What else can I help you with?
What element is used to make light sensitive photo cells for camera electric eyes and fire alarms?
It used to be Selenium, but modern photocells use silicon (Si).
Which car alarms are the most sensitive?
The most sensitive to touch car alarms are Viper, Ultra Star, Prestige, and Code Alarm.
What kind of products does BRK produce?
The company, BRK produces electronic safety devices. BRK produces smoke alarms, battery and electric smoke alarms, plug in alarms and fire extinguishers.
How many types of smoke alarms can you get?
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.
How sensitive are car alarms to wide animals and pets?
Car alarms are most often triggered by accident. Depending on the sensitivity of the car alarm and if it includes an optional sensors, a pet or wild animal could set off an alarm. Sometimes even bugs can set off car alarms.
Why do dogs hate alarms?
The noise is too high pitched and loud, their ears are much more sensitive than ours and it can damage them.
What are the differences between a photoelectric smoke alarm and an ionization smoke alarm?
The main difference between a photoelectric smoke alarm and an ionization smoke alarm is the way they detect smoke. Photoelectric alarms use light to detect smoke particles, while ionization alarms use radioactive particles. Photoelectric alarms are better at detecting smoldering fires, while ionization alarms are more sensitive to fast-flaming fires.
What are the benefits of using optical smoke alarms in comparison to other types of smoke detectors?
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.
What element used in fire alarms?
alot and i mean alot of americium and iron and metal for the sound too just to help out
How sensitive are interlock systems?
Interlock systems are designed to be quite sensitive to ensure safety and prevent unauthorized access or operation. Their sensitivity can vary based on the specific application and technology used, ranging from simple mechanical locks to advanced electronic systems with sensors and alarms. In industrial settings, for example, they must respond promptly to changes in conditions to mitigate risks. However, overly sensitive systems may lead to false alarms or unnecessary disruptions, requiring careful calibration.
When was the electric eye invented?
The "electric eye" (photoelectric switch, photosensor) was invented in the 1920's and used for various purposes such as counting vehicles at toll booths and for burglar alarms.
What are the benefits of using photoelectric smoke alarms in homes for fire detection and safety?
Photoelectric smoke alarms are beneficial for fire detection and safety in homes because they are effective at detecting smoldering fires, provide early warning of potential danger, reduce false alarms from cooking smoke, and are less sensitive to dust and other particles, making them more reliable for long-term use.
