additional smoke, heat, CO and specialised products such as strobes and pads and low frequency sounders for the deaf and hard of hearing can easily be wirelessly added or removed.
How do I know if my smoke detectors are interlinked?

What type of smoke alarm is interconnected?
When smoke and carbon monoxide (CO) alarms are interconnected, each alarm can now tell you when there’s smoke or carbon monoxide in any room that has a smoke/CO alarm. A traditional alarm can alert you to the presence of smoke, fire or carbon monoxide, but it can only detect the area around it.
How do I know if my smoke detector is photoelectric?
If you are unaware which type of smoke detector you have in your home, now is the time to check. You can do so by taking the smoke alarm down and look at the back for either “Photoelectric” or “Ionization,” or a symbol with the letter “P” or “I” on the back.
