How does a smoke alarm work?
press onThere are two kinds of smoke detectors. 1. When a fire burns, it releases smoke. The smoke detector senses the smoke. 2. A fire is very hot. The detector feels the heat. A smoke detector will then either set off an alarm, or it will turn on the sprinklers.
What is the difference between manual and automatic fire alarms systems?
An automatic alarm system detects fires and sets off the alarm even if there is nobody around to detect the fire. A manual system will only go off when someone pulls the alarm switch after smelling or seeing smoke or seeing or feeling heat of a fire.
Are fire alarms and smoke detectors the same thing?
The terms can sometimes mean the same thing: a self-contained smoke detector with a built-in fire alarm.However, they are technically different and can be obtained in many types.A fire alarm SYSTEM can contain smoke detectors, heat detectors, manual pull stations and other sensors related to fire protection, including switches that say the fire sprinklers or the commercial kitchen fire extinguisher has activated. All of these sensors and switches are wired to a fire alarm control panel that monitors them constantly for electrical trouble or for alarm conditions, relaying the alarm message to bells, sirens, strobe lights and maybe even calling the fire department.Most people say "smoke detector" when they mean "self-contained smoke alarm". The smoke alarm does not usually connect to anything other than maybe another smoke alarm or two, so they all make noise when there is a fire, but someone still has to remember to call the fire department.
Why does the smoke alarm go off when someone burns toast?
Smoke alarms are hung so that if there is a fire you will know it. If toast is smoking then the alarm will detect it.

What is fire alarm system and heat detection system?
They can be the same thing. Fire Alarm Systems are electronic systems which are designed to warn and alert people in the case of a fire. These systems usually contain a central fire alarm control panel, a manual call point and smoke/heat detectors. The heat detectors and detect heat and set off the fire alarm and the smoke detectors detect the smoke from a fire to also set of the fire alarm system. The manual call points are pressed, smashed by someone in order to set off the fire alarms to warn occupants that there is a fire. Heat detectors and usually used in kitchens, bioler houses etc where a lot of smoke/stome is produced, thus stoppping false alarms. Although, you can get seperate heat detection systems which nearly do the same job as fire alarm systems, just with heat detectors.
