Nope... Only smoke for smoke detectors!
Interlinked smoke detectors are smoke detectors wirelessly connected to one another. This is a good system for larger homes, and can be found at http://www.safelincs.co.uk/Radio-Interlinked-Smoke-Alarms/.
There are several types of smoke detectors that can be used in the home. Interlinked smoke detectors can interlink smoke and heat detectors for better convenience. Also, wireless units can be configured specifically to your needs. More safety and smoke detector information can be found on: http://www.safelincs.co.uk/Smoke-Alarms/
Photoelectric smoke detectors are advantageous because they are more effective at detecting smoldering fires, they are less prone to false alarms from cooking or steam, and they have a longer lifespan compared to other types of smoke detectors.

There are many types of smoke DETECTORS and self-contained smoke ALARMS. Some smoke detectors use ionizing radiation; others use photo-electric sensors. More sophisticated sensors use chemical reactions to detect specific types of smoke or to measure specific chemical composition and concentration of smoke. Photo-electric sensors are said to be more sensitive to smoldering fires (large particles) than ionizing detectors, meaning you may get an earlier warning from photo-electric.
Tenants are not responsible for anything after they move out. A good landlord will replace batteries in smoke and carbon monoxide detectors every year, regardless of who is renting.
Cheap and effective when maintained properly. Smoke detectors will run out of battery over time as they are not wired in to the houses electrical system. Statistics show that far fewer people die in house fires when smoke alarms are present. When the smoke alarms are placed to close to bathrooms steam may interfere with the detector, triggering false alarms. Ionization detectors seem to respond better with high flames which could be a problem under certain circumstances.
A photoelectric smoke detector uses a light sensor to detect smoke particles in the air. It is different from other types of smoke detectors, like ionization detectors, because it is more sensitive to smoldering fires and less likely to give false alarms from cooking or steam.
Optical smoke alarms are more effective at detecting smoldering fires, which produce larger smoke particles. This makes them less likely to be triggered by cooking fumes or steam, reducing false alarms. Additionally, optical smoke alarms are generally more sensitive and provide earlier detection of fires, potentially saving lives and property.
No, smoke detectors are triggered by detecting smoke particles in the air, not just heat. Heat detectors, on the other hand, are designed to only activate when a certain temperature threshold is reached.
Yes, many jurisdictions require smoke alarms on each level, and perhaps in each bedroom area of a home. Other places only require them in rental homes or where there is some other reason the home may be subject to fire inspections. In addition to smoke alarms, modern codes require carbon monoxide detectors in approximately the same locations as smoke alarms, and several companies are now combining the two functions into one unit.
